In order for such a problem to be fixed it needs to be
- Either reproduced by a developer. This needs detailed steps to get into the situation where the archiving doesn’t work (with exact values to enter). Upgrading from an old version complicates this, because this would have to be included in the reproduction steps (if necessary)
- Debug level log files – see Having problems with UrBackup? Please read before posting . Maybe there are some hints about the issue in the debug level log file
- Database of the misbehaving server . In this case this would be
backup_server.dbandbackup_server_settings.db. That, together with version information would directly let a develoepr have a server in the state where archiving does not work.
A unreleased fix in this area is that image backup archving might not work if the letters are set to no all ( Fix iteration over letters to archive · uroni/urbackup_backend@1ea7946 · GitHub ).
