Database Recovery

Database files that are inaccessible or missing are caused by one of two things: a failure in the data storage device (hard disk, SAN, DAS/RAID) or damage to the internal database that prevents row data from being accessed.

In either case, Ontrack® Data Recovery services provide the expertise and recovery applications to extract and reassemble the information that resides inside of a database file. Kroll Ontrack engineering teams have certified developer status with Apple, Microsoft, Sun, and VMware. This provides the best recovery solution possible for your critical database applications.

Database Recovery Process

The recovery process for database files includes four stages. A successful recovery of these types of files requires a verification of the storage device or system and the file system that contains the database.

Data recovery steps Description
Step 1 Target LUN (SAN or NAS), iSCSI* LUN identification, low-level DAS/RAID are verified at block level.
Step 2 Volume file system indices are checked for meta-data-to-data stream integrity.**
Step 3 Database file integrity is checked.
Step 4 Database listing of all recoverable tables and rows is completed.

*iSCSI LUNs are reliant upon the SAN's internal file system to manage the data. Data loss within this type of logical storage may require access to the SAN's volume where the iSCSI files are stored.

**Target volumes that reside within virtual disk files are dependent upon the hypervisor's datastore file system to manage the data. Data loss at the hypervisor volume level or within the guest's virtual disk file may require additional engineering effort to complete the evaluation.
