If you are planning on hosting a Pure Backup Repository on a NFS share, please make absolutely sure to only use NFSv4.

Pure makes use of SQLite internally and network shared file systems, NFS in particular, are known to have problems with implementing file locking. Particularly, NFS versions prior to v4 do not implement real server side file locks, using instead a Network Lock Manager (NLM). This can lead to data corruption and access deadlocks with SQLite databases even if there is no actual concurrent access to the database.

With the NFS version 4 protocol, the support for file locking is part of the NFS protocol.
