Using Isilon storage as a Time MAchine target for MAC OSX backups
We have a small group ( < 20 ) of macosx users we need to backup :
They are now using time machine, although an alternate backup scheme could work. Are there users out there who have implemented this already?
A linux server based recipe is located here:
Time Machine via NFS on Mavericks | Random Notes on IT Stuff
one puzzler is in the mount option it specifically says ,insecure, : is there an isilon equivalent? It may not be necessary or evean desirable.
The plan is to have individual TimeMachine/UserId/ directories for each user .
Is there a better way to use the isilon for this?
Further information: Isilon OneFS v7.0.2.5 and Mac0SX 10.8 and 10.9

"insecure" allows connections from ports above 1024
The document also suggest "resvport" on the Mac side,
which means ports lower than 1024. Somewhat inconsistent advice.
Mounting will be done as root on the Macs:
How will you prevent users from accessing other users' backups then?
One export per user, "secured" by client IP? not very secure.
In case you backup the Isilon to tape (NDMP), beware
that even after minor changes in a user's backup,
the whole Time Machine image file will to to tape...
You might also consider using rsync or unison,
which create file-by-file replica on the backup side.

I have not tried this with the isilon, but I have had some issues with doing it against linux or FreeBSD running netatalk. Frequently, Time Machine thinks that the backup is corrupt and it needs to be regenerated.
According to a post on Server Fault this is common, and the implication is that in general, roll-your-own-time-machine is flakey.
If I were you, though, I'd just try it out for a while and see how it works. Do frequent test restores.
