It is easy and efficient when creating

backup chains.

Demerits

Resulted backup images may contain a

lot of redundant data.

It depends on a file system structure, so

you won’t be able to process unknown

file systems.

It is ineffective when trying to maintain a

backup chain, especially when little

amount of data is being changed.

It cannot be used to back up a system

partition.

It is much slower when processing large

amount of data.

Backup Types

At the present moment the market is offering various types of backup imaging to meet the needs of

any user. Besides supporting them all, our program offers a unique backup type, called File

Increment to a Sector Backup.

Full and Differential Sector Backups

A full sector-based backup image includes all contents of a partition or a hard disk at the moment of

its creation. If you roll back your system to the initial state on a regular basis, that’s exactly what

you’re looking for. But if you want to have multiple backup archives of the same partition reflecting

certain time stamps, unchanged data will inevitable be duplicated in all archives and take

additional space on backup media. To tackle this issue there has been developed a supplementary

technique called Differential Sector Backup.

A differential archive only contains data changed since the time of creating a full archive, which

forms a base (or a parental image) in this case, thus considerably saving your system resources. It is

realized by the exact bit-wise comparison of the previous partition's data (saved in the parental

image) with the current data (that is actually the partition itself). To restore this kind of backup you

will require a full image and one of its differentials, what is very convenient.
