We are looking at our backup system and disaster recovery strategies. Most modern backup systems now seem to rely on backup images being created rather than backing up on a file by file basis. Although we can see many advantages of backup images when it comes to a fast restore of the server our concern is that if there were a serious problem with the backup image that there is a (very small) possibility that nothing could be retrieved from it. We are considering that in addition to the backup image that we should also back up critical data on a file by file basis, for example the accounts system, database files and selected office files. I would be most interested to hear others opinions on this matter. We are of course going to rotate backup copies from both systems off site.
