Abstract
A method, system computer program product recorded on a computer readable medium, for fast incremental backup of a storage device includes selecting an area of the data storage device for backup; creating the bitmap of data storage device; reading the selected area of the data storage device; converting data read from the data storage device into a usable format for the comparison of descriptors; reading descriptors of logical storage units of the selected area; discarding selected data access attributes of the descriptors; generating hash values for the descriptors; comparing the hash values of the descriptors of the logical storage units of the selected area with the hash values of the descriptors of previously archived logical storage units; for physical storage units related to logical storage units of the selected area whose hash values of the descriptors are identical to the hash values of the descriptors of the archived logical storage units, checking if these physical storage units need to be backed up; updating the bitmap of data storage device; and backing up contents of the physical storage units marked in the backup. The logical storage units can be files. The descriptors can be compared on a physical storage unit basis.
