An unofficial simple shell script to push a local Proxmox Backup Server datastore to a remote rsync location.
I wrote this script to automate offsite backups from a Proxmox Backup Server. The current version of PBS 3.0 has the option to sync to a "remote" which is another PBS at an off-site location. I simply want to sync the datastore to an offsite server that cannot have PBS installed.
This JSON file has all the information you will need to provide so the script can send the data to the correct place. For multiple datastores, create a new config file for each and use it as the script parameter.
remotehost : The remote server you would like to send data to.
remoteuser : The SSH user on the remote server.
remotepath : The filesystem path on the remote server that you would like to store the backups in.
logpath : The path on your local server that you would like to store the script's logs in. Do not include a trailing slash.
datastore : The case sensitive name of the PBS datastore you are backing up.
emailrecipient : The email address that the script should send success or failure emails to. This uses the mail command and assumes that you have email configured in PBS.
You will need SSH keys set up between the client and server.
Make script executable
chmod u+x backup.sh
Fill in config file details
Run script
./backup.sh config.json
For automated backups, you can add it to your crontab.
To restore, you can either use rsync manually or use the included interactive restore.sh script.
restore.sh uses the same config.json file that backup.sh uses. It will reverse the rsync command and pull the data back into the datastore that is specified in the config file. Please make sure you do not have anything you want to keep in the local datastore before running this. This will overwrite eventhing inside.
Run script
./restore.sh config.json
