I have automatic backups setup that is written to 2 different harddrives. There is one full backup and incremental backups runs every week. And one copy of the backup on both harddrives.
As Michael says, the first thing to make sure is that you have more than one backup and these are stored on different hard drives. But since you have ordered two drives it sounds like you have already thought about this. The best solution is also if you are able to store these drives at different places. Two hard drives within the same computer could easily both crash if you get some heat problems. Two drives within the same building could easily both be destroyed in case of a fire in the house, but handling that might be starting to be a bit paranoid. Its also a good idea to keep several copies of a changed file, so you can go back to a previous version. What file format are you using for your music ? FLAC and MP3 are compressed formats so they probably have some internal checksum which you should be able to check against. The flac tool on Linux has a -t flag that does some test, I'm not sure its the correct type of test though. The mp3-decoder tool on Linux also have a -t flag that does some testing. I guess both these probably fails if run on a corrupt file. Another solution is to just store MD5 checksum of all music files and compare these during the backup process. It would report errors for files with changed checksums, this could be intentionally changed files but also modified files. I don't know if there are any solutions ready to use around these tools of if you would have to write the scripts around them yourself. norderney;174898 Wrote: > It took me many months to get all my music ripped to the hard drive, and > I do not want to have to do it again - ever!!!It took me a about a week for > my pretty small collection of about 3000 tracks, but I still don't want to do it again so I can see your point. Hard drives do crash, its just a matter of time. I have already had two crashes, for one I didn't have any backup but fortunately the drive didn't contain any important stuff. The other one did have a lot of important stuff and I hadn't any backup on all digital photos because I thought it took to much space. Fortunately the drive didn't totally crash so I was able to get back everything from either the drive or the backups I had. After this I started to do backups on everything and I also started to do backups to two different drives. -- erland Erland Isaksson 'My homepage' (http://erland.homeip.net) 'My download page' (http://erland.homeip.net/download) (Developer of TrackStat, SQLPlayList, DynamicPlayList, Custom Browse, Custom Scan, Custom Skip, Multi Library and RandomPlayList plugins) ------------------------------------------------------------------------ erland's Profile: http://forums.slimdevices.com/member.php?userid=3124 View this thread: http://forums.slimdevices.com/showthread.php?t=32163 _______________________________________________ discuss mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/discuss
