# Isonoe Backup Database Server
There is a backup MariaDb database server running on Isonoe.
The database is located on a USB drive on Isonoe at /mnt/mariadb
There is a dump.sh script on Adrastea /home/pi/Boneyard/Import that can be used to dump the database
There is also a send.sh script on Adrastea under /home/pi/Boneyard that can send the compressed backupdb.tar-gz file over to Isonoe
There is a receive.sh script on Isonoe under /mnt/mariadb that will receive the backupdb.tar.gz file from Adrastea.
1) First run the dump.sh script on Adrastea (/home/pi/Boneyard/Import/dump.sh)
2) Next run the receive.sh script on Isonoe (/mnt/mariadb/receive.sh)
3) Next run the send.sh script on Adrastea (/home/pi/Boneyard/Import/send.sh)
4) Finally, run the restoredbzip.sh script on Isonoe (/mnt/mariadb/restoredbzip.sh)
Notes: There is a c++ program that performs the file transfer between Isonoe and Adrastea.
The program is maintained on the Gitea repo under CPP/sstp
The build project for this is maintained on Isonoe under /home/pi/CPP/sstp with libraries located under /home/pi/CPP/common
