Description
When restoring a backup that was written uncompressed (nocompression flag set on the remote volume), the speed with which the backup is fetched from the remote volume can be significantly slower than expected. This happens more frequently on very fast connections.
Workaround
Use compressed backups instead of uncompressed backups.
Fix
Restoring an uncompressed backup from a remote volume is significantly faster.
