Time Machine -
samg -
As I indicated, I only ran (or tried to run) it on 10.5.8. I haven't upgraded to Snow Leopard yet, though will probably do so soon.
The information that I received was from Synology who indicated that AFP had to be enabled for Time Machine to work. Indeed, without AFP enabled and the share hidden, the Time Machine UI didn't even see the Synology NAS.
Initially, Synology said that TM didn't work with anything less than 10.6, but then reported that it would work with 10.5 as long as the Mac didn't go to sleep. That wasn't my experience. I did an initial backup, and after that, Time Machine failed when trying to connect to the Synology NAS.
FWIW, Synology suggested that as a possible work around, you could enable iSCSI on the NAS and set it up a target. They provided the following link as free tool to mount the iSCSI target. I didn't verify it, however.

In theory, the mounted iSCSI target should look like another disk to the Mac, and you should be able to select that as a time machine target.
I tried one other experiment this morning - I disabled disk quotas for my "time machine" user even though that user was 32GB under it's quota. I switched time machine to use the disk station as a target and it backed up successfully. However, I toggled back to the normal disk I use for TM backups and then back to the Diskstation, and it failed again.
I'm really not sure what apple talk has to do with the Mac "seeing" the diskstation as a target. I checked my network preferences, and AT wasn't enabled.
Frankly, I bought my DiskStation about 2 years ago long before the latest upgrade. I was pleased that my old unit got a firmware upgrade, though Synology has stopped upgrading the X06 products, I believe. I just use an external 500GB USB drive that I picked up at a Black Friday sale for my TM backups, so for me, Time Machine functionality in the Synology NAS wasn't (and wouldn't be) a deal breaker.
