List,
I am running pgbackrest 2.52.1 on RHEL 9.4 Postgres 16 for backup to a
remote repository for the last 4 months. All works fine in the initial
months.
Recently the full backup always fails without completing the backup to Repo
Server.
Only differential backup is completing the process as scheduled .
Whenever a full backup is scheduled, after running for hours it fails
with error as in the subject line. Earlier it was working and the last
full backup was completed in April 2026 . Rest of the period differential
backup only completes all full backup processes failed till today.
Yesterday 18 June 2026 at 09:30 AM I ran the full backup from a cron
scheduler explicitly to test, it runs almost 24 hours and today 19 June
10.49 AM it stopped the full backup, Aborted the process.
*What may be the issue ? Any hints are much appreciated. ** Any more
inputs required ? *
Thank you,
Krishane
