PgBackRest fails due to filesystem full - Mailing list pgsql-general

List, 

 I am running PgbackRest-2.52.1 on RHEL9.3  and  EDB16  to backup to a remote repo server .   Everything was working fine and backups were regularly taken  with  cron scheduler daily.  

 But due to a   /  partition full 100 % utilization, the pgbackrest  backup failed the other day.  I came to know the backup script is not working for the backup which is scheduled daily from a cron scheduler.  I made  space in  /  file system by removing few  log files  from /var/pgbackrest/DBCluster1 

I tried to  reschedule the backup script (after deleting some log files from  /var and now / is having 50 % free space ) but after running for 2 or 3 minutes pgbackrest fails as follows. 

[root@dbtest log]# sudo -u postgres pgbackrest --stanza=DBCluster1_Repo --type=full backup

  This may be due to the WAL segment from the DB server being unable to sync that time when the file system was full at the Repo Server side which was observed by me after 2 days !!

Any hints how can I rectify this issue and put pgbackrest working back ?? 

How can I  enforce  the consistency of the Backups and WAL files since there may be missing WAL files in between when the RepoServer file system is full ?

Thanks in advance
