 Description   

Today I was wondering what happens if I do a:

BACKUP STAGE START
BACKUP STAGE BLOCK_COMMIT

And then an exit. This is a common situation with external backup tools (like Veeam) for doing Snapshots.

Documentation did not state anything about it:
https://mariadb.com/kb/en/storage-snapshots-and-backup-stage-commands/
https://mariadb.com/kb/en/mariabackup-and-backup-stage-commands/
https://mariadb.com/kb/en/backup-stage/

Our own experiments showed that a disconnect automatically releases backup stages. This should possibly be mentioned in the docu?

Further we wanted to see in which one the 5 different backup stages we actually are. I did not find a fast way to find this out. Should possibly also be documented?

Correct, the backup stages are released. There is no easy way to find out which is the current stage. Added notes to https://mariadb.com/kb/en/backup-stage/
