What happens to stubs deleted using Erase Data by Browsing option?

If stubs are deleted using Erase data by browsing option, the subsequent backups will not prune the stubs from the disk. The stubs would still be available in the disk. However, you cannot perform a recall or a restore operation on these stubs.

Can I perform stub recalls or Stub Pruning using File Share Archiver Client?

Yes. You can perform stub recalls or stub pruning on NetApp file server using File Share Archiver Client provided Fpolicy is disabled on the file server.
