We recently upgraded a OCUM virtual appliance from version 7.1 to version 7.2P1.
I notice that there seems to be some problem with the scheduled backup job in OCUM. The Web UI shows that it fails because there is not enough disk space. When I look on the system itself, I see the following messages in ocum-error.log:
2017-11-04 01:47:25,156 ERROR [oncommand] [taskScheduler-4] [Backup|ScheduleBackup] [c.n.d.i.backup.BackupRestoreManager] Error while taking incremental backup. Exit code is 1.

The systems /data fielsystem has 55GB free (48% Used). It seems to me that should be enough space for at least a couple of database backups.
The existing backup files in /data/ocum-backup look like this:
8.1M /data/ocum-backup/UM_7.1P1_backup_unix_08-27-2017-01-03.7z 8.3M /data/ocum-backup/UM_7.1P1_backup_unix_09-03-2017-01-03.7z 8.5M /data/ocum-backup/UM_7.1P1_backup_unix_09-10-2017-01-03.7z 8.8M /data/ocum-backup/UM_7.1P1_backup_unix_09-17-2017-01-03.7z 9.0M /data/ocum-backup/UM_7.1P1_backup_unix_09-21-2017-10-04.7z 18G /data/ocum-backup/UM_7.2P1_backup_unix6390741292408362900 74M /data/ocum-backup/UM_7.2P1_backup_unix_09-23-2017-01-03.7z 943M /data/ocum-backup/UM_7.2P1_backup_unix_09-30-2017-01-03.7z 1.8G /data/ocum-backup/UM_7.2P1_backup_unix_10-07-2017-01-03.7z 3.9G /data/ocum-backup/UM_7.2P1_backup_unix_10-28-2017-01-03.7z
Currently the database itself (/data/mysql) is using a total of 20GB.
Does the system really need over 50GB to store a backup? Previous backups seem to be a lot smaller (those from version 7.1 infeasibly so).
Or is the cause of the problem that mysql is returning exit code 1 along with that security warning about using the password on the command line?
