Thank Heavens for Sprite Backup

This morning I had one of those real sinking feeling moments. I got to work, pulled out my Dell Axim PDA and plugged it into it’s cradle hooked up to my PC and rather than the usual screen was greeted with a big error message stating that there was memory corruption and asking me to press one of the buttons to continue. Pressing this caused the PDA to reboot, and then go through the first start-up screen calibration routine before dumping me at an empty today screen.

Now this isn’t the first time this has happened. The first time I had to reinstall all my applications, fix all the configuration – basically it was a long job. After that experience I looked around and bought a copy of Sprite Backup a bit of software that does a significantly better job of backing up a Pocket PC device than the included option. Every morning when I plug in my PDA it automatically takes a backup of the contents of the device – this morning I was very grateful that it did.

The only thing I had to install back onto my PDA was the Sprite Backup software, and then I just had to configure that to use the ActiveSync connection to talk to the other part of Sprite Backup on the PC. Then I just had to select my last daily backup and click the start button. Twenty minutes later after replacing all the missing files and putting back on all my settings the PDA rebooted and everything looked as it should. Then you only have to wait a few minutes whilst ActiveSync, which unfortunately decides that all the replaced contacts and calendar entries are new sorts itself out (just a question of letting it replace the data – the stuff in Outlook is probably more up to date than the backup anyway), and then everything is back to normal.

Seriously, if you’re running a Pocket PC PDA, something like Sprite Backup is an absolute life saver. True if you’re syncing your calendar and contacts to a desktop your information is relatively safe, but even then it still does take a lot longer to rebuild if you have to manually reinstall all your applications – Sprite Backup does the lot. The backup each morning is a bit annoying at times, but I’ll happily take that instead of the frustration when invariably the Pocket PC crashes.

Terastation

Over time, as the volume of data we’ve got sitting around has built up, the prospect of what would happen were a hard drive to go wrong has become more and more of an issue. Whilst we could reinstall software, loosing things like our digital pictures is a lot more of an issue.

For a while I’ve been picking up external hard drives, which are okay, but what I really needed was something big that could take backups of everything. After searching around, I looked at building my own network attached server using an old PC, but price wise it seemed better to go for something built for the job as I’d have to spend a bit of money bringing an old PC up to a suitable spec. I eventually went for the Buffalo Terastation, a unit that contains four separate 250Gb hard drives, which can be configured in a number of ways. Out of the box it is set up in a single 750Gb RAID-5 array – which balances size over security – in theory were one of the four drives to fail and have to be replaced, the unit would be able to rebuild the missing data automatically from the remaining three drives. On paper the unit also supports both the PC’s and the Mac, offering Windows networking, FTP and also AppleTalk. The only major standard it doesn’t support is NFS.

The unit actually arrived a couple of weeks ago, however one problem I quickly discovered is that whilst it isn’t particularly noisy, it does vibrate, more annoyingly the vibration level varies in a regular cycle which at certain frequencies resonates the floorboards in the house. This means that whilst it is relatively quiet in the room upstairs, downstairs it is much more audible. I’ve paid a visit to QuietPC and it’s slightly better, but I’m still not leaving the unit on unless I’m backing up to it.

Today I started on the backups. On the PC I’m using Acronis True Image, as they have finally added support for XP64 to their home product. The problems I’ve run into with the Mac side though are down to combinations of limitations with the hardware and the software. I’ve had a copy of Superduper for a while, and it’s a nice little bit of software for backing up hard drives, with some nice features. However when it comes to backing up to a network drive, the suggested solution is a big problem – using a mountable disk image.

Looking at the Terastation there are two choices for mounting a share up on the Mac, using the Windows networking, or AppleTalk. In terms of speed, AppleTalk is by far the best, however it has a major limitation – the maximum file size is 2Gb. Now I don’t have any 2Gb files sitting around, so all would be fine if Superduper would do a straight backup, but it won’t. As it is creating a drive image, this is going to end up as over 2Gb, so it’s back to the much slower Windows networking implementation. It is worth noting that Apple only really retain AppleTalk for backwards compatibility, their favoured option being NFS – indeed a read of their Windows Compatibility document finds them recommending using AppleTalk and NFS over Windows networking for home directories. The other way around the problem may be to use FTP instead – create the backup image and FTP it across. Some further experimentation is called for methinks.
