Found interrupted initial backup. Removing...
Fatal Error: Bad rdiff-backup-data dir on destination side

The rdiff-backup data directory
/ext/backup/home/rdiff-backup-data
exists, but we cannot find a valid current_mirror marker.  You can
avoid this message by removing the rdiff-backup-data directory;
however any data in it will be lost.

Probably this error was caused because the first rdiff-backup session
into a new directory failed.  If this is the case it is safe to delete
the rdiff-backup-data directory because there is no important
information in it.
->8-

After removing rdiff-backup-data I restarted rdiff-backup, and nothing
changed - it slowly eats memory, sometimes stopping for a minute-two,
rarely eating ~3-5 MiB more each second.

I will follow-up for the result of second run.
