A new EMC Avamar customer requires the ability to perform tapeout from Avamar to their existing
Symantec BackupExec tape backup application. They want to know how the tape metadata is
managed. Where is the tape metadata stored in this Avamar tapeout environment?
A.
In the tape application being used
B.
In the PostgreSQL database of the control node
C.
In the PostgreSQL database of the transport node being used
D.
On the Avamar utility node in the PostgreSQL database
An ADT control node is a Linux-based virtual machine that controls the operation of ADT. It
hosts the ADT Framework and Application: a user interface used by an administrator to
schedule and run transports and restores. It also hosts the PostgreSQL database that stores
metadata of files that have been transported. This database is used during recovery to locate
which tape backup contains the requested files. Also, security logging is performed by the
control node.

Since the stripe files that are written to tape contain a mix of deduplicated data from
multiple original files, the tape server is not aware of the files that make up the backup. For
this reason, metadata is generated so that ADT can track the individual files in this transport
operation. The transport node walks over the clients and backups in the replicated data and
uses this information to populate the PostgreSQL database on the control node.
