I recently came across an article
called "Are application-specific backup tools worth it?" by Simon Sharwood. The article compares enterprise backup vendor approach to point application specific
solutions, using SharePoint as an example. I think, in this article Simon brings up one of the most important issues that we are solving with Quest Recovery Manager for
SharePoint: how to connect cross-application enterprise backup efficiency
with the need for granular SharePoint-specific recovery solution. I could not
find a way to submit a comment to the article at SearchStorage site, so I'll
just post my thoughts here.
Backup and recovery ultimately
share the same goal, but it is important to understand: each task has quite
different requirements. It becomes more visible in large organizations but
seems to apply everywhere. Here's what I mean:
-
Backup is a periodic routine driven by
administrator; typically, it is scheduled and performed off hours; major
concerns are storage requirements and costs, so appropriate processes and
technologies are in place are involved (e.g., tape libraries, tiered storage,
etc.)
-
Restore is a one-off activity, initiated
or driven by the end user; it occurs as-it-happens, more often than not -
during production hours; major concerns are time to recover and accuracy of the
restored data.
Traditional backup vendors that are
offering cross-application backup products primarily focus on the BACKUP
requirements. These backup platforms often have built-in backup and storage
management capabilities, tape libraries support, etc. But when it comes to
application specific granular recovery task, sometimes these products (and
backup operators who own them) are not as efficient as you'd like them to be.
What if a SharePoint site is deleted? Document library? An administrator who
owns such backup tool in a company might be responsible for backing up not only
SharePoint farms, but Active Directory, Exchange Servers, SAP databases, and
much more, as well as managing tape libraries and other storage media. This
person might not have enough focus on SharePoint to even know what you are
talking about. They know how to bring back your server, but a doc lib is often
too low level.
The point vendors typically create
SharePoint specific backup infrastructure with the target application in mind.
Knowing different recovery scenarios exist in SharePoint, they try to address
each with a specific backup type, which allows for various levels of
protection. Depending on what backups you are creating with such tools,
recovery is also available at different levels (item, site, or entire
platform), and quite often you end up creating several different backups of
your data for different recovery scenarios. With such tools in hands of a
SharePoint administrator you are probably better prepared to different recovery
situations, but is it really efficient to maintain separate backup
infrastructures for different applications?
We
here at Quest tried to bridge this gap and offer a solution that provides for
SharePoint focused recovery on top of existing backup infrastructure. After
all, if the backup and restore requirements are so different, why not separate
roles here? Let your backup operators do what they are good at, and with the
right tools that meet the backup requirements most efficiently. SharePoint
operations team does not have to do the duplicate job and repeat what someone
else is already doing. But when it comes to a specific recovery task for
SharePoint data, you as SharePoint administrator can be much more efficient if
you have a tool that allows you to search through these backups, locate the
data you need and restore it. That's exactly what Quest Recovery Manager for
SharePoint enables you to do. Net results? Efficient backups, quick and
efficient recovery due to role separation and integration between the backup
and recovery solutions.
