incremental and differential backups

view full story

http://www.linuxquestions.org – Hi All, Can differential backups be used to solve missing incremental backups? Say you take daily incremental backups, then for one reason or another you lose the incremental backups for the next 3 days. Can you perform a differential backup to cover to gap somehow? As a point of reference for the differential backup, i think i can use the log for the incremental backup, or generate an empty dummy file daily(to be batch deleted on the next full backup). For example: July 26 : full backup July 27 : incremental backup; (HowTos)
