I just built a new server rig, I have a 90GB SSD as sda1 for OS and server files, and I installed a 500GB HDD to use for backups and archives. I cant seem to figure out where to change the backup and archive locations to /mnt/storage/backup and /mnt/storage/archive
Looked in /usr/games/minecraft/mineos.conf and dont see anything related to backups in there…
Where to look?
Thanks
i got it.
Symlinks are your friend
For future readers, what the OP ended up doing was replacing real directories in the /var/games/minecraft tree with symlinks pointing to their respective new locations.
Thus any and all activity operating on /var/games/minecraft/backup could then point to /mnt/storage/backup.
# ln -s /var/games/minecraft/backup /mnt/storage/backup
Pardon the necrobump - but this still seems relevant to new viewers of the topic.
In contrast to the original poster’s method, I prefer to store my backups offsite. I use AWS S3 buckets as they are incredibly cheap ($0.03/GB/month) and reliable (99.99%.) My method is to daily archive my MineOS worlds via MineOS’s schedule functionality, destructively sync with the S3 bucket, then delete old archives.
It is important to schedule your backup before the sync occurs, otherwise it won’t be synced until the next scheduled cycle. It is also important to sync to S3 before automatically deleting old archives. Remember to pad enough time for the previous step to complete before starting the next cronjob. Personally, I give 30 minutes for the scheduled archive (even though it generally occurs in under a minute) and 1h45m for the S3 sync to occur. YMMV.
There’s several areas for improvement in the approach below such as triggering the deletion only after a successful upload, but it’s “good enough” 
Schedule daily backups/archives within MineOS’s schedule:
30 2 * * * archive
Destructively sync with the AWS S3 bucket by defining a cronjob (crontab -e) as the user associated with your MineOS service, which is mc by default . The example below deletes archives older than a week ("+6"). Destructively syncing removes older archives and keeps your local filesystem and S3 bucket from getting too large.
Prerequisite: awscli must be installed. On Debian/Ubuntu use apt-get install awscli
Destructively sync
0 3 * * * /usr/local/bin/aws s3 sync --delete /var/games/minecraft/archive s3://bucketname > /dev/null
Delete old local archives by defining a cronjob (crontab -e) as root. The example below deletes archives older than a week ("+6").
45 4 * * * find /var/games/minecraft/archive/ -type f -mtime +6 -exec rm -rf {} \;
At the moment there is no way (that I’m aware of) to delete previous archives in MineOS (@hexparrot, this functionality would be amazing! I have some free time this summer and would love to implement this as well as the Download functionality I brought up a while ago)
