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. Regards, Mehdi Salehi
