Backup Device Reply #25 – 2004-08-16 21:37:52 I use an offline HD.About once a month, I plug it in, backup all the data again. Sometimes I completely delete it first from the backup. Anyway, I always browse through it from some time just after the backup in order to ensure that it works.I don't see any egg problem. If the drive gets broken, I buy another one, and backup again. I can see if it gets broken every month. I wouldn't check DVD or CDR as often as that.Considering how my CDRs behaved, I would have lost at least 30 % of what I've got if I did backup it on them. The CDRs failed no more than one year from each other, depending on the locations. In many cases, I would have lost both the files and the recovery files in all locations, unless I get them all back at home every three monthes in order to check them all.In my opinion, the point is not what media, the point is how you handle your backup. ANY media will fail you if you store it somewhere and forget about it (exept maybe vinyl records). If you care about your data, check the backups regularly. For example, in the supermarkets for which I work, a full backup of the server is done every day and stored off line. All that people has to do, every day, is putting the DDS tape of the day in the player, and store the one inside the drive (from the day before) in its case.
