Given that you are reading this section we will assume
that you actually have a data lost, missing, lock or
corruption issue.
Please remember that panic is your worse enemy in a
data recovery situation. Inform all interested parties
that you have an I.T. issue at present and you will
update them when you have investigated it.
If you are a backupanytime client, please contact us
immediately. Our first action will be to establish if
the data you have issue with is part of your scheduled
online backups. If it is and the most recent copy is
recent enough we will estimate a time to full functionality
and you can report this to interested parties and get
yourself a coffee.
If you are not a backupanytime client, check your own
offline or online backups from a different system to
the one at issue. If you do not have backups on or offline
or if they are not recent or complete, seek data recovery
expert assistance. Do not try to retrieve the data on
your own unless you have considerable experience in
the area of data recovery. Any failed attempt could
worsen the situation or completely jeopardize any possibility
of recovering your data.
Call them without delay. Ensure your intended
suppliers are data specialists. Inform them of all relevant
information including any human error or failed recovery
attempt. Your provider will be on your side. Do not
try to cover yourself. The politics are a different
issue. Your aim should be to recover the data.
There are a number of levels to the degree of work and
associated success rates when recovering data.
- Accidental (or intentional)
file deletion.
This can relate to individual or group of files or
folders which may have been deleted for a variety
of reasons, recently or some time ago.
Surprisingly for many people, accidental file deletion
is not the worst type of data loss scenario. It is
actually quite difficult to completely delete data
from a computer. When you action a delete, the data
is not actually deleted (typical computer surprise)
but the system is told that that area of the drive
is now available if needed and the data you chose
to delete is no longer visually indexed. So, if you
accidentally deleted a file, your chances of recovery
should be good but are never certain. The period of
time since deletion, any extra efforts to make the
data unrecoverable, system activity and new software
loading will all impact the recovery process, procedure,
time requirement and likelihood of success.
- System damage.
If this pertains to the computer not starting at all,
there is a possibility of the hard drive (the hard
drive is a small device inside the system, not the
"computer box" as commonly believed) being
ok and readable from another system.
If however the hard drive itself is damaged as indicated
by zero drive activity, excessive hard drive noise,
hard drive clicking sounds, hard drive whine or hard
drive starting and stopping then you need to alert
your provider to this as each attempt to start the
system could damage it further. In this type of scenario
your chances of recovery are not at their highest
but the issue may be sortable. It will however involve
time and cost.
- System stolen.
Apologies in advance for stating the obvious but if
you have no backups and the source system is not available
to you, there is little a data recovery specialist
can do for you. You have the added very serious problem
that not alone do you not have your data, but some
morally challenged person or group of individuals
does have your data which may involve confidential
details of your clients. Some systems have a call
home feature which causes your system to report its'
external i.p. address (which can equate to a physical
address with law enforcement support) when connected
to broadband elsewhere. If you have it, it may help.
If you don't, you have a stolen goods recovery requirement
rather than a data recovery requirement.
- Data unreadable.
In this type of scenario, you have not necessarily
lost the data per say but may have become corrupt,
damaged or de indexed. This is not a job for an amateur
and again, any amateur attempt may reduce any or all
possibility of making the data readable again. Common
data unreadable situations are unreadable mail files
such as pst (outlook) or exchange files. They will
need to be backed up in their current state and the
software required to read the files will need to be
loaded on to a new system along with any relevant
conversion software (example, if you wanted to read
exchange files on an separate unplugged workstation
they would have to be converted to a pst) and expert
recovery software.
Backup, backup, backup.
Do or don't, is only a matter of time before one of
the situations above presents itself. If you have a
backup when that time arrives, you will be in a much
stronger position, data wise and politically.
