Hi there Try the following:
- install and configure multiple TSM Journal Instances for different parts of the file system - run multiple concurrent backup jobs - run /incrbydate backups during the weeknights, combined with normal incrementals on weekends -----Original Message----- From: ADSM: Dist Stor Manager [mailto:[email protected]] On Behalf Of Mehdi Salehi Sent: Thursday, 30 April 2009 1:58 PM To: [email protected] Subject: [ADSM-L] best backup method for millions of small files? Hi, There is an NTFS filesystem in windows with 20 millions of small files less than 20 KB each. The total size of the filesystem is less than 300GB. I have not tried incremental backup, because that would be a nightmare. Again, inc backup is not a good choice because the long restoration time is not acceptable us. I tested the snapshot image backup and satisfied with backup time. Now the problem is how to perform the incremental for this image backup. Unfortunately "incremental-by-date of last image" scans the whole files to filter which files must be in the backup list and would take a tremendous amount of time. This is not acceptable as well. The ideal behavior that I expect from TSM is journal based incremental backup for image which is apparently not supported by TSM 5.3. more info: -the change rate for this filesystem is about 20 thousands of files per day -TSM version is 5.3 What do you recommend for this case? Please include TSM 6.1 featues if exist.
