Folks - We are looking for some backup solutions for a Linux based file server. Up until now we have been burning DVD's, but as the volume of files grows that is becoming a less manageable solution. In general we are talking about amounts of up to 20Gb per backed up volume with about half a

How about the following approach: 1. Full back up to DVD's once per 3-6 months. This will be for archival purposes. 2. Between those DVD backups, back up to hard disks. From your data you need to back up about 120GB per full backup (weekly backup). In 6 months (26 weeks), total backup volume is

Sorry for the interuption, the backup discussion got me thinking. A long time ago someone on this list was looking for blank DAT tapes. I offered him some but had no way to get them to Rehovot where he was and he had no way to get them from Jerusalem where I live. A friend of mine now works at
