To locate the client file index save set IDs, use the mminfo command to display
the client file index’s save set ID:
# mminfo -av -N index:cluster_default_alias
where cluster_default_alias is the name of the cluster.
Task 9: Recover the Server’s Client File Index
In this task, you recover the most recent client file index from the last full
backup and all subsequent incremental backups. The client file index contains
detailed information about the backups performed for each NetWorker client.
1. Use the recover command to restore the client file indexes. Recover the
most recent full backup first and then recover the subsequent incremental
backups from earliest to latest. For example, if the dates for the last full
backup and the last two incremental backups are as follows:
• Oct. 15, last full backup
• Oct. 16, second to last incremental backup
• Oct. 17, last incremental backup
then to restore the client file indexes you would enter the following:
# recover -S full_SSID -iY
# recover -S second_last_incremental_SSID -iY
# recover -S last_incremental_SSID -iY
where the _SSID variables are the save set IDs of the last full backup, the
second to last incremental backup, and the last incremental backup,
respectively.
2. Use the nsrim command to cross-check the media database and index
database:
# nsrim -X
3. Use the nsrck command to check and repair the client file indexes if
necessary:
# nsrck -L6
4. Verify that the indexes were recovered properly:
# nsrinfo cluster_default_alias
where cluster_default_alias is the name of the cluster.
