HyperSync in Incremental Backup
You may enable the HyperSync in Incremental Backup setting at the
checkbox in the Advanced Settings tab in the main window.
Alternatively, you may enable the option with the following command
line argument:
-
One of XXCLONE-Pro's popular usages is the periodic backup
operation. In the Incremental Volume Backup and the
Windows Key Directory Backup modes, XXCLONE speeds up the
clone operation by skipping files that are determined to be
the same since the previous backup operation.
When the HyperSync Algorithm is enabled, XXCLONE goes one step
further and tries to identify directories whose contents have
not been changed since the previous backup operation.
When a directory is determined to be unchanged, the examination
of the whole contents (member files) in the directory will be
skipped to save time. Directories that contain
a subdirectory will not be skipped.
The effectiveness of this scheme is most profound when
the amount of disk activities (i.g., the computer usage)
since the previous clone operation has been relatively small.
-
One notable use of this feature is to run a volume backup
operation in the incremental mode (
/backup2)
twice.
In the first backup operation, you may use the computer in
the normal fashion while XXCLONE operates in the background.
(Say, you browse the Internet, send Emails, edit a document, etc.)
By not terminating all active programs while XXCLONE is running
in the background, some files that are being accessed during this
period may not be properly backed up. After the first round
of XXCLONE operation completes, then, terminate all running programs
and run XXCLONE once again for a more complete volume backup.
The second run of the volume cloning operation will save the files
that failed to be backed up in the first run. In such a case,
the HyperSync algorithm makes an appreciable difference in the time
to complete the job.
