Re: Looking for suggestions to deal with large backups not completing in 24-hours
We've implemented file count quotas in addition to our existing byte quotas to try to avoid this situation. You can improve some things (metadata on SSDs, maybe get an accelerator node if Isilon still offers those) but the fact is that metadata is expensive in terms of CPU (both client and server) and disk. We chose 1 million objects/TB of allocated disk space. We sort of compete with a storage system offered by our central IT organization, and picked a limit higher than what they would provide. To be honest, though, we're retiring our Isilon systems because the performance/scalability/cost ratios just aren't as great as they used to be. Our new storage is GPFS and mmbackup works much better with huge number of files, though it's still not great. In particular, the filelist generation is based around UNIX sort which is definitely a memory pig, though it can be split across multiple systems so can scale out pretty well.

Re: Looking for suggestions to deal with large backups not completing in 24-hours
Zoltan I kind of agree with Ung Yi What is the purpose of your TSM backups? DR? Long term retention for auditability/sarbox/other regulation? It may well be that a daily or even more frequent snapshot regime might be the best way to get back that recently lost/deleted/corrupted file. Use a TSM backup of a weekly point-of-consistency snapshot as your long term strategy. Of course a better option would be an embedded TSM client on the Isilon itself, but the commercial realities are that will never happen.

Looking for suggestions to deal with large backups not completing in 24-hours
As I have mentioned in the past, we have gone through large migrations to DFS based storage on EMC ISILON hardware. As you may recall, we backup these DFS mounts (about 90 at last count) using multiple Windows servers that run multiple ISP nodes (about 30-each) and they access each DFS mount/filesystem via -object=\\rams.adp.vcu.edu\departmentname. This has lead to lots of performance issue with backups and some departments are now complain that their backups are running into multiple-days in some cases. One such case in a department with 2-nodes with over 30-million objects for each node. In the past, their backups were able to finish quicker since they were accessed via dedicated servers and were able to use Journaling to reduce the scan times.
