Operating Systems Linux Red Hat Backup and restore using tar Post 302759053 by hicksd8 on Monday 21st of January 2013 09:56:09 AM

The /dev directory holds the device nodes for the hardware. It is the connection between the O/S and the actual hardware (eg, /dev/sda being a disk drive).

When you restore a backup to different hardware, these devices will be wrong for that hardware and will need to be rebuilt/reset to suit. I'm not a RedHat expert so I don't know exactly how that would be achieved. Perhaps RedHat experts on this forum can tell us how to restore to different hardware.

Anyway, the point is you need to backup all hard disk directories and ignore the directories which are really pseudo memory (eg, /proc). You need to distinguish between the two.

Work on the principle that it is better to have a backup containing stuff that is unnecessary and/or needs modification to suit new hardware rather than not have a copy of it at all.

Cannot restore a TAR backup

I backed up a unix database using "tar -cvf /dev/rmt1 -N 800 /*" Normally I would restore this using "tar -xvf /dev/rmt1 -N 800" This is reporting an error about "not enough memory" I have done a new test backup and restore using the same commands and they work. ANY IDEAS ? (2 Replies)

NAME

       vxconfigbackup - back up disk group configuration

SYNOPSIS

       /etc/vx/bin/vxconfigbackup [-l directory] [[dgname ...] | [dgid ...]]

DESCRIPTION

       The  vxconfigbackup  utility  can  be  used to backup up the configuration information for one or more disk groups.  The disk groups may be
       specified either by name or by ID.  If no disk groups are specified, all disk group configurations are backed up.

OPTIONS

       -l directory
		 Specifies a directory other than the default where the backup configuration files are to be written.

		 Note: The default backup directory is /etc/vx/cbr/bk.

EXAMPLES

       Back up the configuration of the mydg disk group to the directory /dgbackup/mydg:

		 vxconfigbackup -l /dgbackup/mydg mydg

FILES

       /etc/vx/cbr/bk/dgname.dgid/dgid.dginfo
		 Default location of backup file for disk group information.

       /etc/vx/cbr/bk/dgname.dgid/dgid.diskinfo
		 Default location of backup file for disk attributes.

       /etc/vx/cbr/bk/dgname.dgid/dgid.binconfig
		 Default location of backup file for binary configuration copy.

       /etc/vx/cbr/bk/dgname.dgid/dgid.cfgrec
		 Default location of backup file for configuration records in vxprint -m format.

NOTES

       The vxconfigbackupd daemon automatically backs up a disk group's new configuration to the default backup directory whenever the	configura-
       tion is changed.  The vxconfigbackup command is provided to back up the configuration manually at any other desired time.

       The  disk  group  configuration	backup and restore utilities do not save any data in the public region. This includes file system or other
       application data that is configured within VxVM objects.
