System Administrator’s Guide U42252-J-Z915-1-76
NSR-ORA and NetApp Configuring NSR-ORA Using the snap list command the administrator can obtain information about the number and the dates of creation of the existing snapshots.Example:

NETAPP_SNAP_NR=2:5:5

With this command, NetWorker will perform a level-1-backup every four hours and will additionally run a backup with the level full at 23.00 h every day. If the parameter NETAPP_SNAP_NR is set as above NetWorker will keep two snapshots-by-week, five snapshots-by-day and also five snapshots-by-hour. The following figure shows the backup cycle resulting from these settings.The snapshots marked with black symbols are newly created at the respective point in time (e.g. 16.00 h). The snapshots with icons filled with dark-gray are files from the previous backup run (e.g. for the 16.00 h backup this is the backup started at 12.00 h), which have been renamed. The snapshots marked with light-gray filled symbols are not only renamed but also changed their type (e.g. from “hour” to “day”). Depending on the rate of change of the database to be backed up the NETAPP_SNAP_NR parameter provides an optimized adjustment of the database snapshots to be saved. If the data and state of your
