Sorry if this is explained somewhere...I did look through the forums and did RTFM and couldn't specifically find the answer. It may be in forum or manual someplace, if it is, forgive me.
Been using Macrium paid version 6 for personal/home use. I have a laptop with several users and have a daily differential backup plan to back up each user accounts' documents folder to an external HDD set up. Full once a week, then daily differentials. I keep fulls for 4 weeks, current week differentials for 7. I generally keep the machine in sleep mode when not using, and Macrium and Windows Scheduler are set to wake it up. All works great.
Backups work beautifully, only fails when someone disconnects the external and doesn't hook it back up. Anyway, with so much activity on the laptop, there is usually always at least ONE file a day that is added, deleted, or changed, and therefore, when I physically check on backup files on the external, as I tend to do about twice a month (even though I have successful/failure emails sent every day), I am used to seeing 4 full backups and 1 to 7 daily ones, depending on what time of the week I take a peek on the external drive. Here is the thing: over the holidays, we were out of town for an extended period of time and the laptop sat idle for a couple weeks (in sleep mode). Every day just like clockwork I would receive an email stating the backup was successful, albeit no new files detected. However, when I got back from the holidays, and checked the external HDD, I saw only a couple of the full backups that were created (which I expected), but no "current week" differentials.
So my question, after that long back story, is: in the set up I've described, even though Macrium runs the differential every day, if nothing has changed since the last full backup, is a differential backup dataset even created? Even a zero byte one? I looked back at the logs and emails, and they indicated a new file was going to be created, but at the end of the log for each run it notes zero files, etc. So I'm thinking that even though it says it was going to create the next .mrbak, it really doesn't.
Can someone confirm this behavior is true? No differences, no file created? I'm assuming this has happened to me before and I just didn't notice it, only noticing because of the length of time we were gone. If this is normal behavior, that's fine, just trying to understand it.
Thanks for reading,
