Jet backup on windows

[dsg]

Hi,

If our server has the Windows Volume Shadow Copy Service (VSS) enabled is it possible to backup JET databases without putting Plastic in to read only mode?

If not are there any other backup options that do not require putting plastic into read only mode?

Thanks,

Hi Dale!

I believe I answered this one using the Zendesk support, but just to let the community know my answer, here it goes:

Well, the VSS documentation says they can run backups even if the files are in use. I didn't try it before, so I can't share feedback, sorry.

I can tell you we use Memory-mapped files for the Jet database files, that might help you to get more information about how VSS or Cobian can handle them, here you have dome documentation:

Best,
