Why is my second backup the same size, or close, as the second?
I just downloaded the 2021 version from an Acronis email offer, but have not installed it yet. It reminded me that I have a question regarding my 2020 version.
I recall something being written by Acronis that in 2020, the default backup routine would be something other than incremental, but I paid no attention, because I am a very, very basic user. I back up three drives, with three separate backups, each set as an incremental one with only 2 or three backups in a chain before starting again with a full backup.
I am seeing my backup drive fill up, however, and see the first tib file as the full, but tib001 at exactly the same size or, in one case, slightly less. The data on these drives are not changing much, so I don't understand what is going on.

Thank you for the explanation.
My backup drive is just 1GB, so I need to create settings that allow me to have just the little original file and 2 backups of each drive. Can you suggest what these would be? I clearly made errors. Many thanks!

Philip, I suspect that your backup drive is 1TB not only 1GB...!
What are the sizes of your backups for your 3 different drives?
What automatic cleanup settings do you have set for the backup tasks for these drives?
Please understand that automatic cleanup is only performed after a new Full backup chain has been started, so you need to have sufficient space on your backup drive to store a full backup plus incrementals plus a further full backup for each drive.
For automatic cleanup, I would recommend using the 'Store no more than X recent version chains' option, as this is the simplest and easiest to understand. X should be set to allow for 1 less backup than the maximum capacity of your backup drive.
Example:
X = 2 would require space to store 2 backup chains (2 x Full plus 2 x all Incrementals) plus 1 further Full backup to allow for automatic cleanup to work.

Yes, of course; 1 TB. I have adjusted the settings to 3 incrementals before full, and storing 1 recent version chain. We'll see how that goes and how I may need to adjust.
Thanks much.
