Can someone please explain in detail (the manual is not quite clear) as how the backup image schema works. Here are my questions. Using Secure Zone[/B] 1. I first do a Fullbackup and then on a daily basis incremental backups. 2. If the SZ becomes FULL then as per the manual TI automatically deletes the oldest incremental backup to make room for this new one. The new incremental contains ONLY NEW information since the previous incremental, so by deleting the oldest incremental I do not have a TRUE picture of my disk image, as information is lost. If this is correct, then there is a flaw in this schema. I have no indication that this is happening in the background and that at some stage my backup image is not a true one (full+incremental) 3. When doing a new Full backup image and there is no room then it deletes the old Full backup + all incrementals. This seems OK. Not using Secure Zone 1. I first do a Fullbackup and then on a daily basis incremental backups. 2. In this instance there is no indication as to what TI does when there is no room for incremental backups. 3. When I do a NEW full backup and choose the same name of the OLD Full backup, it does NOT delete the incrementals of the old backup as it does when using Secure Zone. Comments please !!!!!
