NSR_POOL(5) Legato NetWorker 4.1.1 NSR_POOL(5)
NAME
NSR pool - NetWorker resource type ``NSR pool''
SYNOPSIS
type: NSR pool
DESCRIPTION
Each NSR pool is described by a single resource of type NSR pool (see
nsrresource(5)). To edit the NSR pool resources for a NetWorker
server type:
nsradmin -c "type:NSR pool"
Be careful to include the quotes and the space between ``NSR'' and
``pool''. See the nsradmin(8) manual page for more information on
using the NetWorker administration program.
These resources are used by NetWorker to determine what volumes save
sets should reside on depending upon the characteristics, e.g. Group
or Level, of the save. Consult your NetWorker Administration Guide
for more guidelines on using pools.
There are four types of pools. Backup pools accept data from
savegroup and manual backups. Archive pools accept archive data.
Data cloned from a backup pool can be directed to a backup clone
pool. Likewise, archive data can be cloned to a archive clone pool.
There are four pools shipped pre-enabled with NetWorker. The Default
pool is meant to collect any backup data not directed to a pool a
user creates with selection criteria. Any archive data not directed
to a pool with selection criteria is collected in the Archive pool.
When cloning data, the user must select a destination pool for the
operation. The Default clone pool is available for users to clone
backup data to. The Archive clone pool is available for users to
clone archive data to.
There are also a few pools shipped with NetWorker that are not
enabled by default. The Full and NonFull pools can be used to
segregate full level backups from other backups, e.g. fulls versus
incrementals. The Offsite pool can be used to generate offsite
backups, because no index entries are stored for the media pool and
will not be referenced during normal recovers. Note that one can
also clone media to produce copies of data to be taken offsite. Save
sets that are generated without index entries can still be recovered
using ``Save Set Recover'' feature of nwadmin(8) or recover(8).
ATTRIBUTES
The following attributes are defined for resource type NSR pool. The
information in parentheses describes how the attribute values are
accessed. Create-only indicates that the value cannot be changed
after the resource has been created. Read/write means the value can
be updated by authorized administrators. Yes/no means only a yes or
no choice is possible. Choice indicates that the value can only be
selected from a given list. Hidden means it is an attribute of
interest only to programs or experts, and these attributes can only
be seen when the hidden option is turned on in nsradmin(8) or if the

name (create-only)
The names of pool resources are used when labeling volumes and
when determining what volumes a save set should reside on.
The name can generally be chosen at the administrator's
convenience, but it must be unique for this NetWorker server.
The pool resources named Default, Default Clone, Archive, and
Archive Clone may not be modified or deleted. The pool
resource named Full and NonFull may not be deleted. Other
pools can only be deleted if no volumes still reference them.
Example: name: Accounting;
groups (read/write, choice)
What groups (nsrgroup(5)) are allowed in this pool.
Example: groups: Accounting;
clients (read/write, choice)
What clients (nsrclient(5)) are allowed in this pool. If a
group is specified, only clients that are members of that
group are allowed to be listed.
Example: clients: mars;
save sets (read/write, choice)
What save sets (nsrclient(5)) are allowed in this pool.
Example: save sets: /, /usr;
levels (read/write, choice)
What levels (nsrschedule(5)) are allowed in this pool.
Example: levels: full;
archive only (read/write, yes/no, hidden, create)
If yes is selected, only archive saves are allowed to this
pool. This hidden attribute can be modified by a user.
Example: archive only: no;
status (read/write, hidden, choice)
If set to enabled, this pool is considered for determining
what pools a save set should be saved to when performing
backup volume selection. If set to clone, this pool is
considered only as the destination of cloning operations. If
set to disabled, this pool is completely ignored. This hidden
attribute can be modified by a user.
Example: status: enabled;
label template (read/write, choice)
Determine what label template (nsrlabel(5)) is referenced
when generating volume names for this pool.
Example: label template: Accounting;
devices (read/write, choice)
This attribute lists the ONLY devices volumes from this pool
are allowed to be mounted onto. If no devices are listed,

volumes from this pool may be mounted on any device.
Example: devices: /dev/rmt/8;
store index entries (read/write, yes/no, choice)
If set to yes, entries are made into the file indexes for the
backups. Otherwise, only media database entries for the save
sets are created.
Example: store index entries: yes;
