Backup Concurrency in the same database

Antonios Chatzipavlis
Monday 19 June 2017

Οι ερωτήσεις σχετικά με τα backups στο SQL Server είναι πάντα από αυτές που δέχομαι συχνά. Μια από αυτές τις ερωτήσεις είναι τι γίνεται στις περιπτώσεις που ταυτόχρονα συμπίπτουν δύο διαδικασίες backup είτε του ίδιου τύπου είτε διαφορετικού.

Στο παρακάτω πίνακα δείχνω τι ακριβώς γίνεται:



Already running FULL DIFFERENTIAL LOG
When Full Backup is running Blocked Blocked Allowed in all versions above 2005
When Differential Backup is running Blocked Blocked Allowed in all versions above 2005
When Log Backup is running Allowed in all versions above 2005 Allowed in all versions above 2005 Blocked
