[ADSM-L] Why is restore -filelist so much faster?
2011-06-16 15:36:51
For TSM restores that will be from tape, I am discovering that RESTORE
-FILELIST is a whole lot faster for restores of multiple files than
RESTORE <filespec with wildcard>. So I'm building a script to run QUERY
BACKUP and then turn those results into a form for RESTORE -FILELIST.
The performance difference is dramatic - several hours for RESTORE
<filespec> compared to 5-20 minutes for RESTORE -FILELIST. I am
wondering why this is as I exploit this technique.
TSM server 5.5 on AIX, LTO-4 tape.
