Notes on Using Batch Files or Shell Scripts

When multiple backup/restore operations are executed at the same time by using batch files or shell scripts,
the LT20 S2/LT40 S2/LT60 S2 may become busy due to multiple NetBackup robot operations. This may cause
any backup/restore operations to fail. Use of the NetBackup Administration Console is recommended for
multiple backup/restore execution.
To execute multiple backup/restore operations at the same time by using batch files or shell scripts, set an
interval after a mount operation or an unmount operation is complete. The recommended guideline for the
time to set as the interval after a mount operation or an unmount operation is the total number of tape drives
multiplied by 120 (in seconds). To set the interval, use the sleep operation or another operation.
In addition, perform the settings that are described in
