It is important to backup regularly not only your personal data, but also your entire system, installed programs and configurations. Many backup programs use simple VSS (Volume Snapshot Service) mode to create a snapshot. Stratesave uses VSS advanced mode, which works in cooperation with the installed programs (writers). VSS writers are selectable with Stratesave. Windows System, SQL Server and other installed programs contribute to the snapshot for most precise snapshot generation and later backup. Stratesave also backs up NTFS specialities, Links, Security, Streams, Reparse points etc. Together this enables you fully restore your system in case of a disk crash or other failure.

The Stratesave differential backup feature for System State keeps the daily or weekly backups small, and still System can be recovered to most recent state when disaster strikes. Differential backups can also be stacked. For example, make a full backup every year, differential backup which base on the full backup every month, and daily or weekly differential backup which base on the latest monthly backup and are kept small.
