 |

I have several remote sites at the end of slow 1Mbps WAN links. Data sizes are roughly 60GB at each site. Each site has 2 servers, one has the client software and the other has MediaAgent. So I can easily do local data protection backups on site.
What is the best way to get these backups back to our central site? Can I just create another backup set containing the same data as the local backup (and do a remote backup) or is it best to aux copy the local backup to the central site?
No tapes are involved at the remote sites. I just need to get data backed up to our central site as reliably as possible. Speed is not really an issue because the local backup will provide restore capability.

Got a couple of options here….the sites without a MA…use Synthetic Fulls….with the site that has an MA…use SDR(MA replication)

Martin
Stuart or John K can come in and whitebaord this for you using various
methods. Use block level dedupe and synth fulls moves the least amount
of data.

But is it possible to keep the local backup as well as remote? In other words, if I create a new Backupset (for remote backup) with a default subclient containing the same data as the local backupset, will there be a conflict if both use the Change Journal? Considering each backupset will be scheduled at different times. I suppose I could set one to use Change Journal and the other to use Classic File Scan, then they wouldn't step on each others toes.

I'd Aux copy the data to a USB disk first at the remote site, then
overnight the disk to your main server. Once there, use Synthetic
fulls over the WAN link to keep your backups in Sync.

You *hope* the local backup will work. What happens if the entire
site goes down? *grin* The devil is in the details.
This is why I think the USB disk might be the best way to go. 60G
over a 1Mbps link is going to take a long time to do, esp if you need
to keep the link available for production use.
Good luck,
John
