Table: Informix ON-Bar backup types
Backup type | Description |
|---|
Level 0 backup (Full)
| An Informix level 0 backup is a full backup. It includes all the records in the selected dbspaces and is the only type of backup that allows a complete restore without performing any recovery steps.
|
Level 1 backup (Incremental)
| An Informix level 1 backup is an incremental backup. It backs up the records that changed since the last level 0 backup in the selected dbspaces.
|
Level 2 backup
| An Informix level 2 backup backs up the records that changed since the last Level 1 Backup in the selected dbspaces. NetBackup does not support this type of backup with an equivalent automatic schedule. To perform level 2 backups write a script and by keep track of the previous backup type with the ON-Bar script.
|
Logical-log backup
| An Informix logical-log backup backs up the filled logical logs. By using the Informix ALARMPROGRAM configuration option, these backups can be started on demand when the logical logs fill.
