I'm looking for a simple way to schedule full + incremental backup of a remote FTP server (that also supports SFTP, but without SSH access) from My NAS that is based on Linux, WITH full SSH access. I'm surprised by the fact that there are a lot of solutions, but many of them are quite "oversized" for a simple task like this (for example: Bacula).
The idea is to setup a full backup every week and the rest will be daily and incremental.
Thank you for your help.
