Get a resource representation of the VM guest OS directory.

[Mardock]

Hi,
I try to get a resource representation of the hierarchy of the VM guest OS file system within a VM backup ( Veeam REST API v8.0.0.917).


I'am using the following HTTP request: GET /catalog/vms/{VMNAME}/vmRestorePoints/{ID}/guestfs/{FILEPATH}?action=listAll


I have notice that if I query a path like "C:/Users" or "C:/Windows" the server returs correct response.

Examples:
GET /catalog/vms/{VMNAME}/vmRestorePoints/{ID}/guestfs/C:/Users?action=listAll
GET /catalog/vms/{VMNAME}/vmRestorePoints/{ID}/guestfs/C:/Windows?action=listAll

But, if query a path of livel 2 like "C:/Users/Administrator", "C:/Windows/System32" or level 3 like "C:/Users/Administrator/AppData" (and so on ... )

Examples:
GET /catalog/vms/{VMNAME}/vmRestorePoints/{ID}/guestfs/C:/Users/Administrator?action=listAll
GET /catalog/vms/{VMNAME}/vmRestorePoints/{ID}/guestfs/C:/Users/Administrator/AppData?action=listAll
GET /catalog/vms/{VMNAME}/vmRestorePoints/{ID}/guestfs/C:/Windows/System32?action=listAll

then the server returns the following error:

Code: Select all
