3 The method of performing tape backups can be a factor in slow

backup operations. Data sent to the tape drive over a network

connection and delays in data transfer over a network connection

can cause backups to slow down.

To determine whether the method of performing tape backups is a

factor:

a Use StorageCare Sage xTalk to perform a diagnostic write/read

test.

Caution: The read/write test will overwrite any data on the

tape. Always use a new/blank or “scratch”

cartridge for diagnostic read/write tests.

The diagnostic write/read test evaluates the connection

between the tape drive and the SCSI controller and removes the

network data transfer and the backup software from the

performance evaluation.

b When the test finishes, determine the megabytes per second

data transfer rate to verify that the tape drive is performing at

an acceptable rate.

IF you believe that the

read/write transfer rate is .

. . THEN . . .

too slow, use StorageCare Sage xTalk

to perform a trace buffer

retrieval.

Send the diagnostic output

file to Technical Support for

evaluation of the SCSI bus

condition.
