Join Martin Guidry for an in-depth discussion in this video Copy-only backups, part of Microsoft SQL Server 2014: Backup and Recovery.
- [Voiceover] Now let's talk about copy-only backups.…In SQL Server, a copy-only backup…is a special type of full backup.…It's different than other full backups…in that it does not become the base…of the next differential backup, so a differential backup…is always based on a full backup and what it backs up…is the changes since that last full backup,…but if we do a copy-only backup,…it does not become the base of the next differential backup.…
The next differential backup will still…be based on the previous full backup.…It's somewhat unusual that you would want to do this,…but if you're taking backups on a regular schedule…and writing them all to the same media…and then for some reason you need to take a full backup…that's not part of that schedule…or will not go onto the same media,…you might wanna use a copy-only backup.…If not, you could find yourself, when doing a restore,…of being unsure of which full backup…is connected to which differential backup.…
Performing the copy-only backup is very simple.…We'll do a few quick demos here.…
