backup rotation
<operating system> Any system for re-using backup media, e.g. magnetic
tape. One extreme would be to use the same media for every backup (e.g. copy
disk A to disk B), the other extreme would be to use new media every time. The
trade-off is between the cost of buying and storing media and the ability to
restore any version of any file. One example is the Grandfather, Father, Son
(GFS) scheme.
