Quickly restoring 1M+ files from backup
https://www.reddit.com/r/programming/comments/1sxy05v/quickly_restoring_1m_files_from_backup/

<!-- SC_OFF -->Back in 2016, we faced a technical challenge implementing a restore for a large number of files (million or more) from a backup.

Neither of the standard approaches worked, so for the solution we had to rely on a couple of undocumented NT internals. <!-- SC_ON --> submitted by /u/axkotti (https://www.reddit.com/user/axkotti)
