Remote Data Management & Backup with Snap EDR
In the first, more common, approach to consolidated
backup, data at remote sites is periodically analyzed to
determine differential data (i.e. data that has changed)
since the last backup process. A copy of this differential
data is then moved to a central site, where it is stored
on disk. Some technologies have the ability to discern
just the byte-level modifications of files to minimize
the amount of data needing to be transferred. Data
can be stored as incremental packets of data or re-
constructed on the central site to provide full, up-
to-date copies of remote files. This latter alternative
provides the advantage of offering instant access to
individual files in the case that a remote file is
accidentally deleted.
In the second approach, backups are run on remote
servers with the output stored to the local disk. The
resulting backup image is then transferred to disk at
the remote site. This works well for applications that
have native backup or snapshot features that can be
utilized in the consolidated backup process.
These approaches can also be used together. For
example, backing up user files may be best performed
with differential data transfer, while backing up
Exchange data may be best performed using the
consolidated backup image approach.
In both approaches, the backup data on disk at the
core location can be further sent to tape if desired.
Companies often choose to keep one or two days of
backup data on disk for
instantaneous access, with older
data written to tape.
Consolidated Archive
Consolidated archive involves
identifying remote data that meets
corporate archival policy and then
moving that data from remote
systems and archiving it to a central
disk. Archival policy determines
what data should be archived and
when, and parameters often include:
last date accessed, type of file,
content, location, ownership, size of
file, among others. A consolidated
archival process has many benefits
such as:
• Reducing the amount of data to be backed up
(reducing the backup window required)
• Optimizing use of remote disk for better
performance and cost
• Ensuring compliance to data retention policies and

regulations
An essential part of consolidated archive is some
mechanism by which data can be retrieved from the
archive by end users, preferably without the
involvement of IT.
Central policy-based consolidated processes, such as
consolidated backup and archive, provide an approach
to managing data at remote offices that can significantly
lower costs, eliminate risk, improve data consistency,
and also ensure better compliance to corporate backup
and retention policies. It is an approach that all
businesses with remote offices should actively consider.
