I think you can use journalling.
My copy of the TSM 5.3 WindowsBackup-Archive Clients Installation and
User’s Guide has an appendix C describing how to configure the Journal
service. You also need to look at appendix B for the dsmcutil command, or
use the GUI wizard.

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.
Regards,
Mehdi Salehi
