NDMP backup levels
At the start of a debug log, you may see an entry titled LEVEL. This entry refers to an environment variable that NetBackup set based on the type of backup. Here is an example from a bptm log:
08:48:38.816 [22923] <2> write_data_ndmp: backup environment
values:
08:48:38.816 [22923] <2> write_data_ndmp: Environment 1:
TYPE=dump
08:48:38.816 [22923] <2> write_data_ndmp: Environment 2:
FILESYSTEM=/vol/vol0/2million
08:48:38.817 [22923] <2> write_data_ndmp: Environment 3:
PREFIX=/vol/vol0/2million
08:48:38.817 [22923] <2> write_data_ndmp: Environment 4: LEVEL=0The NDMP backup level is modeled after UNIX dump levels. The backup level is a number in the range of 0 to 9.
An NDMP backup level of 0 is a full backup. A backup level greater than 0 is an incremental backup of all objects that were modified since the last backup of a lower level. For example, level 1 is a backup of all objects that were modified since the full backup (level 0). Level 3 is a backup of all objects that were modified since the last level 2 incremental.
Table: NetBackup backup types and corresponding NDMP backup levels
NetBackup backup types | NDMP backup levels |
|---|---|
NetBackup Full | NDMP level 0 |
NetBackup Cumulative Incremental | NDMP level 1 |
NetBackup Differential Incremental | NDMP level (last level + 1, up to 9) Some vendors support level values that are greater than 9. For valid level values for your device, see the NetBackup for NDMP: NAS Appliance Information from the Veritas Support website: |
