External Backup Script using Rclone
This script is unofficial and not supported by Ultra.cc staff.
This Shell script will allow for an automatic backup of important information related to the configuration of your applications excluding Plex.. It can then be configured to store it or either Google drive or a local folder on your Ultras Slot.
Initial Setup and Configuration
create three new folders, one may already exist this is fine
mkdir ~/lock
mkdir ~/scripts
mkdir ~/autobackup
Then you need to enter the new folder called scripts
cd ~/scripts
And create the script file
nano backup.sh
Paste the following lines into it :
#!/bin/bash
exec {lock_fd}>/home/your-username/lock/BackupLock || exit 1
flock -n "$lock_fd" || { echo "ERROR: flock() failed." >&2; exit 1; }
if [ -z "$STY" ]; then exec screen -dm -S autobackup /bin/bash "$0"; fi
DATE=$(date +%Y-%m-%d-%H%M%S)
tar --exclude="$HOME"/.config/plex -czvf "$HOME"/autobackup/MyUSBbackup-$DATE.tar.gz "$HOME"/.apps "$HOME"/.config
rclone copy -v --bwlimit=5M /home/your-username/autobackup/ remotename:/”My USB Backup”
flock -u "$lock_fd"
Save it by pressing Ctrl+X then Y then Enter
.
You will need to change the paths home/your-username
to match your own home and username. You will also be required to change remotename to match your rclone remote name which can be found with the rclone config command or rclone listremotes. These need to be run via SSH Command line.
Testing
So to test first we navigate to ~/scripts folder we made earlier
cd ~/scripts
Then we need to allow the backup.sh permissions to run
chmod +x backup.sh
And finally, run it
./backup.sh
If all went well * tar -ztvf ~/autobackup/.tar.gz should show a bunch of files starting with /home/username/.config and /home/username/.apps inside.
If the script is running and you were to rerun it, you may see an error message
“Flock Failed” this is a file lock to stop multiple downloads running and is
normal. If you are sure it isn’t running you can delete the lock file from
~/lock. You can also check the progress of the backup script, which is running
in a screen with the command screen -rd autobackup
and then to exit the screen while keeping the command running use the keyboard combo CONTROL + A + D
If all is well after the test, we can automate the check via crontab
Open crontab with
crontab -e
You may have a choice of editors. We recommend Nano
Inside the crontab add a single line under everything else in the file that looks like this
0 0 */3 * * /home/your-username/scripts/backup.sh
Save it by pressing Ctrl+X then Y then Enter.
The script will now run every 3 days, checking for files that have changed and syncing them to the destination folder
