Issue

  • A NDMP backup of a volume fails, indicating dump failed to initialize, and that a snapshot copy was deleted
  • Example error message:
This message occurs when a Snapshot(tm) copy in the volume is being deleted to free space. Snapshot copies can be deleted automatically from a volume to enforce the corresponding automatic deletion policy
 
  • If the NetApp /etc/log/backup log is examined, messages similar to this example may be found:
dmp Tue May 10 08:46:46 CDT 2022 [uninitialized](0) Error (could not create "backup" snapshot.snapshot deleted after creation?)
dmp Tue May 10 08:46:46 CDT 2022 [uninitialized](0) Error (Dump failed to initialize.)
dmp Tue May 10 08:46:46 CDT 2022 [uninitialized](0) Abort (0 MB, 36969450 secs, 0 MBps)
dmp Tue May 10 08:46:46 CDT 2022 [uninitialized](0) Error (DUMP IS ABORTED)
dmp Tue May 10 08:46:46 CDT 2022 [uninitialized](0) Error (deletion of "/vol/[vol name]/../snapshot_for_backup.1243" sna
pshot failed: No such file or directory)
 
  • As the snapshot_for_backup is being deleted during backup, dump is unable to initialize, and the backup job is aborted
