Duane, You may find worthy to take a look at LAN-Free backups configurations. This would not only alleviate the load on your bandwidth but also decrease the backup duration.
That may or may not work for you but wouldn't hurt to look into it. Good luck.

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 IMPORTANT: E-mail sent through the Internet is not secure.
