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 .

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.
