What's the difference between .backup and .rsc file?

Hi everyone, there seems 2 different method to backup/restore RouterOS configuration: use “file” to generate a .backup file, or “/export file=12345.rsc” in console to generate a .rsc file. I found .backup file is bigger and contains more information, for example, it will become bigger even if I just reconnect Wan… What’s the difference between them? What do backup contains while rsc not contain? Thanks.

rsc a script and is human readable with plain text reader soft.
Backup is a internal routeros backup and probabily there is user info and some graphs log history that is not present in .rsc file.
I’m using always the two options. Backup for fast restoring and rsc for reviewing config before restore or if there are problems restorig a backup in a newer ROS versión. My experience says is always good to having multiple restoring options because restoring backup files not always has worked well for me in the past.

.backup file is binary one used to recover configuration bit by bit…remeber that backup done for one ROS version could not be proper to be restored when you change ROS version.

.rsc file is just text script of all CLI commands needed to be issued to make your configuration same as it was during .rsc genaration.

Thank you everyone, I just read my rsc file and find it doesn’t content any user password, but it do show WIFI and PPP passwords, what else I need to configure manually if I recovered by rsc file from default resetting?
