Any backup staggered rotation scheme (different pools & retentions) requires at least \
two version of the same backup level (IMHO). While the last job is resting, you run a \
new one. E.g. monthly backups should have at least 60 days \
retentions.
Btw: you can still restore expired backups, at least until they are recycled.
