Backup Script for Vodia PBX

[Quinntin Comer]

Hi folks,

 

Thought I would share this in case anyone was interested. This is just a daily script for backing up the PBX data directory.

We have a file "vodiapbx-backup" in the /etc/cron.daily folder with no extension, just named "vodiapbx-backup", so that it will run dailly.

You can see when your cron jobs are scheduled by running the following command: 

grep run-parts /etc/crontab

and you will see results similar to:

17 *    * * *   root    cd / && run-parts --report /etc/cron.hourly
25 6    * * *   root    test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.daily )
47 6    * * 7   root    test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.weekly )
52 6    1 * *   root    test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.monthly )

Based on the results above, you can see our daily will run at 6:25 daily.

In that "vodiapbx-backup" file, we have the following script:

#!/bin/sh

# Set the variables
source_dir="/usr/local/pbx"
backup_dir="/data/backups"
now=$(date +%Y%m%d)
filename="VodiaPBX_Backup_$now.tgz"

# Delete backups older than 7 days
echo "Deleting older backups"
find "$backup_dir/*.tgz" -mtime +7 exec rm {} \;

# Start Backups
echo "Starting Backup"
tar -zvcf "$backup_dir/$filename" "$source_dir"

 

This script will perform the following:

• Define the following variables:
  • source_dir: This is the source directory we want to backup
  • backup_dir: This is the path where we want to store our backup (in our case, we have a mounted volume)
  • now: This is the current datetime stamp with YYYY/MM/DD format.
  • filename: This is the filename to use for the backup file, example: VodiaPBX_Backup_20230912.tgz"
• Deletes any tgz files older than 7 days from the backup_dir path
• compresses the source_dir path into $backup_dir/$filename

Noice. thanks for sharing! 

I use this to replicate every hour to another datacentre for a worst-case scenario. It only does the changes with a bandwidth limit. 

@hourly rsync --bwlimit=2048 --delete-before -av /usr/local/pbx ******@****.***:/usr/local/

Absolutely could add that as a step!

I had to modify this line to ... (remove "'s and add - to exec)

find $backup_dir/*.tgz -mtime +7 -exec rm {} \;

 

Other than that everything else works perfectly, very helpful, thanks!
