Create a backup job using wbadmin specifically with the -backuptarget
switch i.e. -backuptarget:\\servername\sharename
Unfortunately, wbadmin
requires the share to be a UNC path, so other network storage filers are excluded. But really, did you want to push your backup across a network using FTP? Of course you didn't. When asking yourself "Can Windows backup to $n storage service?" reverse the question and ask "Can $n storage service be presented to Windows as a local drive or UNC path?" If the latter question can be answered in the affirmative, then you can use wbadmin
to backup to it either locally or across the network.
If you're more into PowerShell (which anyone administering Windows boxxen should be), have a look at how to add PowerShell cmdlets that can manage Windows Server backups. There's quite a gamut of them:
Add-WBBackupTarget
Add-WBBareMetalRecovery
Add-WBFileSpec
Add-WBSystemState
Add-WBVolume
Get-WBBackupSet
Get-WBBackupTarget
Get-WBBareMetalRecovery
Get-WBDisk
Get-WBFileSpec
Get-WBJob
Get-WBPolicy
Get-WBSchedule
Get-WBSummary
Get-WBSystemState
Get-WBVolume
Get-WBVssBackupOptions
New-WBBackupTarget
New-WBFileSpec
New-WBPolicy
Remove-WBBackupTarget
Remove-WBBareMetalRecovery
Remove-WBFileSpec
Remove-WBPolicy
Remove-WBSystemState
Remove-WBVolume
Set-WBPolicy
Set-WBSchedule
Set-WBVssBackupOptions
Start-WBBackup
It should be noted that the PowerShell cmdlets do not support backing up to removable media. You'll need to fall back on wbadmin
for that. They do, however, support network targets.
