4.2.25 & 10.9 Time Machine Capacity?

After digging around a bit, I was able to use the following fix on my device...

You will need to enable root SSH access first (this can be downloaded as an add-on)

1) cd /var/lib/timemachine
2) vi .AppleVolumes
3) Change this line --> /c/.timemachine [device-name] cnidscheme:dbd allow:[user-name] options:tm
to --> /c/.timemachine [device-name] cnidscheme:dbd allow:[user-name] volsizelimit:500000 options:tm

The volsizelimit is in MB and can be adjusted to meet your needs.

4) /etc/init.d/netatalk restart
5) Log into FrontView admin web site and change the Time Machine capacity to be equal to or greater then what was set for volsizelimit above

The reason for the last step is because FrontView uses user quota settings to limit the size of backups where the volsizelimit parameter actually sets a volume limit. If the user quota is too small then Time Machine will error out at some point before volsizelimit is reached. Mac OS X seems to like the volsizelimit over the user quota setting.

Thanks for this. I'm rather reluctant to use SSH as I'm not yet very familiar with Linux etc. However it's good to know the cause is understood. I presume you've tested and confirmed the fix works in practice?

Are other NAS manufacturers also affected as they were with the previous issue?

Let's hope NetGear can implement this change in the next firmware. Shouldn't be hard for them to come up with a workable solution.

Yes, it fixed my problem.

I'm only familiar with Synology and I do believe they use the same technique of setting a user quota for Time Machine, however I can't say if they are having the same problem as well since I don't have one on hand.

Seemed to work on my 4.1.13 release w/ Snow Leopard O/S but have a point of confusion.

After installing one of the Beta 4.1.13's (T1, T2 or T4 - ?) is when I lost the correct Timemachine allocation.

Typed in the 500000 mb number exactly as in your posting. Went into Frontview and changed the Timemachine allocation to 501,
but my Timemachine application within Snow Leopard shows as available 194.88 GB of 524.29 GB. 524.29 GB Total size ? Would have expected 500 GB or less as total size. Where did the extra 24.29 GB come from ?

Your Mac reports TM space using TB whereas the NAS uses TiB.

500 MiB / 1000^2 * 1024^2 = 524.29 GB

thanks for reporting this issue, we are working on that.

i should have stuck to 4.2.23.

downgrading to 4.2.23 fixed the issue for me....
