Configuring NSR-ORA

NETAPP_SNAP_NR=[0-30]:[0-30]:[0-30]

This parameter defines the type of and number of snapshot backups to be kept for a restore process. NetWorker uses three types of snapshots: snapshot-by-week (first value), snapshots-by-day (second value) and snapshot-by-hour (third value). The sum of all three values must not exceed the value 30. NetWorker names the snapshot files automatically using the following scheme:

nsrora_<ORACLE-SID>_<mode>.<n>

The type names of the snapshots do not describe the retention time the relevant snapshot files are kept by NetWorker not the cycle when the backup is performed.

–The last “n” snapshots are called “snapshots-by-hour”. They may have been created on several different days. If, for example, the value for this type of snapshots is set to “10” and NetWorker generates a snapshot every six hours, then the ten snapshots-by-hour kept by NetWorker date from three different days. With every new snapshot-backup of the database all the existing snapshots-by-hour are renamed. Therefore the oldest snapshot will either be deleted (if the number of existing snapshot files exceeds the defined maximum number of snapshots to be kept) or will be renamed to a snapshot-by-day (see example).

–The snapshots-by-day are “older” snapshots-by-hour, which have been set and renamed to this type of snapshot. A snapshot-by-hour is renamed to a snapshot-by-day if it is the last backup on a day. Whenever NetWorker generates a new snapshot-by-day the existing snapshots-by- day are renamed using a higher counter. Thus the oldest snapshot will either be deleted (if the number of existing snapshot files exceeds the defined maximum number of snapshots to be kept) or will be renamed to a snapshot-by-week (see example).

–The snapshots-by-week are former snapshots-by-day which were generated on the last day of a week. If a snapshot-by-day is to be deleted, NSR-ORA checks, wether it has been created on the last day of a week as defined by the LAST_WEEK_DAY parameter (see below). Thus this snapshot becomes a snapshot-by-week. The oldest snapshot will be deleted (if the number of existing snapshot files exceeds the defined maximum number of snapshots to be kept) and all the other snapshots- by-week to be kept by NetWorker are renamed using a higher counter (see example).
