For me vss make a snapshot of a volume, like in hyper-v virtual disk. This shnapshot vor windows is a virtual disk file like .vhd (or .vdi). So you can mount this volume file a work with files in the snapshot.
So with Bacula to use vss agent you have to make a vss backup with vss agent by windows and backup this vss snapshot file into Bacula to do what you want if a understand well. bacula deals with the C VSS API, as you would in powershell, it does not directly save the VSS result but uses the API functions to read the snapshot and recover the files stopped at a given time.

In a windows system u can do straight VSS backup which can then be read by VSS tools and chcked/restored, however this not practical when there are many clients even with automation via powershell or other form of scripting. having a backup system to easily check the state of backups and keeping track of them is abetter solution, which is why i am considering bacula As I said i am new to bacula, so it maybe that it is possible to do backups(VSS or otherwise) with bacula that does not use "Volume" files(I am backing up to disk, not a a tape drive) So I guess this is what my questions is, is it possible to get Bacula to do backups with VSS(or even otherwise, simple file copying with or without compression/encryption) without using "Volume" files, i.e the backup files are saved as indiviual files and not all put together in a "volume" file. The volume files seem to be there more for a tape based system, the concept is not really neded if you are backing up to disk Regards /Mehrdad On 2024-04-24 09:23, Radosław Korzeniewski wrote: Hello, śr., 24 kwi 2024 o 08:44 Mehrdad Ravanbod <mailto:mehrdad.ravan...@ampfield.se> napisał(a): HI Thanks for taking the time to answer, but that was actualy not the question I am aware that VSS is for copying files that maybe in Use in windows env., As i said most of our backup is from machines which are windows, both server and client My question is if it possible to get bacula to not put a VSS backup in a volume(which makes it impossible to restore if by VSS tools if something happens to the bacula server), You do not need any vss tools to make VSS backup with Bacula. Bacula will handle all for you. rather save it as it is, that is a sperate file, readable by teh VSS system What does it mean "save it as it is" - I'm not familiar with VSS internal nor advanced usage.
