What is the best offsite backup to disk solution?

My backup server is 16TB
My full weekly backup is 5TB
My daily incremental is 100GB

Currently the backup server is on site on a 1Gb network. It will be moved off site when ready. When offsite it will still be on my network at 100Mb.

Obviously keeping traffic across the 100Mb line to a minimum is essential.

Any input would be great.

Hopefully I won't have to QoS the line as backups can go up at full speed over night.

I tried CPS it mirrors the files then takes volume shadow copies. It doesn't compress anything and although it can backup a file as soon as it changes, it does not keep a copy of the previous version. It only keeps the shadow copies.

I'm giving Backup Exec Synthetic Backup a go. However I'm having hardware issues so things are moving slowly.

If you're wanting to limit traffic, best recommendation I can figure right off the top of my head is using a router on the Gbit network end of the 100MB connection to QoS the traffic to the backup server. Then you could let the backup server maintain what it's doing and keep it's traffic from the Gbit network down to 10Mb/s or whatever you choose.

You could also look into software suites that do constant synchronization type backups such as the Symantec Continuous Protection Server software. This will spread out the traffic across the day but you will still hit bursts of high utilization as the CPS box is pulling data from the Gbit network.
