Sometimes, when backing up very important information, it may be required to synchronize a single source directory with two destination directories, potentially located on different physical disks, servers or NAS storage devices. Making a third copy of important files significantly reduces the risk of losing the important information in the case that one of the backup copies will be destroyed by a catastrophic hardware failure.

SyncBreeze Pro and SyncBreeze Server allow one to define a tertiary destination directory for any file synchronization command. In order to configure a tertiary destination directory, open the file sync command dialog, select the 'General' tab, select the 'Extended' configuration mode and specify a tertiary destination directory. During runtime, SyncBreeze will first synchronize the source directory with the first destination directory and after that with the tertiary destination directory.
