Another test i did, was to create the vss-snapshot manually on the
windows-host and then copy the data from the manually created
vss-snapshot-directory C:\TEST\C:
create-snapshot.ps1
$vss = [WMICLASS]"root\cimv2:win32_shadowcopy"
$vsssnapshot = $vss.Create('C:\', "ClientAccessible")
$vssshadow = Get-WmiObject Win32_ShadowCopy | Where-Object { $_.ID -eq
$vsssnapshot.ShadowID }
$vssshadowpath = $vssshadow.DeviceObject + "\"
$vsssnapshotid = "$vssshadow".Split('=')[1];
$vsssnapshotpath = "C:\TEST\C"
New-Item -ItemType Directory -Force -Path $(Split-Path $vsssnapshotpath
-Parent) | Out-Null
cmd /c mklink /J $vsssnapshotpath $vssshadowpath | Out-Null
Write-Output "$(Get-Date -Format "yyyy-MM-dd HH:mm:ss") DEBUG:VSS ID:
$vsssnapshotid"
Write-Output "$(Get-Date -Format "yyyy-MM-dd HH:mm:ss") DEBUG:VSS
Mountpoint: $vsssnapshotpath successfully mounted"
job.conf
...
ClientRunBeforeJob = "powershell.exe -noprofile -executionpolicy bypass
-file C:/scripts/create-snapshot.ps1"
...
The job runs without any errors or warnings. All files were able to be
backupped. One more thing i noticed:
Bareos creates a snapshot will following attributes: vssadmin list shadows
...
Typ: Backup
Attribute: Differential, Auto recovered
...
while the manually created snapshot contains following attributes:
...
Typ: ClientAccessible
Attribute: Persistent, Client-accessible, No auto release, No writers,
Differential
...
Any input is welcome
Best,
Timo
