How to backup the CVS repository
Shell scripts to create backups easily
As always, your own your own if the script mess your files up, I just provide the info you are responsible for what you do with it
Any feedback is highly appreciated, you can contact me at this email adress:
1 Backup of CVS
Below is a script I use to make a backup of the part of the CVS that I use.The CVS server we had at my company was not backed up regularly(!), so this was my paranoia to make sure that my stuff would not get lost.
Note that you must use pax if you need to extract the tars.
The files in the tarfile is stored with absolute paths, so you need to strip the leading / if you want to extract the files
(otherwise it will try to extract the files to /cvs... )
do this to extract the files to a directory cvsbkp/
pax -rv -f thetarfile.tar -s "/\/cvs\/data\//cvsbkp\//g"
