VGCFGBACKUP(8)							VGCFGBACKUP(8)

NAME
       vgcfgbackup - Backup volume group configuration(s)

SYNOPSIS
       vgcfgbackup
	   [ option_args ]
	   [ position_args ]

DESCRIPTION
       vgcfgbackup  creates  back  up files containing metadata of VGs.	 If no
       VGs are named, back up files are created for all VGs.  See vgcfgrestore
       for information on using the back up files.

       In  a  default  installation, each VG is backed up into a separate file
       bearing the name of the VG in the directory /etc/lvm/backup.

       To use an alternative back up file, use -f. In this case, when  backing
       up  multiple  VGs,  the	file  name  is	treated as a template, with %s
       replaced by the VG name.

       NB. This DOES NOT back up the data content of LVs.

       It may also be useful to regularly back up the files in /etc/lvm.

USAGE
       vgcfgbackup
	   [ -f|--file String ]
	   [	--foreign ]
	   [	--ignorelockingfailure ]
	   [	--readonly ]
	   [	--reportformat basic|json ]
	   [ COMMON_OPTIONS ]
	   [ VG ... ]

       Common options for lvm:
	   [ -d|--debug ]
	   [ -h|--help ]
	   [ -q|--quiet ]
	   [ -t|--test ]
	   [ -v|--verbose ]
	   [ -y|--yes ]
	   [	--commandprofile String ]
	   [	--config String ]
	   [	--driverloaded y|n ]
	   [	--longhelp ]
	   [	--profile String ]
	   [	--version ]

OPTIONS
       --commandprofile String
	      The command profile to use for command configuration.  See
	      lvm.conf(5) for more information about profiles.

       --config String
	      Config settings for the command. These override lvm.conf set‐
	      tings.  The String arg uses the same format as lvm.conf, or may
	      use section/field syntax.	 See lvm.conf(5) for more information
	      about config.

       -d|--debug ...
	      Set debug level. Repeat from 1 to 6 times to increase the detail
	      of messages sent to the log file and/or syslog (if configured).

       --driverloaded y|n
	      If set to no, the command will not attempt to use device-mapper.
	      For testing and debugging.

       -f|--file String
	      Write the backup to the named file.  When backing up more than
	      one VG, the file name is treated as a template, and %s is
	      replaced by the VG name.

       --foreign
	      Report/display foreign VGs that would otherwise be skipped.  See
	      lvmsystemid(7) for more information about foreign VGs.

       -h|--help
	      Display help text.

       --ignorelockingfailure
	      Allows a command to continue with read-only metadata operations
	      after locking failures.

       --longhelp
	      Display long help text.

       --profile String
	      An alias for --commandprofile or --metadataprofile, depending on
	      the command.

       -q|--quiet ...
	      Suppress output and log messages. Overrides --debug and --ver‐
	      bose.  Repeat once to also suppress any prompts with answer
	      'no'.

       --readonly
	      Run the command in a special read-only mode which will read on-
	      disk metadata without needing to take any locks. This can be
	      used to peek inside metadata used by a virtual machine image
	      while the virtual machine is running.  It can also be used to
	      peek inside the metadata of clustered VGs when clustered locking
	      is not configured or running. No attempt will be made to commu‐
	      nicate with the device-mapper kernel driver, so this option is
	      unable to report whether or not LVs are actually in use.

       --reportformat basic|json
	      Overrides current output format for reports which is defined
	      globally by the report/output_format setting in lvm.conf.	 basic
	      is the original format with columns and rows.  If there is more
	      than one report per command, each report is prefixed with the
	      report name for identification. json produces report output in
	      JSON format. See lvmreport(7) for more information.

       -t|--test
	      Run in test mode. Commands will not update metadata.  This is
	      implemented by disabling all metadata writing but nevertheless
	      returning success to the calling function. This may lead to
	      unusual error messages in multi-stage operations if a tool
	      relies on reading back metadata it believes has changed but
	      hasn't.

       -v|--verbose ...
	      Set verbose level. Repeat from 1 to 4 times to increase the
	      detail of messages sent to stdout and stderr.

       --version
	      Display version information.

       -y|--yes
	      Do not prompt for confirmation interactively but always assume
	      the answer yes. Use with extreme caution.	 (For automatic no,
	      see -qq.)

VARIABLES
       VG
	      Volume Group name.  See lvm(8) for valid names.

       String
	      See the option description for information about the string con‐
	      tent.

       Size[UNIT]
	      Size is an input number that accepts an  optional	 unit.	 Input
	      units are always treated as base two values, regardless of capi‐
	      talization, e.g. 'k' and 'K' both refer to  1024.	  The  default
	      input unit is specified by letter, followed by |UNIT.  UNIT rep‐
	      resents other possible input units:  bBsSkKmMgGtTpPeE.   b|B  is
	      bytes,  s|S  is  sectors	of 512 bytes, k|K is kilobytes, m|M is
	      megabytes, g|G is gigabytes, t|T is terabytes, p|P is petabytes,
	      e|E  is  exabytes.  (This should not be confused with the output
	      control --units, where capital letters mean multiple of 1000.)

ENVIRONMENT VARIABLES
       See lvm(8) for information about environment  variables	used  by  lvm.
       For example, LVM_VG_NAME can generally be substituted for a required VG
       parameter.
