Hi, Thanks for this-- I wanted to report that Symantec got back to me after 2 weeks, there is an EEB fix that can be applied on-top of 7.1.x and 7.5.0.4 that will fix this problem. I will test the fix later next week hopefully.
I also need to look into the advice you sent earlier as well, thank you. Justin.

We created a VM with the settings below, copied the data over - yes it took time, but once finished; in one case keep the VM and in another case copied another servers data set back to Bare Metal. It worked. Backups are much better, but more importantly - the restores! http://support.microsoft.com/kb/121007 Scott Jacobson >>> "Justin Piszcz" <[email protected]> 11/28/2012 4:34 AM >>> Hello, Using 7.5.0.3, restoring 1m+ files in a single directory, obviously this would take hours/days (bpdbm just runs forever) to start so what I am doing is splitting it into chunks and that is helping (it works) but was wondering if anyone on this list knows of any special: DIRECTIVES for bpdbm in the bp.conf to optimize/help speed it up for restores? It seems there are some interesting ones: IS_ASCII_CATALOG_FILE_FORMAT SKIP_NOTIFICATION_FOR_UNIT_TEST INSIDE_CATALOG_CLEANUP CLEANUP_KILLED_BY_SIGNAL CATALOG_BACKUP_PARENT_JOBID INSIDE_ASA_BACKUP NB_BPDBM_TEST_DELAY_SOCKET_CLOSE KEEP_EXISTING_DOTF_DURING_IMPORT NB_BPDBM_ALIVE_LOCAL_TIMEOUT There are more as well, does anyone have any tips to improve restore performance of lots of files?
