Hi,
I'm trying to find how snapshot backups works.
I know that custom backup applications can connect to sql server through VDI API and send a backup instruction with the "with snapshot" parameter to take a special backup.
I found some information about using this kind of backup to take very quickly backup in heavy used environments. It's possible to create instantaneous copy of the data, some times taking advantage of mirroring. That's the point.
How this instantaneous copy of the data works ? I understand if it uses mirror, but some backup software, like symantec net backup, uses this kind of backup even without mirror.
I found some information in this document : http://technet.microsoft.com/en-us/library/ms189548(v=sql.105).aspx but I still would like more details about how the snapshot backup works.
Are there more detailed documents about this ?
Thank you !
