Microsoft SQL Server 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the database doesn't attach and your backup is corrupt, incomplete or outdated?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. ACE Data Group
Recovery Services 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:
Is it possible to recover?
- 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
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:
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.
