Cumulative-Incremental Backup
When the NetBackup master server is configured to perform a cumulative-incremental
backup, NetBackup backs up all files that have changed since the last successful full
backup.
Cumulative-incremental backups can be configured to use either the datetime stamp or
the archive bit. If the datetime stamp is used, the cumulative-incremental backup includes
all files with a datetime stamp that is more recent than the last full backup. If the archive
bit is used, the cumulative-incremental backup includes all files that have their archive bit
set. Archive bits are not cleared on cumulative-incrementals. Refer to “General Tab” on
page 62 for more details on performing incremental backups with archive bits.
