Backup - Toshiba PX1267E-1G32 User Manual

Backup

The Backup operation is best suited for those who want to backup
their entire startup disk. As well as backing up files, Backup can also
save other types of data, including user settings, applications and
their settings, and the operating system and its settings (including
the registry). This information is required if you need to perform
disaster recovery on a computer that has become unresponsive.
Backup Stores, Catalog Files, and Snapshots
The Backup process "packages" backed up files, saving them in
a proprietary format, and storing them in a Backup Store, complete
with encryption, and compression, if specified. Files in a Backup
Store cannot be accessed via the Desktop; they can only be
accessed through the Regen interface.
Regen keeps track of files in a Backup Store using a special type of
index called a Catalog File. At each backup session, Regen takes
a Snapshot of the source volume. The Snapshot is a record of all
the files on the source at the time of the backup. While only the
most recent Snapshot is saved in the Catalog file, Regen saves every
Snapshot ever taken to the destination (i.e. your Toshiba Drive). In
this way Regen can keep track of all versions of backed-up files in
a very organized and efficient manner. Because all previous versions
of backed up files are saved in the Backup Store, you have the
ability to restore a file from any point in the backup history.
