Common Problems
Problem Backup or instant recovery aborts due to VDS problems.
A backup or instant recovery session aborts with the following error.
Failed to load VDS service.
This error can appear as a result of a VDS service crash.
Actions 1. Stop the Virtual Disk Service (VDS):
• Check that Virtual Disk Service is started, stop it using the
command net stop vds or via the Control Panel.
• If the above step does not help, stop the Virtual Disk Service by
terminating the process vds.exe using the Task Manager. VDS
will be started automatically as needed.
• Alternatively, you could also log in to the system again and check
if the system requests your confirmation to stop a crashed VDS. If
it does, reconfigure the debugger to launch automatically to avoid
similar problems in the future. This can be done by setting the
HKLM\SOFTWARE\Microsoft\Windows
NT\CurrentVersion\AeDebug value Auto to 1.
2. Check your configuration.
Successful Application Recovery Manager backup or restore
completion is influenced by a number of factors imposed by
non-Application Recovery Manager components, including Microsoft
Exchange and VSS. One of the factors is timing, which in turn is
impacted by environmental conditions such as I/O loads, storage
device activity and concurrent Application Recovery Manager actions.
To inhibit potential issues, it is recommended that you balance
Application Recovery Manager activity across the available activity
or maintenance window. If you encounter issues, review and possibly
reduce concurrent Application Recovery Manager activities such as
concurrent backups or restores.
