Display backup file information - showbackup.sh
« on: August 08, 2010, 05:01:51 PM »
Below is a script that will display a listing of the files in your backup in descending order based on file size.   For each file in your backup, it will show the size and what the percentage of space that the file takes verses the entire backup file size (I found on my system that there is one file in my backup that takes up 86% of the backup)    At the end of the output, there is a summary that shows your backup file size both compressed and uncompressed.

Hi ixbrian
I wanted to include a link to this script as part of an answer in another thread. I found it doesn't work with
TC4.1 because  backup_device  was moved  from /opt to /etc/sysconfig. I hope you don't mind, I made two
small changes to make it compatible for both cases. Signed comments included to show what I did.

Patches will be deleted after 90 days.

Be assured though that the diff referenced by the now dead link was of exact same content as what is still available inline, just in the more practical form of a downloadable file.
