FreeFileSync does not support accessing FTP volumes directly. But this functionality can be integrated by mapping the FTP web space to a drive letter:
Example: Use the free utility NetDrive (http://www.netdrive.net)
Add a New Site and specify site name, site URL, drive letter, account and password.
Use the newly created drive as if it were a normal hard disk.
Note
Most FTP drives set a
file's time stamp to the current time when synchronizing ignoring
the source file's time and date. As a workaround you can do a
Compare by File Size.
An SFTP share can be easily mapped onto a local folder for use with FreeFileSync:
Install: Mount
SFTP share: Unmount:
sudo
apt-get install sshfs
sshfs
ssh-account@ssh-server:<path> mountpoint
fusermount
-u mountpoint
