Welcome back to Ask TUAW, our weekly troubleshooting Q&A column. This week we've got questions about the Trash, Migration Assistant, Safari Bookmarks, Mac mini Server, Windows and Mac file sharing and more.

As always, your suggestions and questions are welcome. Questions for next week should be left in the comments. When asking a question please include which machine you're running and which version of Mac OS X (we'll assume you're running Snow Leopard on an Intel Mac if you don't specify). And now, on to the questions.

CL asks:

Is there any way to just delete a single item in the trash can? I only see options to empty the entire trash can?

Unfortunately, as they say in computer parlance "That's a feature, not a bug." At the moment, Apple only allows you to go for an "all or nothing" approach to emptying the trash. Of course, the best solution is to only put things in the trash you want to delete. But I'm sure you already thought of that.

Lamdavidortez asks:

I will be upgrading from my current February 2007 Macbook Pro that is running Leopard to a new October 2009 MacBook Pro that is running Snow Leopard I plan on transferring my data via the "Migration Assistant" but being that this is the first time I perform this type of operation ... I want to make sure that I do not run into any issues.

Are there any precautions I should take? My other concern is that I backup my current 2007 MBP via Time Machine to my Time Capsule. What will happen to that data once I switch over to the 2009 MBP? Will I still have access to that data? Will it be rendered useless?

Migration Assistant has been around for several years now and has evolved and become better with each successive update. There was a time when I would never consider using it and did things the manual way by copying each and every thing I needed individually from an old Mac to a new one. Now, Migration Assistant is good enough and, more importantly, reliable enough to be used on its own. So, migrate away.

Many Mac pros are unnaturally fond of SuperDuper!, the accurately-named backup utility from Shirt Pocket Software. The application is inexpensive (free, actually, if you don't want advanced features -- the best US$27.95 you've ever spent, otherwise), powerful, and easily makes fully-bootable backups of your Mac.

The latest version of SuperDuper! has just been released. Version 2.6.2 is now available and has a ton of new features and fixes. Here's the scoop from the revision history:

• Significant copy speed improvements (up to 2 times faster!)
• Preserves compression when copying
• Fixed extra copying under Snow Leopard
• Scheduled copies in old format are now disabled and we prompt the user to recreate
• Scheduled copies work on Japanese systems and with more Unicode/composed character drive names
• Backup-on-mount should work on 10.4.11
• Adjusted SDUtil path to improve robustness when application is moved (now symlinked/refreshed)
• Minor copy tweaks
• Reworked SL status to use 1000B = 1MB, 1024B = MiB for Leopard and earlier.
• Fixed crontab escaping if user has tcsh as their default shell
• Fixed issues with explicit Spotlight disable/enable under 10.5+

If you currently have SuperDuper!, you'll be notified of the update the next time you fire it up. If you don't have it, get it.

Thanks to Scott for the tip!

About 13GB of data was accidentally deleted from my account on my Mac yesterday. Fortunately, due to an aggressive backup system, I was able to recover all of the files.

I was trying to test out a tip sent to the TUAW team, which led me to log into (and out of) the "Guest" account several times. One of the logins seemed to hang, which triggered a memory about a data loss bug in Snow Leopard which I had read about (and which Apple is now acknowledging in "extremely rare" cases, per Cnet). I immediately reached around the back of my iMac and shut it down.

At first I thought everything was OK, but then Dropbox started asking me to configure settings, as if it was the first time the app was run. Fortunately, due to the new "LAN sync" feature in recent Dropbox betas, the iMac copied my Dropbox files from my MacBook Pro on the same network in a matter of seconds, rather than having to download almost 2GB of data from Dropbox's servers.

I thought that was the end of the problems, until I saw that my Terminal customizations were missing. Then I noticed that a few other applications were not functioning correctly. Suddenly I realized that I had most likely suffered more data loss than was immediately obvious.

Read on to see what had to be done to recover after the data loss occurred.

You may not have heard about the recent loss of data for T-Mobile Sidekick users; after all, this is an Apple-focused site and there probably aren't as many Sidekick owners out there as there are iPhone users. I'll explain the situation, and how it could happen to anyone depending on cloud-based data stores for their mobile devices.

The Sidekick is made and supported by Danger, which since April of 2008 has been owned by Microsoft. As such, all of the personal information on the Sidekicks was stored on servers owned and operated by Microsoft. During the last week, Danger / Microsoft had hired Hitachi to do an upgrade to their Storage Area Network (SAN). That's usually not a problem, as the owner of the data (Microsoft in this case) performs a backup of all the data in case of an issue.

Well, something went wrong, and it appears that Danger / Microsoft did not have a backup in place. The result is a catastrophe for Sidekick users. T-Mobile sent out a statement last week explaining the situation, and placing the blame directly on Microsoft and Danger: "Regrettably, based on Microsoft/Danger's latest recovery assessment of their systems, we must now inform you that personal information stored on your device -- such as contacts, calendar entries, to-do lists or photos -- that is no longer on your Sidekick almost certainly has been lost as a result of a server failure at Microsoft/Danger."

As data backup and media servers become more prevalent, they also become more complicated, with ever more devices to sync and ways to store information. Today, Iomega released a new NAS appliance that can serve as both a backup device and a media server with a view to streamlining the setup process for home or small business users, while implementing a few features that are more commonly seen in larger-scale networked servers.

The newest iteration of Iomega's NAS appliance line, the dual-drive StorCenter ix2-200, has many of the features that you'd want to see in a media server or a backup target. As a backup device, the StorCenter can be set up as a Time Machine target for Macs and for remote access, so that the user can manage and upload or download files from anywhere with an Internet connection. It has three USB ports that allow direct interaction with other devices, such as external drives or a printer (the unit can act as a print server).

Iomega's put quite a few other bells and whistles into this NAS. The unit can stream media to Xbox 360 & PS3 consoles, and to many iTunes-compatible music devices. It's also Bluetooth-capable, allowing a smart phone to sync with it, but this requires the separate purchase of a USB-Bluetooth dongle. The StorCenter is VMware-certified as an iSCSI and NFS storage device, supports direct streaming from up to five Axis network cameras, and can even serve as a BitTorrent client.

One of the more interesting features for backup use is the device-to-device replication. The StorCenter can be set up to perform any number of "copy jobs" to sync data automatically to and froms various devices and files at scheduled intervals. It also has a QuikTransfer button on its front, to which you can attach any number of copy jobs that will be performed automatically when pressed, rather than having to wait for scheduled maintenance. For example, if you regularly import videos to your computer and want them backed up, synced to the computer upstairs, and put on another external hard drive you carry with you, you can plug the drive into the StorCenter, press the copy button, and voila! It's all done at once! (Of course, you have to set it up that way first. It's a button, not a mind-reader.)

Welcome back to Ask TUAW, our weekly Mac troubleshooting Q&A column. This week we've got questions about backing up photos, removing a Boot Camp partition, Snow Leopard and Windows 7, Bluetooth menus, iPhone search results and more.

As always, your suggestions and questions are welcome. Questions for next week should be left in the comments. When asking a question please include which machine you're running and which version of Mac OS X (we'll assume you're running Leopard on an Intel Mac if you don't specify). And now, on to the questions.

Han asks:

What is the best way to archive photos without using iPhoto? I have about 100 GB of original photos and I have been saving them on my NetGear ReadyNAS Duo. Sometimes I leave the photos in the folder and just copy it to the NAS or sometimes zip them before I put it in the NAS. What I am worried about is if I zip the folder and somehow the zip file itself gets corrupted, is it harder to recover them? Is it better to just not zip and leave it as a folder then copy it to the NAS?

Because photos are pretty important and almost impossible to recreate I take my photo workflow and backup seriously. First, I never import photos directly into iPhoto and instead, using a card reader, copy the files to a folder I have labeled specifically for these photos which resides in my main "Photography" folder.

Data Robotics delivered their "super-sized" version of the Drobo earlier this year. DroboPro has 8 drive bays into which you can drop 3.5" SATA drives of almost any capacity, from the old 160 GB model you've been using to hold the backup of your iTunes library to that 2 TB Western Digital Caviar drive you just purchased. Using a proprietary storage technology called BeyondRAID, Data Robotics makes it easy to use a DroboPro to give you a big box 'o storage right now, and easily expand in the future.

Data Robotics recently lent me a DroboPro for a detailed review, and I was able to give it a thorough workout. Read on to find out more about the DroboPro and an excellent deal available to readers of TUAW.

One of the largest personal iTunes libraries I've ever seen belongs to a client of mine. This client, who was a DJ in the 50's and 60's, has a huge collection of vinyl albums and singles that he painstakingly digitized, cleaned up, and catalogued in iTunes. Needless to say, opening iTunes on his Mac Pro is an exercise in patience.

Thinking about his music storage needs, and the huge amount of digital photos and video that my wife are accumulating, got me musing about other ways to do mass storage inexpensively. At this point, I'm probably OK with a DroboPro, but what if I needed petabytes (1 petabyte = 1,024 terabytes = 1,048,576 gigabytes) of storage? Most solutions at this point in time are quite expensive.

As of 6 AM PDT this morning, off-site backup vendor BackBlaze has put their solution to mass storage needs, the BackBlaze Storage Pod, out to the world as an open source project. Their solution is a relatively inexpensive box (US$7,867 for 67 TB of storage) made up of off-the-shelf components that can be reproduced and/or improved upon by others who also need huge amounts of cheap storage. See those red boxes in the picture to the right? Each one of those contains 67 TB of RAID 6 storage in a 4U box. For a petabyte of storage, you're going to need to spend about $117,000 on about fifteen of the boxes.

EMC announced today an update to its popular Retrospect network backup software; version 8.1 brings back support for PowerPC-based workstations and improves performance for Intel-based Macs.

Eric Ullman, director of project management for Retrospect, said that while older G4-based Macs will run significantly slower than their Intel-based counterparts, Retrospect 8.1 can at least back them up (a capability that was lost in the move from the legacy 6.1 version). G5s with multiple processors, however, can see performance gains of 10 to 15 percent compared to Retrospect 6.1.

Intel-based workstations will also see performance increases of 10 to 15 percent compared to 8.0, and 30 to 35 percent compared to Retrospect 6.1. Other improvements, including updates to the user interface based on feedback from early adopters, are also included in the update.

Ullman said that with Retrospect 8, EMC had "recommitted itself to the Mac market" and this update was the second part of a three-phase deployment of the completely-rebuilt Retrospect 8. Phase one was the initial release, supporting Intel processors; phase two now supports PowerPC processors. Phase three, according to Ullman, is slated for release "in the Snow Leopard timeframe," and is expected to include support for importing Retrospect 6.1 sets and configurations, among other improvements to performance and the client software.

As Steve Sande mentioned, Retrospect's update comes on the heels of BRU Server 2.0, which added a new user interface and performance improvements. Ullman noted that BRU Server and Retrospect are fundamentally different, with Retrospect scanning more closely to prevent file duplication and save time copying files. Retrospect is generally less expensive than BRU Server, though their pricing structures and trim levels are a little different.

The update is available now on the Retrospect website. It's free for Retrospect 8 users and Retrospect 6.1 users who purchased the product after January 14, 2008. For new users, Retrospect 8 comes in a variety of flavors ranging in price from $129 to $1,669, depending on the size of the network.

Apple did the world a great service when they introduced Time Machine backups to OS X. Suddenly, anyone could attach an external disk drive to their Mac and have a constant set of backups at their fingertips with little or no intervention required.

However, there was one very big, hairy fly floating in the soup of backup contentment -- if your backup drive was destroyed or stolen, your backup was gone. Many of us who are paranoid about backups started doing a second level of backups to offsite services such as Mozy, Carbonite, or my personal favorite, BackBlaze.

There's a new kid on the block with a different approach to offsite backup -- Time Warp. This US$25 Mac application (free during the beta period) takes your Time Machine backups, compresses and encrypts them with 256-bit AES encryption, and then uploads them to your personal Amazon S3 (Simple Storage Service) account.

How does the cost of storage on Amazon S3 compare with the other services? The current costs are $0.15 per GB per month for storage, $0.10 per GB to backup data into S3, and $0.17 per GB to restore data from S3. The Jumping Bean Software team says that backup up 20 GB of personal data would cost about $1.50 per month, which is in line with costs for the other services. Time Warp does intelligent filtering to keep "dumb files" like cache, trash, and temporary files from being uploaded and costing you money.

If you take a glance at the sample screenshot at the top of this post, you'll notice that Time Warp does its best to give you a handle on your storage costs, so there's no guesswork involved. Leopard users who have been on the fence about whether or not to invest in an offsite backup solution might want to take advantage of the Time Warp beta.

I swear, getting old is not a lot of fun.

Last night, I taught a class in data security for home and small business users at our local community college. There were a lot of good questions from the community education program students, so the class ended quite late and I was still answering questions as I walked out the door.

This morning, I went to grab my MacBook Air out of my laptop bag and literally grabbed air instead. In my haste to get out of the classroom and head home, I had packed everything but the laptop. Fortunately, the classroom was locked and few classes are scheduled for early morning, so I called the campus police and had them rescue the MBA for me. Problem solved!

After actually losing an iPhone 3G a few months ago, I wrote a post about what to do to prevent data loss and identity theft when lose your iPhone, and included a few tips on how to hopefully keep yourself from losing the phone in the first place. In this post, I'll talk about the things that I do (or can do) to keep my MacBook Air and my data safe, even when my mind conspires against me to try to lose the computer.

Time Machine made it easy for Leopard owners to back up their Macs on local external hard drives, and lately we've seen a number of online backup services such as Carbonite, BackBlaze, and MozyPro debut for the Mac platform. These online services are great (I personally use BackBlaze), but there's a monthly cost associated with them. What if you already have access to a large volume of server space?

App4Mac has just announced Twin 1.0 for Mac OS X (US$39.67, €29.00), an online backup solution that works with all sorts of servers: FTP (all varieties), WebDAV, Amazon S3, and even MobileMe. Unlike many of the other online solutions, Twin claims that it retains all the Mac OS X file metadata, ACLs, and privileges, and your data is kept safe with AES-256 "Jack Bauer quality" encryption. In addition to the online backups, you can use Twin for backing up your files to local drives and have the backups begin when the external drive it plugged in.

I'm impressed with the powerful scheduling capabilities of Twin, which include a way to use logical operators to determine exactly when backups should proceed or not. Having an offsite backup is that extra bit of security that every Mac user should have. Check out the gallery below for some screenshots of the app in action. You can also download a free, limited-capability trial of Twin if you're interested in kicking the tires.

Back in December, online backup company Backblaze launched a private beta of its service for Mac users. Like its Windows counterpart, the Backblaze subscription service is $5 US a month (or $50 US a year) for unlimited backup space. Today, the company is officially launching its service for Mac users, along with an updated client, better support for external drives and enhanced recovery options.


Configuration and setup

Just like in the beta, Backblaze remains extremely easy to set-up and use. You just install the program (by default it will run in the background, though you can change this), enter in your e-mail address and password, and it will start backing up your files. The default setting has Backblaze running any time it finds an available internet connection. The backup process is constant and Backblaze stores multiple versions of a file for 30 days (so if you are frequently changing a document or spreadsheet, 30 days worth of revisions are saved to Backblaze).

If you want to remove Backblaze, the company has made the uninstall process easier and more intuitive. There is now an uninstaller built into the install DMG image, just double-click on Uninstall (right next to the install option) and you can take Backblaze off your system. If you trash the DMG, just download it again off the Backblaze web site for easy removal.

Backblaze won't backup your Applications (thought it WILL backup stuff in your User/Library folder, so many of your application settings will remain backed up), but it will backup your photos, movies, audio files as well as things like your iPhoto or Aperture database, various documents, and more. By default, .ISO, *.exe and *.DMG files are excluded from the backup file type list, but you can remove most of those extensions (*.ISO cannot be removed) if you want to backup that information.

The maximum single file size is still 4 GB, but keep in mind this doesn't mean your iPhoto or Aperture databases won't be safe. Those databases are actually just folders with lots of smaller individual files, that's fine. If you have individual files over 4 GB in size, those won't be backed up with Backblaze. You'll need to split the files into smaller segments or make alternate arrangements.

You can find Mac applications that have been around longer than Retrospect, but not many that have the same ratio of copies installed to jobs/sanity saved. The venerable backup tool, now in its third decade and published by EMC Insignia (original developer Dantz was acquired a few years back) has been revitalized in version 8, now shipping, with scores of features that bring it to reasonable parity with the Windows version of the app.

The new Retrospect, which EMC previewed at Macworld Expo, breaks the administrative UI away from the underlying backup engine and allows backup managers to control multiple instances of the tool from one console. Simultaneous execution is supported now, along with advanced disk-to-disk backups, faster catalog rebuilds, single-write/multi-read operation, improved networking and tape drive support, and media & catalog cross-platform compatibility with the Windows 7.6 version. Video tutorials for the new v8 are here.

Retrospect 8, for the moment, only runs on Intel machines but can be used to back up PowerPC clients (PPC support is coming in a near-term update, the company says). Pricing starts at $129US for the Desktop edition with support for 3 client machines (a maintenance plan adds $120), and ranges up to $1700 for the Multi-Server, Unlimited Client version; there are also Single Server 20-client and unlimited client licenses available at intervening price points. Upgrade pricing is available through the EMC site.

If you've been having issues with corrupted Time Machine images either inside the Time Capsule or connected externally to your base station, the 7.4.1 firmware update (for all base stations from 2007 to today) plus the 10.5.6 update might help, according to TidBITS.

Apple says this update will fix problems that lead up to corruption issues, but TidBITS recommends you essentially start fresh just to make sure -- after using the Archive feature in Disk Utility to copy your previous Time Machine disk to an external drive. Don't have enough drives to do the data shuffle? You can always take your chances that you either don't have a corrupt Time Machine backup (which is pretty likely, honestly) or do a little soul/data-searching for anything you might want to preserve for posterity.

I don't use Time Machine as a sort of universal undo, but I understand some might. In either case: update your system and firmware as recommended by the manufacturer.
