I need to restore a replica set. Unfortunately my lack of experience as administrator (I'm not) let me with the only solution of restore the replica using the data of the primary db (the only replica element still alive) as a "seed". At the moment I'm copying the files of the primary to secondary PC using rsync (there are 600G to copy). Then I have three questions regarding the restore:
1 - Once the files are copied should I use this data as the dbpath of the secondary?
2- Is the "local" db of primary copied? This may be a silly question but in https://docs.mongodb.com/manual/tutorial/resync-replica-set-member/#replica-set-resync-by-copying the say to be sure that this db is copied along with the data files, and I'm not sure about it.
3- How long it will take to "synchronize" with primary once I start the mongod instance in the secondary PC?
