Hi,
We backing up a couple of PB of Isilon daily that generates a couple of 100GB
per day of new data.
We are backing up over NFS but it is very bad solution, and it takes around 24
hours before the Isilon and TSM have identify all new files.
There is a undocumented APIs so you can identify all change files in the Isilon
so you can run a selective backup, but we had a hard time to get hold of them
from EMC because they are not as open as IBM is.
Another way that is not recommended is to use NDMP, LOL good luck with that if
you don't want to spend millions of $$$.
What I try to do now instead is either replace the EMC Isilon with IBM ESS
instead that is much better or try implement GPFS on top of the Isilon so we
get a much better backup functionality. But that is nothing IBM have tried to
get working.

Subject: Re: Backing up Isilons with TSM
Skylar,
Can you give us details on how you setup the Isilon to give a TSM node
authority to back up the individual mount points? My SAN/Isilon guy has tried
setting up a standard TSM node but all attempts at backing up mounted
filesystems blocks him with "access denied" errors. We are very new to Isilon
so any help would be greatly appreciated.
Feel free to email me directly if you want to take this discussion
offline/off-list.
