Validating the Atom database or recovering from an
inconsistent Atom database
The Atom embedded database is self-cleaning. Normal operation will add or remove
database rows as files are added or removed from monitored volumes. For volumes that
are no longer being monitored, use the following instructions to validate the database.
You can also use these instructions if the Atom database has become inconsistent (for
example, when a volume is monitored and at some future date removed but not returned
to its original state).
1. Purge rows that are no longer valid by using the following command, substituting
the storage bin volume letter for storagebin_volume .
atomadmin -p storagebin_volume
2. If desired, you can re-evaluate files eligible for deduplication by using the following
command, substituting the volumes to be evaluated for volume_list .
atomadmin -t volume_list
Recovering from a corrupted Atom database
If the Atom embedded database has become corrupted, it can be re-created manually.
1. Stop the Atom File-Level Deduplication Service using the Windows Service
applet.
2. Delete the files DT_SIS.sdf and SisSupportDB.sdf from the \Program Files\Storage
Works\Storage Mirroring\Atom\Data directory.
3. Restart the Atom File-Level Deduplication Service. Atom will now begin monitoring
the same volumes as before the corruption.
