This commit Closes: #200 .

It adds a note to the recovery section of the documentation manual. This note informs users about the risk of backup obsolescence and deletion during the recovery process, particularly when retention policy rules are enforced, and provides guidance on how to prevent this issue.

Initially, the team considered implementing an automatic solution for this problem. However, several concerns were raised, including the potential for unintended side effects during recovery, the existing keep feature designed to assist with backups, and the need for users to be fully aware of the implications and procedures during recovery—an operation often conducted under stressful situations.

We will need to revisit this.

This implementation is fragile as it is because the WALs required by the recovery process to complete could be vanished once the KEEP is released.

We need to discuss a different approach.

This commit Closes#200. It is adding a note to the recovery
section in the documentation manual alerting the user about
the possibility of the backup getting obsolete while the
recovery process is ongoing and what to do to prevent that.

The team first thought about a solution that could handle this
automatically but many arguments were against this, specially
because it could introduce unwanted behaviour on recover and
the fact that `keep` feature is there to help.
