Backupper - Backup scheme
backupper has several backup scheme but may be interesting adding other two option that can provide simpler backup rotation and less space usage.
The first scheme can be named as forever incremental where, at retention approaching, oldest incremental are merged into the full, and new incremental has been created.
Full Inc1 Inc2 Inc3 --------Full+Inc1 Inc2 Inc3 Inc4
In this way I'll never need space to create another full backup and I have always the desired retention
Second scheme can be named as Reversed incremental where, after the first full, instead creating incremental backup, the change are injected directly into the full, saving the previous data into a reverse incremental file.
In this way, as before, I continue to doesn't need space for a second full backup and, latest restore point are always the full
Full -------- RInc1 Full ------- Rinc1 Rinc2 Full -----Rinc1 Rinc2 Rinc3 Full
I hope you find this interesting feature.
