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
