Most companies use relational database management system (RDBMS) 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 What happens if after rebooting the server the database doesn’t attach and your backup is corrupt, incomplete or outdated?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 data 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. NetCom’s team of data recovery specialists can expertly assist you in these instances to recover your data.
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 recovery.
Media in database servers suffer from the same failure points as drives in personal computers. Even the best configured system can fail due to:
- Corrupted database
- Torn page detection
- Deleted data (tables, records, system objects) I/O errors in SQL server
- Deleted or corrupted log file
- Database in “suspected” mode
- Unable to restore from corrupted backup file
IS IT POSSIBLE TO RECOVER?
In most cases it is possible to repair the 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?
Third party SQL recovery and utility programs can cause damage beyond our ability to recover the files so it is best if clients don’t attempt recovery with such programs with the original files. For database repair and/or scavenging, it will save time if you can furnish NetCom’s team 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, NetCom International, Inc will contact you for approval. No work will be done without your consent. As soon as you approve the recovery, our technician will continue with the recovery effort by analyzing the database and records, extracting the data and rebuilding the data- base.
