Manual backup

As CRCON is running in Docker containers, you don't have to backup anything else but its own folder on your VPS.

Caution

You CAN'T backup a running CRCON.
The CRCON's folder contains the database files, which are accessed multiple times per minute, even if there's no player on your game server.
Making a copy of a running CRCON's folder WILL lead to data loss. You could even get a corrupted database.

Note

We'll assume you have installed CRCON in its default /root/hll_rcon_tool folder, following the installation guide.
Adapt the commands given below if necessary.

Enter an SSH session on your VPS

See Installation step #1

Stop the CRCON Docker containers

cd /root/hll_rcon_tool
docker compose down

Create a backup of the CRCON's folder

cp -r /root/hll_rcon_tool "/root/hll_rcon_tool_backup_$(date '+%Y-%m-%d')"

Note : this may take some time, especially on CRCON(s) that have been managing one or several crowded game servers for a while, as their database(s) contain(s) all the logs the game server(s) have sent.

You now have a full copy of your CRCON installation on your VPS, in the /root/hll_rcon_tool_backup_XXXX-XX-XX folder.

Restart the CRCON Docker containers

docker compose up -d --remove-orphans

Managing the backup files

Compress the backup folder

CRCON's files aren't very large, but its database could grow to several GBs as it has been running for weeks/monthes/years.
So you may want to compress the backup folder, either to minimize the storage space it occupies, or to send a copy of it to another server or your personal computer.

-> Follow the Migrating steps.

Warning

Remember to replace the compressed folder's name in the commands (hll_rcon_tool -> hll_rcon_tool_backup_XXXX-XX-XX).

Revert to the backup version

If you want to revert your CRCON back to the state it was on backup time, you'll have to enter these commands :

cd /root/hll_rcon_tool
docker compose down
cd /
mv /root/hll_rcon_tool /root/hll_rcon_tool_bad
cp -r /root/hll_rcon_tool/backup_XXXX-XX-XX /root/hll_rcon_tool
cd /root/hll_rcon_tool
docker compose up -d

You'll then have three CRCON folders :

• the running version : /root/hll_rcon_tool ;
• the initial backup, similar to the running version : /root/hll_rcon_tool/backup_XXXX-XX-XX ;
• the reverted ("bad") version : /root/hll_rcon_tool_bad.

Delete a backup

Delete the backup

Tip

We advise to keep it, as you want to have it handy in case of major failure of the running version.

rm -r /root/hll_rcon_tool_backup_XXXX-XX-XX

Delete the "bad" version

rm -r /root/hll_rcon_tool_backup_bad
