The event field for a dump event contains an event type followed by event-specific information within parentheses.
The following table describes the events, their descriptions, and the related event information that might be recorded for a dump operation:
| Event | Description | Event information |

| Start | A dump or NDMP dump is started | Dump level and the type of dump |
| Restart | A dump restarts | Dump level |
| End | Dumps completed successfully | Amount of data processed |
| Abort | The operation is cancelled | Amount of data processed |
| Options | Specified options are listed | All options and their associated values, including NDMP options |
| Tape_open | The tape is open for read/write | The new tape device name |
| Tape_close | The tape is closed for read/write | The tape device name |
| Phase-change | A dump is entering a new processing phase | The new phase name |
| Error | A dump has encountered an unexpected event | Error message |
| Snapshot | A Snapshot copy is created or located | The name and time of the Snapshot copy |
| Base_dump | A base dump entry in the /etc/dumpdates file has been located | The level and time of the base dump (for incremental dumps only) |
The following is an example of the output for a dump operation:
dmp Thu Sep 20 01:11:22 GMT /vol/vol0/(1) Start (Level 0) dmp Thu Sep 20 01:11:22 GMT /vol/vol0/(1) Options (b=63, B=1000000, u) dmp Thu Sep 20 01:11:22 GMT /vol/vol0/(1) Snapshot (snapshot_for_backup.6, Sep 20 01:11:21 GMT) dmp Sep 20 01:11:22 GMT /vol/vol0/(1) Tape_open (nrst0a) dmp Sep 20 01:11:22 GMT /vol/vol0/(1) Phase_change (I) dmp Sep 20 01:11:24 GMT /vol/vol0/(1) Phase_change (II) dmp Sep 20 01:11:24 GMT /vol/vol0/(1) Phase_change (III) dmp Sep 20 01:11:26 GMT /vol/vol0/(1) Phase_change (IV) dmp Sep 20 01:14:19 GMT /vol/vol0/(1) Tape_close (nrst0a) dmp Sep 20 01:14:20 GMT /vol/vol0/(1) Tape_open (nrst0a) dmp Sep 20 01:14:54 GMT /vol/vol0/(1) Phase_change (V) dmp Sep 20 01:14:54 GMT /vol/vol0/(1) Tape_close (nrst0a) dmp Sep 20 01:14:54 GMT /vol/vol0/(1) End (1224 MB)There are five phases in a dump operation (map files, map directories, dump directories, dump files, and dump ACLs).
The log file for a dump operation begins with either a Start or Restart event and ends with either an End or Abort event.
