In scenarios in the event the mirroring operation is delayed for any cause (network, higher O/O etcetera.) it demand improved time for Actual physical I/O data looking at and thus the PAGEIOLATCH_SH occasions as being the thread must await the data right until the synchronized sign is distributed. Although this often seems much like question blocking, the actual root reason for this lies in issues with synchronization Very poor index management
Take note however, the backup only incorporates the parts with the data file that are actually getting used. For example, a database that is 250GB in dimensions may well only have 50GB of data in it, Therefore site link the data portion of the backup will only be 50GB.
