I am using version 9.1 Windows Server version. Just implementing the backup plan now and running some tests with diffs, pre, post cmds etc. Good so far. Though, I would like to clarify if what I understand is correct. Am backing up from the server to an ext USB drive that's connected to a host pc. This works ok. Its a 200gb drive in the target USB drive and the server's full image backup is about 20GB - this is a full drive image - NOT files and folders. There's no need to backup everyday so the plan is: - 1 weekly full backup. i.e. sunday night - 2 or 3 differentials per week. i.e. Wed and Sat. In this case I WANT the diffs and full backups to be overwritten every week. Just need to capture a week's worth then start over. Will this happen unattended if I schedule it this way? I don't want to have the 2.tib, 3.tib, 4, etc files continue on building in numbers for fear of running out of hard drive space! I don't prefer to have to manually move files around to make room. If this works as expected, maybe I'll use a 2 week window. Or maybe 1 full image per month and 2 or 3 diffs per week - still overwriting the diffs each week, doin 1 full per month. Does this make sense? Am flexible and whichever makes sense and uses less drive space and drive activity. Hardly any changes on the O/S side - why would one do frequent full images? Don't want to create separate files and folders images for data - easier just to grab all with image backup. Thanks - good looking product so far!
