Michael, In version 5.3 you can create virtual mappings and backup at the Qtree level that way. Not particularly helpful when you're using version 5.2 I know, but perhaps a move to 5.3 is in order? Iain

Hi,
yes, thats what we wanted, but as I explain in my last mail, my TSM-Admin says that TSM can't backup Qtrees. I can't believe that. Does anybody backup qtree with TSM?
thanks

Hi Michael,
I have not seen the NDMP offering from Tivoli, but if it is anything like that of Legatto I would guess that all you need to do is break your one volume backup into multiple Qtree backup jobs, by specifying the path in your backup job configuration as follows -
from /vol/<volume name>
To /vol/<volume name>/<Qtree 1> /vol/<volume name>/<Qtree 2> /vol/<volume name>/<Qtree 3>
Hope this helps,

Hi,
we (try to) backup our filers 940c(6.5.2R1) with ndmp and IBM Tivoli
(TSM)
5.2<Solaris>. We have various Problems. The greatest Volume we backup is
a
ntfs-Volume with 1TB and several qtrees.At the moment we backup the whole Volume.Performance is very bad (not only on great Volumes, same Perf.-Problem with small volumes AND direct attached to a device AND
using
the dump-command!!)So we wanted to spread the backup, but my Backup-Admin says TSM cannot backup qtrees????
Is anybody out there who has GOOD experience with TSM 5.2 and ndmp? A new request in my company is to backup 7TB, is there a chance to realise this with ndmp. (NearStore is not yet a alternative).
Our filers are via SAN connected to L700-Devices.(IBM-LTO2)
Thanks
Michael
