Our main problem with TSM and ZFS is currently that there seems to be no efficient way to do a disaster restore when the backup resides on tape - due to the large number of filesystems/TSM filespaces. The graphical client (dsmj) does not work at all and with dsmc one has to start a separate restore session for each filespace. This results in a unpractical large number of tape mounts.Hans _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discu ssNot sure I quite follow...

I can select mutlipes... I'm assuming as long as the ZFS filesystems are there everything would restore properly... I've got an e-mail into our TSM admin to see if the "restore" has been tested yet... (We're still in the testing phase... LOL)
We tried to restore 3TB from about 1500 TSM filespaces. dsmj does simply hang after a while without restoring anything. According to the IBM support dsmj is not suitable for large data restores and pointed us to dsmc. Hans
