where IP_address is the IP address of the storage system. If you do not see Reply from..., the

• If the storage system already exists, select it in the list of backup locations and then click Remove.
Then click Add to add it again. This resets the settings in the iSCSI initiator which might be causing the

where IP_address is the IP address of the storage system. If you do not see Reply from..., the
problem is with your network.
• Make sure that the backup has not been deleted on the storage system by checking the Backups
page (as described in “Managing Backups” on page 61).
If it has been deleted, remove protection (as described in “Removing Protection” on page 122) and
protect the disk again (as described in “Protecting Your Disks” on page 98).
• If you changed the name of your computer, the storage system will not recognize it any longer.
Remove protection for all your disks or partitions (as described in “Removing Protection” on page 122),
delete the old computer name from the storage system (as described in “Deleting a Client” on
page 64), and then protect your disks again (as described in “Protecting Your Disks” on page 98).
A backup did not occur at its regularly scheduled time.
• Check the schedule (as described in “Changing the Backup Schedule” on page 106) to confirm that it
is correctly configured.
• Make sure the computer is powered on during the scheduled backup time.
• Make sure the storage system is powered on during the scheduled backup time.
•On the Status page, make sure that the Status is Normal. If protection is stopped (for example, if you
recovered the disk or recovered a different partition on the same disk), backups will not occur until you
resume protection by clicking Back Up Now.
Note: When authentication errors occur, invalid backups might be created on the storage system. To
ensure that you do not use up disk space unnecessarily, be sure to delete any extraneous
backups on the storage system (as described in “Configuring Remote Boot” on page 63).
Compare the Backup disk ID on the Status page in DiskSafe Express with the Backup Disk ID
on the Backups page in the Web User Interface to determine which backup is actually being
used.
