In a personal computing arrangement and utilizing full and Incremental method, shold we use two separate external storage devices to do this or could this be done on one larger storage media? I realized We could end up with 4 separate medias.
When planning the backup implementation remember how long the backup takes, storage accrual, and location.
Another thing is incremental = backup duration has constraints
Differential is the medium of the road approach, but more storage accrual
External backups can be on the same external drive, however if the that single drive fails you will lose all data.
