Hi list! While regular backup solutions like amanda or bacula are very good at their job, ie keeping point2point copies of the files currently on disk, I find them less suited for archiving - having unused files move to tape in duplo and stay there until requested. I've even read of multi-tier solutions - move to slower disks after a week and further on to tape after a month. Does anyone have some experience or suggestions for this? The project will deal with ~100 TB of growth per year, most files somewhere between 2 and 50 GB. Yes, it can be done with everything in one filesystem, but I'm concerned about running a full backup every month of 500 TB ;-) Not to mention the time required for recovery in case the filesys crashes....
