June 13, 201115 yr Hello unRAIDers, I have setup a user share for time machine backups and I want to limit the size that my machines see available in the share. Is there a way to accomplish this using the settings in the management utility or unMenu? In this case, I will want to limit the size the share has available to 500 Gb. I would prefer to NOT use a dedicated drive and disk share, if possible. I found some ways to do this in Mac forums, but they require using the disk utility to create volumes and I don't know if this works on an unRAID share. Any thoughts would be appreciated. TIA, erik

I use the disk utility to create a volume on unRAID which I mount as needed. It works well.
June 13, 201115 yr You could try setting the "min free space" very high. I don't know how well TM will like this once the limit is reached.
June 13, 201115 yr I'm currently attempting this. Using a user share on a drive shared with another user share. Just started so I'll let you know how it goes, but so far so good.
June 13, 201115 yr I'm running a test as well. I'm limiting a a 2T drive to 1T by setting the "min free space" to 1048576000. I have not yet reached the limit.
June 13, 201115 yr Author Interesting idea, dgaschk. I guess i would need to limit the share to a specific drive to make that work correctly using min free space. I might go ahead and try mounting a volume on the share to see how that works, mcs. Are you mounting your TM volume on a user share or disk share? Does it matter? From what I understand, Time Machine is supposed to fill up all available space, then start deleting old files when it runs out of space -- first in, first out. If this is true, then it should be OK with a limited amount of drive space. I was thinking about 500Gb for backing up a MBP and an iMac.
July 22, 201114 yr Hey guys, Long time lurker, but I just registered today. This is exactly the same issue I have. I'm going to be building a HTPC soon, and I want to use the unRAID box I'm going to be building to back-up that HTPC. I also want to use it to back-up all of the macs I have. Like erik mentioned, Time Machine will keep going until it eats up the drive, and then it will delete older backups. I'd like to specify a max size for the user share, that way I don't need to worry about my HTPC video storage being eaten up past a certain point. Is there the thought that this might become a feature in the near future? It doesn't seem like it would be terribly hard to implement....
July 23, 201114 yr Yes. Limiting a share size is a planned feature. Fantastic! Is there a road map for this? Will we be able to expand share size, just like we an expand the unraid array? Also, is this similar? I just saw this in the beta release notes: afp: added "TimeMachine volume size limit" parameter for AFP
