An IT firm are currently setting up an automated backup system for one of my clients.
They are setting it up to do backups several times a day, including during working hours.
I pointed out to him that I'm unhappy about backups being done whilst the backend file is open.
This was his reply:
"The Symantec backup software use Microsoft Volume Shadow Copy Service backups - this is a point in time snapshot of the files - so it doesn't actually backup the file itself, it takes a copy of it. This ensures the no lock-ups or database corruptions."
Is he right? Or is there still a risk of corrupting data?
