On my backend my boot device and "/" directory is a 16GB Flash drive. I
did something stupid and filled up the drive.  So after deleting the
file I moved to the wrong place I'm back to the normal free space.

But it brings up a question.  Does mythbackend use temporary disk space
somewhere on "/" that I need to redirect to one of my 2TB hard drives?
I have tons of free disk space just not on "/"

My first guess is all the /var/lib/mythtv/* files to see which grow
large over time.  Obviously, Default and LiveTV are on the separate hard
drives.

If you have a cron job doing automatic database backups, you need
plenty of space to do that as it creates an ASCII .sql version of the
entire mythconverg database, and then compresses that using gzip.  I
believe it stores the .sql file in /tmp.


Question on the cron job for db backup.  Is this setup on install of mythtv?  I have not created a cron job to do this. But there are a few backups in /var/lib/mythtv/db_backups and I have not run the backup manually yet. I just now ran:
    /usr/share/mythtv/mythconverg_backup.pl
It puts the backup in the directory that I specified in Storage Directories in setup.  I just don't know if it's running automatically.
