Whenever we get into a discussion around recovery SLAs, it
always starts with the customer saying the same thing. Terms like
"immediately", "ASAP", and "yesterday" come up, to which we start
the discussion of what's truly attainable.
What's attainable really revolves around what you want to invest
in keeping a system running in the first place; if you truly can't
afford a system to go down, perhaps looking into redundant systems
or virtualization should be on the table first. But, assuming you
are more interested in just having as fast a recovery as possible
instead, there are two factors to consider:
What's being recovered - we need to define what
needs to be recovered - data, servers, workstations, full OS
recovery, etc. - in order to design a recovery service that can
meet the need. If simply data, an SLA is determined by the speed of
the backup solution (which we'll get to in more depth in a moment).
If complete servers down to the bare metal (meaning we'll need to
recover to a brand new piece of hardware) need to be recovered,
it's an entirely different timeframe. If workstations come into
play (which they should - your employees can't work without
workstations!), the number of workstations and whether you want
just a simple image to be used to recover, or backups of each
individual workstation all come into play.
What solution is used - This is almost more
important, because you can desire to have everything recovered and
yet, the tapebased backup system in your business (as the case may
be) only has the capacity to backup the data on your server.
This is one of the reasons we prefer to use hybrid cloud backup
as our medium of choice. If you're not familiar with it, backup is
accomplished by backing up to a secure data center across the
Internet ("in the cloud") and that data is replicated to network
attached storage (NAS) placed on-premise in your business. The
local NAS provides robust speed of backups and recovery, while the
cloud provides automatic redundancy for your backup data with an
ability to recover - even if you need to recover to an alternate
So obtaining the answer for an appropriate recovery SLA isn't a
simple exercise. It's going to require understanding what your
business needs are and a willingness to possibly move to a more
scalable, robust backup & recovery solution.
