So, instead we mounted the backup volumes on the servers, and the end users (most of them being developers & graphic designers) could have direct access to their backups. Currently we mount the SMB share over SSH, then rsync to it: ssh -f -N -L 139:usabackup01:139 softdux at usabackup01 mount -t cifs //localhost/backups /bck/ -o username=xxxxxx,password=xxxxxxx rsync -avz /home/pete/* /bck/home/pete/ ^ this is just a quick sample. The different control panels use rsync differently, and some users have their own rsync scripts as well. But, I don't know if this is optimal. i.e. are other protocols which will work better, and I could only think of iSCSI & NFS, but I don't know if they're any better. -- Kind Regards Rudi Ahlers SoftDux Website: http://www.SoftDux.com Technical Blog: http://Blog.SoftDux.com Office: 087 805 9573 Cell: 082 554 7532 -------------- next part -------------- An HTML attachment was scrubbed...
