Database Recovery
Most companies use RDBMS (relational database management system) and store
their data in SQL databases. What happens if after rebooting the server the database
doesn't attach and your backup is corrupt, incomplete or outdated? Have you ever
had a drive containing SQL database crash and the files were recovered
by a data recovery company but the SQL database is corrupted? One unreadable sector
inside a SQL database will not allow the file to attach. SQL recovery
from drive failure is, more often than not, a two-stage process. First, the physical
data (raw sectors) must be recovered in order to gain access to the logical data.
If the database will not attach to SQL server then the second stage
is SQL data recovery . Sacramento Data Recovery will quote you pricing
for each process.
Media in database servers suffers from the same failure points as drives in personal
computers.
Even the best-configured system can fail due to:
Corrupted database MDF file
Torn page detection
Deleted data (tables, records, system objects)
I/O errors in SQL server
Deleted or corrupted LDF log file
SQL Database in "suspected" mode
Unable to restore from corrupted SQL backup file
Is it possible to recover? In most cases it is possible to repair database
to an attachable state. If we are unable to repair the database to a point to
where it will attach, then we will recover as many tables and records as possible
for you with our specialized software tools. This recovered data can then be merged
back into an empty database that your front end application will work with:
Getting Started: If the failure mechanism is hardware or file system corruption,
then we would require the original media to be sent to us. This is because file
fragmentation can scatter pieces of the database and log file all over the media.
These pieces must be collected and reassembled so we can start our analysis. If
the database was corrupted by some other means then a copy on any media will do.
What can you do to help us? Third party SQL recovery and utility
programs can cause damage beyond our ability to recover the files so please don't
try anything on the original files. For database repair and/or scavenging,
it will save time if you can furnish us with the database structure (perhaps an
empty database or backup) and a list of prioritized tables.
After determining what steps will be necessary to complete your recovery, we will
contact you for approval. No work will be done without your approval. As soon as
you approve the recovery, our technician will continue with the recovery effort,
by analyzing the database and records containing your data. This data can then be
extracted and the database rebuilt.
