Data Culling of Large Tape Populations
Data culling is a means of minimizing the data pool to produce responsive data. eMag offers several processes for culling large tape populations that will in turn enable you to produce only the most responsive data at drastically reduced costs.
Header Scans
Header scans produce all available information in the backup header (where available), including the backup date and backup software. This information is useful when backup administrators put copious notes into the scheduled backup sessions or when the customer knows that their e-mail server runs on (for example) NetBackup and their file servers run on Backup Exec. Internal volume IDs are also produced. This is important when there are no external volume IDs or when there are inconsistencies between the internal and external volume IDs.
Server-level Scans
Server-level scans produce everything from the header scan plus a listing of all backup clients (servers) with data located on the tape (where available). The date of a particular server backup is also included for most software types. In addition to the benefits of the header scan, this service is beneficial when you know the name of the server containing data of potential interest. For example, the Exchange administrator may know that John Does mailbox is on server EXCH-US-ATL-006 so we can examine the entire tape population to look only for the presence of that server.
File-level Catalog
File-level catalogs produce everything from the header scan and server scan. The file level catalog additionally provides (where available) a listing of the file size, file name, file path, create data, modified date, last accessed date, MD5 hash, SHA1 hash, session #, and other available information depending on the backup software.
Tape Restoration
We do data restoration to hard drives, DVDs, CDs, or any other storage media to provide you with access to files located on a backup tape. We can also do select includes and excludes based on specifics, such as directory structure, extension type, complete file path, and/or combination of specific characters and wild cards.
