Top Forums UNIX for Dummies Questions & Answers Schedule backup with crontab/tar Post 302851357 by edfair on Sunday 8th of September 2013 09:37:04 AM

as you say, entering the tar command as described creates the backup

then you use cron to call a script (you create it) that runs the command (/usr/bin/backup) or whatever else you want to call it or put it.

the rest of the example was used to 1) remove the previous backup so you are not archiving an archive and 2) not to archive a piece of an archive you are creating.

I understood that you were proposing saving the tarball in the same directory that you were tarring.

VGCFGRESTORE(8) 					      System Manager's Manual						   VGCFGRESTORE(8)

NAME
vgcfgrestore - restore volume group descriptor area SYNOPSIS
vgcfgrestore [-d|--debug] [-f|--file filename] [-l[l]|--list] [-h|--help] [-M|--Metadatatype1|2] [-t|--test] [-v|--verbose] VolumeGroupName DESCRIPTION
vgcfgrestore allows you to restore the metadata of VolumeGroupName from a text backup file produced by vgcfgbackup. You can specify a backup file with --file. If no backup file is specified, the most recent one is used. Use --list for a list of the available backup and archive files of VolumeGroupName. OPTIONS
-l | --list -- List files pertaining to VolumeGroupName List metadata backup and archive files pertaining to VolumeGroupName. May be used with the -f option. Does not restore Vol- umeGroupName. -f | --file filename -- Name of LVM metadata backup file Specifies a metadata backup or archive file to be used for restoring VolumeGroupName. Often this file has been created with vgcfg- backup. See lvm for common options. REPLACING PHYSICAL VOLUMES
vgdisplay --partial --verbose will show you the UUIDs and sizes of any PVs that are no longer present. If a PV in the VG is lost and you wish to substitute another of the same size, use pvcreate --restorefile filename --uuid uuid (plus additional arguments as appropriate) to initialise it with the same UUID as the missing PV. Repeat for all other missing PVs in the VG. Then use vgcfgrestore --file filename to restore the volume group's metadata. SEE ALSO
