With the new Dell computer, I chose to use CWRSYNC to backup daily all my data to a RAID 1 array of two external hard drives. CWRSYNC is the reincarnation of outstanding program rsync on linux/unix for syncing up file systems.
It works like a charm on Windows 7.
Here’s the command I’m using. no-p avoids the “failed to set permission” error.
rsync -av --no-p --delete /cygdrive/c/work/ /cygdrive/x/work/
