remote office backup software.

hi all,

ive 8 workstations working with me and ive no idea how to make them all do backup everyday since the data are kinda impt.

what if the next day their hard disk crushed and all data went missing?

some have no knowledge on schedule backup. and some work till late night and do not be able to backup on their own in the end.

i came across the net that there is a remote office backup software.

or shld i jus install another extra hard disk into the machine?

anyone had any recommendations or suggestions to share with me?

thanks so much.
