Lost trying to create a backup that overwrites the one created 2 backups before (1, then 2, then 3 overwrites 1).
I have tried to solve this many ways, and so far, none have worked.
I have an external 6TB drive that is my backup drive. I want backup specific folders to it (1 backup, every 2 weeks, and have week 3 backup, overwrite week 1). So at any given time, I only have 2 backups (which are about 2TB. What I keep getting is a full backup, then incrementals until the drive is full. Then of course, an error, and backups stop. I used to do this at my old job with a tape drive for our servers. But that was a very old version of Acronis, and many years ago. The new interface completely different, so I am at a loss on how to do that again. Any help would be greatly appreciated.
Thanks

Don, the simplest & easiest option to use & understand is to ‘Store no more than X recent versions / version chains.’ The criteria here means that if you set X = 2, then when the X+1 (3rd) version / version chain is created successfully with a new Full backup file, then the oldest version / version chain will be deleted by automatic cleanup.
Example:
Incremental backup task, using Full plus 5 Incremental backups before next new Full backup.
Task scheduled to run daily with automatic cleanup set to ‘Store no more than 2 version chains.’
Day 1 – Full backup created.
Days 2 – 6 Incremental backups created.
Day 7 – Next new Full backup created.
Days 8 – 12 Incremental backups created.
Day 13 – Next new Full backup created. Automatic cleanup deletes files created on days 1 – 6.

I understand what you both are doing.
This was what I 'was' trying to do:
------------
Day 1 – Full backup created.
Days 2 – 6 Incremental backups created.
Day 7 – Next new Full backup created.
Days 8 – 12 Incremental backups created.
Day 13 – Next new Full backup created. Automatic cleanup deletes files created on days 1 – 6.
And I wasn't aware of the cleanup on page 58. Thanks to both of you. now I can get back some sense of relief.
Fyi, my full backup was a little over 1TB, and I don't feel, from the incrementals I was seeing, that 2 backups and the incrementals would come close to filling my 6TB drive up.
I will set this up and let both of you know how well I did, (I.E. how well I followed your instructions, lol).
Thank you!
