Wbadmin Schedule backup to network share

Windows Server Backup allows you to create backups to internal hard drive or external hard drive, and shared folder over NAS network is also supported, but creating scheduled backup to shared folder in Windows Server 2008 is not supported.

To get rid of this problem, you can use Wbadmin start backup -backupTarget command that can create schedule backup to network share.

For example: To backup C: drive and recovery partition to shared folder, you can use the following command. wbadmin start backup -backuptarget:\\192.168.0.221\Public\backup –include:C:,\\?\Volume{95b895b8-0000-0000-0036-223470000000}\

Wbadmin Backup

The problems to use Wbadmin start backup backuptarget

The command line wbadmin start backup solve the problem of schedule backup to shared folder. However, here comes other problems:

The location for backup is a critical volume error. When specifying local disk or volume using its drive letter or GUID-based path as the wbadmin backup target volume, you cannot select any volumes included in the backup. At the same time, you will receive  error message saying that the location for backup is a critical volume or something similar.

Backup will be overwritten at the next time. When specifying a backup to shared folder, the next backup will overwrite the previous one before even starting. Therefore there is a risk that you may lose all the backups if the running backup fails.

Few tricks to Wbadmin start backup backuptarget

Seemingly, configuring a backup using Wbadmin start backup has many restrictions and limitations. Luckily, some of them, there are solutions or workarounds to get over with.

1. Modify registry line before backing up to critical volume.

Windows backup utility won’t allow you to backup to critical volumes and throw out error message like “Error -the location for backup is a critical volume”. To solve this error, you can choose to modify some lines in Registry that allows you to backup to critical volumes.

Modifying things in the registry incorrectly may lead to serious status. This is not recommended unless you strongly need to save backups to critical volumes.

2. Create scheduled backup to NAS shared folder using scheduled task. 

To create bare metal backup to a network shared folder at 00:00 every day and name it as DailySystemBackup, you can use the syntax - SCHTASKS/Create/SCDAILY/TN/RL HIGHEST/ST/TR. Type as follows:

SCHTASKS/Create/SCDAILY/TN DailySystemBackup/RL HIGHEST /ST 00:00 /TR "WBADMIN START BACKUP -backupTarget:\\192.168.0.221/Public/Schedule -allcritical -include:systemstate -quiet >> C:\backupLogs.txt" 

Note: But if you want to create a weekly schedule backup or less frequent backup task, you can use the syntax: SCHTASKS /Create /SC WEEKLY /D/TN/RL HIGHEST /ST/TR.

3. Create incremental backup to network share by virtual hard disk. 

To avoid being overwritten by the next backup, you need to make Windows think the shared folder as a local disk. You can create a virtual hard disk (VHD) in the shared location and initialize and format with NTFS, then use it as backup target location to run incremental backup.

To create virtual hard disk in the shared location, you can use the syntax - create vdisk file=[] maximum=[disk size]. Type as follows:

 create vdisk file=\\192.168.0.221\Public\backup\newdisk.vdh maximum=15000

Create Vdisk

Note: Windows only supports keeping one scheduled backup, and the scheduled backup will fail if there is a backup running when the scheduled time comes. If you do not content with these workarounds, you can try third party software like AOMEI Backupper Professional.
