Have I got my Macrium differentials right?
I have a file that I have set up to be backed up Full once per week, with 4 Differential backups during the week. The Full and the Diffs are set to be retained (I assume for that week). Please see the attachment.
This obviously means that there will be a Full backup every week. But what about the 4 Differentials. I know what a Diff. is but I don't understand what Retaining 4 Diffs means. Does it mean:
1. During the week there will be four Diffs made at equal intervals of 1.75 days (7/4 = 1.75).
2. The first Diff. will record all the changes since the Full backup was made; the second will also record all the changes since the Full was made and so on.
3. At the end of a normal week the Full and the Diffs would be deleted and a new Full immediately created, with the new Diffs created in turn during that new week.
4. If during the week a crash occured and the computer was re-booted, the last Diff created before the crash would be double-clicked on and the Full backup would be updated to the time/date of that last Diff.
5. That updated Full Backup could then be used to restore the computer to the position it was in when the last Diff.was created.
6. This is the reason for creating Diffs. and the only reason.
Have I got this right?
Thanks.
