Backup Locking Improvements

[G-i-o]

Is your feature request related to a problem? Please describe it.
With some exceptions, most of the space occupied by the backups comes from the APKs themselves, not from the data.

APKs don't really need to be backed up frequently. Once a month would suffice (maybe with few rare exceptions) as in the worst case scenario, they can be re-downloaded. Data, instead, needs to be backed up daily, at least for some apps as it's unique.

Currently, unless one keeps an infinite or large number of BACKUP REVISIONS, the only way to have a SCHEDULE that backs up APKs, let's say, once a month, and one that backs up data daily is to manually lock each single app APK-only backup.

Describe the primary solution
Include the option to determine both numbers of BACKUP REVISIONS to be retained for UNLOCKED and LOCKED backups.

Describe alternative solutions, if any
Add the LOCK option in the HOME → (context) MENU when selecting multiple apps. This, would allow one to manually backup all apps APKs and lock their backup in few seconds rather tnen having to go through each app.

Thank YOU. 🙏
