rsnapshot, previously mentioned by me and a few others in this thread, is a nice packaged implementation of just what Jack described in the previous post. It uses rsync together with hardlinking to be able to store multiple snapshots of whatever it is you want to backup with only a "delta" more HD space used for each snapshot. It is highly configurable and works like a charm.
For my personal data, I take and save a snapshot of my HD each day (saving the last 5), each week (saving the last 2), each month (saving the last 3). I've never, ever lost a file with this system, and I've deleted several files that I didn't want to (grabbed it from the snapshot backup without incident), as well as survived a HD crash (rsnapshot restored my data easily after HD was replaced). And these are the sizes of the data drive and the BACKUP drive. /dev/sda4 208G 101G 108G 49% /data /dev/sdb1 230G 122G 97G 56% /BACKUP 10 full HD backups for only a small amount more space than the current. Pretty sweet. I also find this a MUCH better solution than RAID, which I find a troubling amount of people using it as 100% of their backup system. RAID's a really cool technology, but that was never what it was intended for... cheers, #!/ben -- bklaas ------------------------------------------------------------------------ bklaas's Profile: http://forums.slimdevices.com/member.php?userid=58 View this thread: http://forums.slimdevices.com/showthread.php?t=22161 _______________________________________________ Discuss mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/discuss
