Problem Description

When FTP, S3, or Azure is used as a backend for database backups, incremental backups may hang immediately after starting the backup. This in turn leads to a hangup of the database itself, rendering it inoperable.

Restarting the database fixes the immediate problem but also aborts the backup process.

Workaround

Full backups (level 0) are not affected, so disabling or reconfiguring the increments eliminates the problem.
