BackUp

We have a simple routine for backup copying. It is quick, efficient, inexpensive and safe.

At about 12:00 noon (lunchtime) and again about 16:00 (end of workday), we take an incremental backup (meaning a backup of all files that have been changed since the previous total backup).

Once a week (typically on Friday afternoon), we take a total backup.

Once a month we save the total backup in the safe-deposit box.

We copy these files onto a DVD disk (you can use a CD disk if you have a minor amount of data to be stored). You get 2-3 DVD disks for one dollar, and we have space for 3-5 backups per disk (1 for a total backup). This means that each backup costs us one fifth of a dollar and takes us two-three minutes (we start the backup process when we leave for lunch and it is completed when we return to work).

A good and free program for the backup process is Cobian BackUp

As a standard, the program is always available in the system status field; if one only wants to start it manually, the command cobian–m can be used.

You might say that the Cobian program works in the same way that Windows' own built-in backup program should work.
