I got my answer to this on the Live Chat, but wanted to make sure everyone has access to it:

What is the best method of backing up Fop2? I am using FreePBX 6.12 64bit distro (FreePBX 5.211.65, Asterisk 11 with CentOS 6.5). I notice I can use the FreePBX GUI / Admin / Backup & Restore to administer backups of any folder on the system, but will it work to just backup the [code]/usr/local/fop2/[/code] folder?

fop2 settings are stored in tables in the asterisk database. That database is usually backed up by any backup module you might have already, then the actual files are [code]/usr/local/fop2[/code] and [code]/var/www/html/fop2[/code]. If you can add folders to your backup, you can add those, sure. Then the service script is another thing, as you have some files but also you must enable them as a service if you are restoring.

Then in disaster recovery I can do a fresh install of CentOS/FreePBX distro and just restore all of that, and it should work?

It is not enough just by copying files. The files are [code]/etc/rc.d/init.d/fop2[/code] and [code]/etc/sysconfig/fop2[/code]. [code]chkconfig[/code] is the command to control the service. Add [code]/etc/rc.d/init.d/fop2[/code] and [code]/etc/sysconfig/fop2[/code]
but then you will have to use [code]chkconfig --add fop2[/code] to add the service in case you restore the files that way
or just download fop2, extract and run [code]make[/code] to install over, the make install will run [code]chkconfig[/code] for you
either way will work.

Final note... the license will probably fail on a new installation, so you will have to revoke/register
