But do yourself a favor and maintain some sort of secondary backup, such as a "clone" via CarbonCop圜loner or SuperDuper, or some other backup app. That post obviously applies to Leopard Snow Leopard appears to have added some requirements, that are also not supported by all NAS devices: some that were working with Leopard no longer work with Snow Leopard.Īs long as you understand the risks, it's your call. To summarize: if you care about your backup data you should avoid using non-natively supported AFP servers. If you have to trick the OS to use the volume it means the NAS does not support it. If the NAS you are using supports these features it should report them to the OS and you should natively be able to choose that volume. Time Machine appears to rely heavily on disk journaling to deal with network drop-outs, interrupted backups, and the like. If you can't guarantee that (e.g., because of network/NAS buffering) then the journal is useless. Remember, journaling relies on the journal being written all the way to disk before the changes take place. Without such features, a network interruption can result in a corrupted filesystem on the disk image despite journaling. These presumably allow the disk image engine to force disk image journal data to write out all the way to the disk. There were additional features added to AFP in 10.5 to support Time Machine. The technical reason why Apple limits Time Machine to 10.5 AFP volumes appears to be to prevent disk image corruption. You may be able to get it to work successfully, but there's no guarantee it will work well, or in the future.įrom a post in another forum (found by V.K.): You do need to know that Apple may not support this: Here's the official word: I hope that the Western Digital people will create greater flexibility for Time Machine users in future firmware updates. How our Time Machines will battle it out for the disk space, I have no idea.)
(I have the further issue of having two Time Machine backups, one for me, one for my wife. Since I could not partition the MyBook World Edition II, what I did instead was to enable the "Quota" functionality and then put a disk quota on the WD_Backup user. Thus, the Time Machine backup will eventually fill up whatever space is given to it. The reason I wanted to set up a partition, where I could limit the disk space, is that I read that Time Machine creates daily backups, with incremental versions of documents. This is not possible, as far as I can tell, because the MyBook World Edition II shows up as a "share," not a "device" in the system, and therefore Disk Utility does not see it.ĥ. Also, some instructions direct you to make a partition on your drive for Time Machine using Disk Utility. That used to be true but with the firmware update, is no longer true. Ignore some of the misleading statements in the Western Digital "knowledge base." For example, it says Time Machine is not supported.

On my device, it was "admin" but other posts say the password can be "backup" or "wd_backup."Ĥ.

BUT, what the instructions don't tell you is the password for that user, which Mac OS will ask you for during the Time Machine setup. MyBook World Edition II comes with a built-in user, WD_Backup, which appears to be the only user that can be used for the backup.
Amazingly, the Level I support people at Western Digital told me that Time Machine is not supported! I had to point him to this link.Ģ.
#How to enable time machine on mac upgrade
The MyBook World Edition II NAS does support Time Machine - if you upgrade to at least firmware Release 1.01.14 (9/29/09). It's not so straightforward, and the information on the Western Digital support site is either unhelpful or flat-out wrong, so here's a post that will hopefully save people in a similar position a lot of time and frustration.ġ. I have just successfully set up Time Machine on my MyBook World Edition II NAS.
