NSR_POOL(5)							   NSR_POOL(5)

       nsr_pool - NetWorker resource type ``NSR pool''

       type: NSR pool

       Each  NSR  pool is described by a single resource of type NSR pool (see
       nsr_resource(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, for  example,
       Group  or  Level,  of the save.	Consult your NetWorker Administrator's
       Guide for more guidelines on using pools.

       There are six types of pools.  Backup pools accept  data	 from  savegrp
       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 an archive clone pool. Similiarly, PC Ar‐
       chive pools accept PC archive data. Also, PC archive data can be cloned
       to a PC Archive Clone pool.

       There  are  ten	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 Indexed Archive	 pool.
       While Archive pool is the counterpart of Indexed Archive pool that does
       not store index entries.	 When cloning data, the	 user  must  select  a
       destination  pool  for the operation.  The Default clone pool is avail‐
       able for users to clone backup data to.	 Both  Indexed	Archive	 clone
       pool  and  Archive  clone pool are available for users to clone archive
       data to, with Indexed Archive clone pool designed for  users  to	 clone
       indexed	archives  and  Archive	clone  pool  designed for cloning non-
       indexed archives. The PC Archive pool is designed for  the  PC  archive
       data,  whereas  the PC Archive Clone is available for users to clone PC
       archive data to. Similarly, the Migration and Migration Clone pools are
       designed for migration data and cloning of migration data respectively.

       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, for example, fulls versus incremen‐
       tals.  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 gen‐
       erated without index entries can still be recovered  using  the	``Save
       Set Recover'' feature of nwrecover (8) or recover(8).

       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 inter‐
       est only to programs or experts, and these attributes can only be  seen
       when the hidden option is turned on in nsradmin(8).

       comment	      (read/write)
	      This  attribute  is  provided  for the administrator to keep any
	      explanatory remarks or supplementary information about the pool.

       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;

       auto media verify   (read/write, yes/no, choice)
	      If  set  to yes, NetWorker verifies data written to volumes from
	      this pool.  Data is verified by  re-positioning  the  volume  to
	      read  a  portion of the data previously written to the media and
	      comparing the data read to the original data  written.   If  the
	      data  read matches the data written, verification succeeds; oth‐
	      erwise it fails.	Media is verified whenever  a  volume  becomes
	      full  while  saving and it is necessary to continue onto another
	      volume, or when a volume goes idle because all save  sets	 being
	      written to the volume are complete.  When a volume fails verifi‐
	      cation, it is marked full so NetWorker will not select the  vol‐
	      ume for future saves.  The volume remains full until it is recy‐
	      cled or a user marks it not full.	 If a volume  fails  verifica‐
	      tion  while  attempting to switch volumes, all save sets writing
	      to the volume are terminated.
	      Example: auto media verify: yes;

       clients	 (read/write, choice)
	      What clients (nsr_client(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;

       devices	 (read/write, choice)
	      This attribute lists the ONLY devices  that  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/nrst8;

       groups	 (read/write, choice)
	      What groups (nsr_group(5)) are allowed in this pool.
	      Example: groups: Accounting;

       label template (read/write, choice)
	      Determine what label template (nsr_label(5)) is referenced  when
	      generating volume names for this pool.
	      Example: label template: Accounting;

       levels	 (read/write, choice)
	      What levels (nsr_schedule(5)) are allowed in this pool.
	      Example: levels: full;

       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	 be  chosen at the administrator's convenience, but it
	      must be unique for this NetWorker server.	  The  pool  resources
	      named  Default,  Default Clone, Indexed Archive, Indexed Archive
	      Clone, Archive, Archive Clone, PC Archive, and PC Archive	 Clone
	      cannot be modified or deleted.  The pool resource named Full and
	      NonFull cannot be deleted.  Other pools can only be  deleted  if
	      no volumes still reference them.
	      Example: name: Accounting;

       recycle from other pools	 (read/write, yes/no, choice)
	      This  attribute determines whether or not a given pool can recy‐
	      cle volumes from other pools when it exhausts all its write-able
	      and recyclable volumes.
	      Example: recycle from other pools: yes;

       recycle to other pools (read/write, yes/no, choice)
	      This  attribute  determines  whether  or not a given pool allows
	      other pools to  recycle its recyclable volume for their use.
	      Example: recycle to other pools: yes;

       retention policy	       (read/write, choice)
	      This attribute specifies the name of the policy controlling  how
	      long  entries  will  remain  in  the media index before they are
	      marked as recyclable.  The default value is blank meaning	 there
	      is  no  pool  policy. In the absense of a pool policy the client
	      policy is used to determine the  save  set  expiration  date.  A
	      defined pool policy is always considered if it is a not the only
	      instance of the save set (a clone). The pool policy  is  consid‐
	      ered  for	 original save sets but is utilized only if the period
	      defined by the policy is longer the  retention  policy's	period
	      defined by the client resource, see nsr_policy(5).
	      Example: retention policy: Year;

       save sets	      (read/write, choice)
	      What  save  sets (nsr_client(5)) are allowed in this pool.  Save
	      sets can be matched using the regular expression matching	 algo‐
	      rithm described in nsr_regexp(5)).
	      Example: save sets: /, /usr, C:\\windows\\system, *.JPG ;

       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  vol‐
	      ume 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 modi‐
	      fied by a user.
	      Example: status: enabled;

       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;

       volume type preference (read/write, choice)
	      This attribute is used as a selection factor when a  request  is
	      made  for	 a write-able volume.  The preferred type will be con‐
	      sidered first within a priority level such as jukebox  or	 stand
	      alone device .
	      Example: volume type preference: 4mm;

       max parallelism (read/write, hidden)
	      This attribute can be used to impose an upper limit for the num‐
	      ber of parallel sessions saving to  a  media  belonging  to  the
	      pool.  Fewer  parallel save session written to media reduces the
	      time required to recover data from  a  saveset.  Value  of  zero
	      imposes  no limit on number of parallel save sessions written to
	      media belonging to this pool.

       mount class	      (read/write)
	      This attribute is kept for historical reasons only.  It  has  no
