Protect directory-container storage pools by using tape volumes
With Tivoli® Storage Manager Version 7.1.7, you can protect directory-container storage pools by copying the data to container-copy storage pools, where the data is stored on tape volumes.
A container-copy storage pool is a new type of storage pool that provides an
alternative to using a replication server to protect data in a directory-container storage pool.
Container-copy storage pools can be used to repair minor to moderate directory-container storage
pool damage, which includes damaged containers or directories. However, replication is the only way
to provide complete disaster recovery protection for directory-container storage pools. With
replication, you can directly restore client data from the target server if the source server is
unavailable.
Restriction: It is not recommended to use container-copy storage pools for
disaster recovery protection, even if your storage environment is based on a small blueprint
configuration. Repairing an entire directory-container storage pool, even for a small blueprint
configuration, can take several days. Adding more drives or using the latest generation of tape
technologies does not decrease the time that is required for the repair activity.
For information about using container-copy storage pools to protect and recover a server environment in a disaster, and for using container-copy storage pools in storage environments that are based on medium or large blueprint configurations, see technote 7048653.
