Hi all, We're using the standard filesystem backup module (fsdump) and webmin 1.020 to back up our file system on a daily basis (to a magnetic tape drive). I couldn't find any documentation so I need a little help to set up the automated backup process. 1) how do I do only incremental backups? (back up only changed or new files?) 2) can I specifiy that on certain days full backups are done and on certain days incremental ? 3) is it possible to back up files on a remote server? not all our file servers have backup devices, is it possible to back them all up centrally on one drive? thanx!

Yes, but it is tricky. See the man page for the dump command for the details of how backup levels work. That's the command that webmin runs to do the backing up .. > 2) can I specifiy that on certain days full backups are done and on certain > days incremental ? Only by creating multiple backups in the module, each with a different day to run and level. > 3) is it possible to back up files on a remote server? not all our file > servers have backup devices, is it possible to back them all up centrally on > one drive? Yes, using the 'Host' option for the 'Backup to' field. This only works if the remote server has the 'shell' service enabled in inetd or xinetd, which is normally used by the rsh command. You will also need to create a .rhosts file in the home directory of the remote user, containing lines to allow the backup client to connect without a password. Few people use the rsh protocol anymore as it is highly insecure - however, it is the only choice if you are doing remote backups with dump! - Jamie |

Close enough! http://rdiff-backup.stanford.edu/ You'll love it. And it is well documented, so you probably won't have any harder time making it work than dump+rsh+incrementals. Then again, you'll still need something to go to tape (I wouldn't recommend dump, even if it does have a Webmin module). I like Mondorescue so far.
