When using dump, a .snap directory is created in the partition being dumped.
I have searched for the reason this directory is created but haven't found any information on its purpose.

I have monitored the .snap directory during a dump and I have never seen any files appear in during the dump so I was wondering what the purpose of this directory is.

When the dump is complete is it OK to delete the .snap directory or is it used as a marker of some kind?

Thanks
