[ADSM-L] Large disk concerns/alternatives ?
2009-08-24 12:55:01
Good day everyone,
I'm looking for some workable suggestions for larger lun backups.
I'm talking 1.5tb and larger lun sizes. I have a number of remote sites that
have large quantities of hi-res image files and they need an offsite backup
solution. Usually we are notified before the disks go into production and the
backups grow as the disk is populated.
Normally not a big deal. Now we are in the middle of a large conversion for
many remote sites which will require a full backup for all of the sites. And
each has in excess of 6 tb of images. In addition we are also migrating a
number of rogue sites to TSM which also have in excess of 4tb locally.
I tried a test and ran one disk as a full over a 1gb pipe to 2tb of TSM
diskpool on Sata disks. It has been running for 3 days. Not only is it not
acceptable in a real DR scenario (Currently we restore to the same site as the
TSM server then move data back in order of importance),but, it will also take
weeks before I can safely say we are back to being fully backed up.
Other than local backups for each site... has anybody come across a similar
scenario and care to offer some advice.
Some specifics: I have 3 TSM servers (AIX) with either a L700 or a T950
library. No data is backed up locally. All data is sent over the network to a
remote TSM server.
Thanks,
Duane
