Hi,

 

I have been running unRAID for quite some time and I've read somewhere in the forums that it's better not to use the cache option for Time Machine backups. Is this true, and if so why's that?

 

Cheers

Any Mac users?

The cache drive is not protected via parity and any files put on the cache drive will be moved.

 

For something like this I think you would be better off disabling the cache drive for the AFP share.

I disable caching on my TM drive.

 

TM over a network is slow and flakey as it is, no need to really add any more things to it!

 

I'm actually planning on moving my TM drive to my Mac again and using Super Duper to make incremental copies of the TM drive to the array instead.

 

Performance is piss poor unfortunately

I'm curious why you guys want time machine backups in the protected zone at all. Why not add a disk via SNAP to use for time machine backups. They are after all backups of data you already have and maintain on another machine.

 

Unless you're like one of my consulting clients who was using time machine as an extended file cabinet "oh i just delete stuff I'm not using 'cause it's in Time Machine."

I've had a TM drive fail and loose the protection of having hourly backups.

 

TM isn't *just* a backup. It's a OMG I want that version from two weeks ago system.

 

Using TM as just a *there is another copy on that disk* is completely pointless. Might aswell use CCC instead tbqh.

I've found my time machine volumes (usually USB drives) on my macs corrupt themselves and have to be reformatted and started from scratch about once a year.  Thus I don't use time machine for version control, I either save numbered versions and keep them or use GIT. I guess I'm just old school in that the only backup I really care about, is the most recent one.

You guys convinced me about not using Time Machine, instead I've set up a CCC job to run once a day. That's completely enough for me, the super important stuff is in my Dropbox anyways. I don't need version history at all.

I'm using TM on a WIFI laptop with version beta 14 with no problems, performance or otherwise.
