They can be used for restore operations as indicated in the quote I posted about "for restore operations", but this logging slows down MySQL and I wouldn't ever enable it just for 1 account in a shared situation. There are other backup methods that will not slow down MySQL for everyone such as simply getting cPanel backups. Restoring from the bin logs is not as straight forward as restoring from the cPanel MySQL backups either.

You can certainly enable it, but I wanted to point out earlier it's really only ideal for replication purposes. It isn't the preferred method to create simple backups, although it is possible to use for restores. Basically, when you enable it, you are enabling it for the entire server for all databases. If it is only being added for 1 user's databases, the offset in slowdown isn't beneficial to warrant it. There are faster backup methods that are easier to perform for individual databases.
