Monitoring Jobs
Backup Exec's Job Monitor enables you to monitor and perform tasks on the active, sched-
uled, or completed jobs that have been submitted for processing.
The Job Monitor provides the following tabs:
Job List - Displays the active jobs and scheduled jobs in the Current Jobs pane. The Job
History pane displays the jobs that are successful, completed with exceptions, failed, and
canceled.
Calendar - Displays the scheduled, active, and completed jobs in a daily, weekly, or
monthly view.
System Summary - Displays the details of media server, job, alert, device, and media
activity.
The Job Monitor tab can be used to determine if the current backup strategy is meeting the
defined backup window. That length of each backup job can be viewed in the Elapsed Time
column. If the Elapsed Time is exceeding the backup window, changes can be made to the
backup strategy to help reduce the backup window. Changes to the backup strategy can in-
clude:
Switching from traditional backups to continuous backup
Incorporating disk based backup folders for traditional backups instead of targeting tape
directly.
Implementing a disk to disk to tape strategy to support offsite storage of backups

SUMMARY
To supplement the growth in iSCSI SANs, Dell has introduced an iSCSI-to-SAS bridge card
option for the TL-series of tape libraries (TL2000 & TL4000) connected to 1Gb Ethernet net-
works. This offering allows a customer to directly attach a tape backup target to their iSCSI
SAN with little to no degradation in transfer speed, 90 MB/s in most cases. This is the latest
offering in Dell's continuing pursuit of cost-effective and simplified IT solutions for SMBs.
