Virtual TapeServer 8.3 Supplemental Installation Guide

Enabling and Configuring AutoCopy and Instant DR | 37
9. Select the Use Secure Transfer checkbox if SSH is configured on the VTS systems and you
want to encrypt the information being transmitted. This transfer method is not necessary if
the connection between the VTS systems is secure or in a trusted environment. The encryption
process used in a secure transfer might cause some degradation in the data transfer rate.
10. Select the All Files checkbox if you want to send all files in the job to the remote system. If
you do not select this checkbox, only the newest virtual tape (determined by the file
timestamps) is transmitted.
Note All virtual tapes within the selected target must be available to be opened and
transmitted when the job is executed.
11. Enter the information for the jobset in the vault, pool, cartridge, and target name fields.
Consider the following information when specifying these values:
l The vault, pool, and cartridge fields define the source of the backup. The target name
field specifies the name of the virtual tape on the target server.
l Specify the vault and pool names exactly as they are on your VTS system. The cartridge
(virtual tape) and target names can be different. Example:
/VAULT01/LIB01
l Specify a single = in any of the fields to specify the same value as the one directly
above that value (previous line, same column). Specify == or * in the pool field to
indicate the same pool as referenced in the source entry, such as /VAULT01/==. You
can specify == for the target name, which indicates to use the same name as the virtual
tape you are synchronizing.
l Instant DR is designed to connect to remote disaster recover sites over a connection
that is much slower than the connection to your host server or the local area network.
It is important to configure Instant DR in a way that maximizes your bandwidth. It is
recommended to use a wildcard for your virtual tape name, such as ARC*. The target
name is the target file name, such as ARCMASTR. Also, you can reduce the amount of
data sent over the connection to the remote site by using a common target name for all
virtual tapes in a pool. Because backup data sets change little from day to day, only
changes are sent to the remote site, thereby minimizing bandwidth.
l Keep the following in mind regarding the target name: If a new generation of a backup
is done on consecutive days, you might rotate through a group of virtual tapes for each
backup on each day and retain previous versions online for several days. The virtual
tape you want to synchronize would be the one most recently created. Each of these
virtual tapes has been generated from the same backup task such that some of the data
remains the same from day to day, and some have changed. If the virtual tapes involved
are named ABC001, ABC002, ABC003, you can use an arbitrary name such as ABCABC to
give to the virtual tape on the remote site.
