Top Forums UNIX for Advanced & Expert Users Why is editing a file by renaming the new one safer? Post 303042578 by joeyg on Monday 30th of December 2019 09:43:33 AM

Seems illogical to me.

When working on complex programming, I often take the backup even more seriously. I sequentially number versions to help me go back and find prior logic.
cp GreatScript GreatScript.v001
then continue editing GreatScript, until I get to another good spot and
cp GreatScript GreatScript.v002
and continue with this process.
Eventually, I often create an Archive folder, and then mv GreatScript.v* ../Archive

Sometimes, it is only apparent much later on that there was a major mistake in coding - and a need to go back further than only one version. Plus, while developing, I always feel better knowing more than one backup copy.

NAME
vxconfigbackupd - disk group configuration backup daemon SYNOPSIS
vxconfigbackupd [-l] DESCRIPTION
The vxconfigbackupd daemon automatically backs up information about a disk group's new configuration whenever the configuration is changed. OPTIONS
-l Logs backup daemon activities to the file /etc/vx/cbr/bkdaemonLog. FILES
/sbin/init.d/vxvm-recover Startup file for vxconfigbackupd. /etc/vx/cbr/bk/dgname.dgid/dgid.dginfo Location of backup file for disk group information. /etc/vx/cbr/bk/dgname.dgid/dgid.diskinfo Location of backup file for disk attributes. /etc/vx/cbr/bk/dgname.dgid/dgid.binconfig Location of backup file for binary configuration copy. /etc/vx/cbr/bk/dgname.dgid/dgid.cfgrec Location of backup file for configuration records in vxprint -m format. NOTES
The vxconfigbackup command can be used to back up a disk group's configuration manually at any 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. When a disk group is destroyed, its configuration backup information (including the backup directory) is also removed. The only exception to this behavior is when the disk group is in the precommit state of restoration. The backup directory should be large enough to accommodate copies of all the currently imported disk groups. The minimum recommended size of the backup directory is P * (N + 1) megabytes, where P is the private region in megabytes (by default, 32MB), and N is the number of disk groups. The additional P megabytes is required to hold a temporary copy of the disk group configuration when a disk group is imported or a configuration change is made. The default backup directory is /etc/vx/cbr/bk. The location of the backup directory can be configured by using the vxconfigbackup -l backup_directory_path command. SEE ALSO
