Sounds like a fairly small server.

Well, if you want just before the crash, you need some kind of mirroring or raid that makes a recoverable copy or stripe of your data. Backups will only restore from the point of the backup. I would suggest mirroring combined with frequent backups - daily. As for the medium, it depends on how much backup you need. Do you need long term archive copies - then use tape. If you only need to restore a recent backup after some catastrophic failure, then probably backing up to a large USB disk would be fine. Use dump/restore to do the backups. Organize your file systems so that stuff that never or rarely changes does not go in to your daily backup and by size so that if possible, one file system can fit on a single recording media - eg tape or disk or whatever. It is possible to have continuation media, but it is nice if you don't have to. ////jerry > > pls share your expertise , it will help me lot to secure my data in the > server machine .. > > Thanks in Advance > KK > > _________________________________________________________________ > Live the life in style with MSN Lifestyle.
