Backup method that doesn't require multiple full backups

Thread needs solution

Is there a way to configure a backup job to re-use a single full backup. Basically I want to avoid having to at least double the storage required for my data set in the backup destination. A simple incremental backup is sufficient for my need however I would like to limit the number of incremental versions generated.

Basically a scheme that merges the oldest incremental into the full backup before creating a new incremental.

Chain
F->i1->i2->i3->i4->i5

Next backup keeping only 5 incremental versions
F (F is now merged with i1)->i2->i3->i4->i5->i6

Is there any configuration that would allow limiting the incremental history without having to create an additional full backup? The primary concern is not having to generate multiple full backups.

Nick, welcome to these public User Forums.

The only backup scheme that goes anywhere near to what you are asking is when backing up to the Acronis Cloud which requires an annual subscription for the amount of storage needed.

Otherwise, sorry but no scheme does as you are asking for.
