Contents : NSRIM ( 8 ) Maintenance Procedures NSRIM ( 8 ) NAME nsrim NetWorker index management program SYNOPSIS nsrim c client N saveset x percent lnqvMX DESCRIPTION The nsrim program is used to manage NetWorker s online le and media indexes. Normally nsrim is invoked by nsrmmdbd(8) at startup by the savegrp(8) command on completion and by nsrd(8) when Remove oldest cycle is selected from the NetWorker Administrator program. nsrim is not normally run manually. nsrim uses policies to determine how to manage on-line entries (see nsr policy(5) nsr client(5) and the Legato NetWorker Administrator s Guide for an explanation of index policies). Entries that have been in an on-line le index longer than the period speci ed by the respective client s browse policy are removed. Save sets that have existed longer than the period speci ed by a client s retention policy are marked as recyclable in the media index. When all of the save sets on a volume have been marked recyclable then the volume is considered recyclable. Recyclable volumes may be selected (and automatically relabeled by a jukebox) by NetWorker when a writable volume is needed to hold new backups. When a recyclable volume is re-used the old data is erased and is no longer recoverable. Unless the q option is used nsrim prints header and trailer information for each group of save sets. The header lists the save set type the client name the save set name and the applicable browse and retention policies that apply to the save set (see the example below). There are four types of save sets: Normal includes all save sets backed up automatically using savegrp that are associated with a schedule a browse policy and a retention policy. Ad hocs User initiated save sets are designated by appending ad hocs to the header line. Archives Save sets that never expire automatically are designated by appending archives to the save set line. Migrations Save sets that never expire automatically and were created by a le migration application are designated by appending migrations to the save set line. The trailer lists four utilization statistics of the save set after nsrim has applied the policies to it. The four statistics are the total number of browsable les remaining in the online index the grand total of les currently associated with the save set and the amount of recoverable data out of the grand total of data associated with the save set. For example nsrim may print the following output for a single save set name: mars:/usr retention policy: Year browse policy: Month ad hocs 8481 browsable les of 16481 total 89 MB recoverable of 179 MB total mars:/usr retention policy: Year browse policy: Month ad hocs 0 browsable les of 13896 total 163 MB recoverable of 163 MB total mars:/usr retention policy: Year browse policy: Month 43835 browsable les of 427566 total 6946 MB recoverable of 7114 MB total When the v option is used the following information is also printed for each save set: the save set id creation date level le count size and status. A save set s status is one of the following: browse The le entries for the save set are browsable (the save set les still exist in the online index). These les are easily restored using NetWorker s recover mechanisms. recover The age of the save set s does not exceed its retention policy for the save set but its entries have been purged from NetWorker s online index. This means that save set is recoverable from the back-up media using recover (see recover(8)) scanner(8) may be also be used to recover the save NetWorker 6.0.Build.67 Last change: May 06 2000 1 NSRIM ( 8 ) Maintenance Procedures NSRIM ( 8 ) set but users should utilize recover rst). recycle The save set is older than its associated retention policy and may be overwritten (deleted) once its backup media is recycled. Until the media is recycled the save set is also recoverable from the back-up media. delete The save set will be deleted from the media database. nsrim deletes only recyclable save sets that have zero les. The save set status may be followed by any of the following modi ers: (archive) The save set never expires and is exempt from any status change. (migration) The save set was created by a le migration application and never expires and is exempt from any status change. (scanned in) The save set was restored using the scanner command and is exempt from any status change. (aborted) A save set of questionable size consuming backup media space. If nsrim changes the status of a save set then it prints the transition symbol followed by the new status.
