the ReadyNAS forums. Note that the advice is by no means specific to ReadyNAS drives (I have a Thecus NAS myself). Many thanks to btaroli in that thread for the insight. Time Machine Time Machine is Apple's easy-to-use backup system, baked into OS X (as of Leopard). Unfortunately it doesn't allow you to back-up to a networked drive out of the box. Enabling this ability is pretty easy. Early on there were some reliability issues - which were largely time machine error 45 goflex due to the fact that Time Machine created a disk image (more specifically, a sparse bundle) on the network drive, and this was prone to corruption if the network connection was disrupted during a backup. I don't know if all the issues here have been entirely resolved now, but it does seem more reliable. Apple's own Time Capsule, which has been specifically designed to work with Time Machine, uses this same method, so it is no longer an entirely unsupported technique. Enabling Time Machine for network drives So how do you enable backing up to network drives? Open a terminal window and paste the following in (then hit return, of course): defaults write com.apple.systempreferences TMShowUnsupportedNetworkVolumes 1 Mounted network drives will then show up in the list of destinations available for storing backups. Getting a working disk image Unfortunately this is not always enough. Often, after doing this, Time Machine will appear to start preparing a backup then fail with a cryptic error code. The error I have seen is: Time Machine could not complete the backup. The backup disk image "/Volumes/backups-1/Wall-E.sparsebundle" could not be created (error 45). "Error 45"? What's that. If I try to create a sparse image myself in the same location I'm told, "the operation could not be completed". This is not much more helpful. If you google there are many references around to these errors - mostly in foru

The first time machine setup worked fine and I got to backup my Mac probook just fine. After a http://www.levelofindirection.com/journal/2009/10/10/using-a-networked-drive-for-time-machine-backups-on-a-mac.html month I got error messages saying backup failed. now I try to create a new backup by 1. selecting backup disc NONE and then 2 creating new backup -selecting the backup device and time machine tries to "make disc space available" - this is taking about 2 minutes. Then I get an error message: Time machine could not complete the backup.

I have no problem accessing the network drive at all thanks Kai Reply With Quote 26th December 2010,08:23 AM #2 snark Join Date Apr 2005 Location Melbonia Posts 2,192 In my experience, backing up using Time Machine to a disk connected to your wireless router works perfectly well - until it doesn't. I had the same thing happen to me when I used a NAS drive. Unless you are using a Time Capsule, you really are better off connecting the disk directly to your machine.

Because Time Machine uses a dual-ended checksum protocol, it is only compatible with a directly-connected USB/FW/SATA drive, a networked Time Capsule, or another Mac running OSX 10.5.2 or greater. Even though Apple's own AEBS lets Time Machine save its backup bundle to an AirDisk, it is officially unsupported. Once a Time Machine archive develops a fault, the entire archive is un-usable, and should be deleted and the whole backup started over from scratch. Reply With Quote
