Only that you won't have reliable backups in your central office during that time :-( well, maybe clustered bacula servers might be helpful here, if those ever get implemented ;) currently your best bet probably is to use rsync at some point, which would work nicely for syncing. Yup. I'd do that like this: Set up an SD on the home workers computers. Send their backups to the local SD only. Set up the local SDs to write only small files. Use rsync to sync these volumes to your central backup server. As there are only small files, the overhead for rsync shouldn't be too bad. Or maybe: Setup local SDs on the home office computers with a FileStorage type device writing to NFS shares on the central server over a VPN connection. Setup local SDs to write only small volumes (files). Turn on data spooling so that the local SDs spool to local disk before writing to the NFS share on the central server. Restores would then use an NFS share on the central server and would not require any additional effort. However, rsync might be more robust than using NFS over VPN with an ADSL connection. As Arno points out, there are many possibilities. One must weigh cost vs. performance vs. reliability and etc. Or rsync your whole computers to your central office and backup from there. Restores would then need additional effort. Has anybody a solution for that problem? This is adifficult setup. I don't think a perfect solution is possible - my work-around from above, for example, requires extra work if you need to restore from the centrally located volumes (importing the volmes into the catalog). Another possible solution might be to take a full backup after you set up the home computers in your central facilities and only run incremental or differential backups when the machines ore off-site. This leaves a certain amount of unreliability, because you might miss files (especially relocated ones) in your backups. You could also set up a local SD at the home offices which would be used for full backups to a removable hard disk which would then be mailed to you. Or get a better network to your home offices :-) Hmm, there are many possibilities, it seems. Which one fits your needs best is difficult to decide without more detailed information, I guess.
