This is not a utility for average users. For experienced Unix systems administrators this is the gold standard.
It might work for you. WAY too hard to set up. Instructions don't match the .conf file. Put a GUI interface on this and you may have a hit. Otherwise, just wasted space on my HD. Buh-bye rsnapshot.
This excellent utility has allowed me to recover accidentally deleted files on numerous occasions. Configuring the cron jobs to allow rsnapshot to run automatically can be tricky, but this is a 'set and forget' type of task.
Really hard to set up... did the install and tried to set this thing up... as it is in the instructions... nothing... just bad!
