Can I backup files to a CIFS or smbfs mount?
You can certainly try! Using a CIFS or smbfs mount as the mirror directory has been troublesome for some users because of the wide variety of Samba configurations. If possible, the best solution is always to use rdiff-backup over SSH in the default configuration. Under both Linux and Mac OS X, smbfs seems to be working quite well. However, it has a 2 GB file limit and is deprecated on Linux.

Using rdiff-backup in the default configuration is also guaranteed to be faster because there is lower network utilization. Rdiff-backup uses the rsync algorithm to minimize the amount of bandwidth consumed. By using smbfs or CIFS, the complete file is transferred over the network.
