Problems with File
Restoration
The second, and perhaps more significant drawback,
is the time needed to restore from partial file
transfer systems. The recovery process does
not just involve the recovery of the file itself.
Instead the restoration process starts by retrieving
the original file then continues by retrieving
and confirming every change made to that file
for the life of the backup. The longer the backup
account has been active, the longer the recovery
time required. Magnified over the full data
store this will impact the recovery time considerably.
DataFort’s Common
Sense Alternative
At
DataFort we opt for the simple and more
pragmatic file versioning approach to
backup. In this method the entire file
is sent whenever the file changes. This
increases the time needed for the backup
process. Data restores, on the other hand,
are much more efficient. The latest version
of the file is restored, and that’s
it. So no matter how long you have been
running your backup the only restore required
is the latest backup version of the file.
The backup cost can also be managed much
more effectively, just keeping the number
of file versions you require, not a lifetime
history of the changes.
