Best practices for setting up Dell VTL Container or NetVault Backup native virtual tape library (nVTL)

Technical setup and conﬁguration DR VTL Container -- best practices

This section highlights key conﬁguration and setup best practices to add the DR Series

appliance for the use with native VTL container instance(s).

General setup and conﬁguration DR VTL Container -- best practices

For additional details on the following prerequisites, refer to the manufacturer’s

documentation.

• Ensure that cabling is conﬁgured correctly.

• Conﬁgure interfaces, protocol, and addressing.

- Conﬁgure the networking infrastructure to support jumbo frames (MTU=9000).

• Make sure that you have a preconﬁgured system to run as the NetVault Backup Server

• Make sure that you have a DR Series appliance preconﬁgured for use with the following

attributes established:

- Proper network connectivity with IP address or DNS name of DR Series appliance.

- DR Series appliance(s) conﬁgured with the appropriate DR VTL container.

- All authentication requirements fulﬁlled such as domain name, user name, and

password for users set up on the DR Series appliance.

• Create NetVault Backup Server users who have full read/write access to the container. This

is a requirement for NetVault Backup to be able to manage the conﬁguration items and

respective objects created within the applicable container during backup, provide access

during recovery, and perform deletion upon retirement.

DR VTL Container setup and conﬁguration -- best practices

Due to various factors such as data-set size, data-set iteration or count, retention period,

and change rate, it can be dicult to determine the best VTL size and conﬁguration for any

deduplication situation. One of the best practices is to size the VTL to no more than 10x the

physical available disk space or to assess how much data the customer has to back up and

the required retention periods for each set of data. Ensure that neither of these guidelines

is exceeded when you create the virtual media for the VTL, and set the drive count to equal

the number of desired simultaneous jobs or data streams without exceeding the maximum

guidelines set forth by the vendor.
