We make in our company some times differential backups. The default file extension in the maintenance plan wizard is for this type of backup .BAK. So my question is: Is there any industrial standard about the extension for differential backups like e.g. .dbk or what ever?

There is no standard I'm aware. Just use whatever makes sense to you and make sure you stick to that naming convention.

In my case I've always used .bak and I just use <full_dbname_datetimestamp>.bak or <diff_dbname_datetimestamp>bak as a naming convention.

There's no standard. In fact, I'd probably just leave the extension as is and rename the file as the other poster did.

Typically:

.dif = differential backup
.fil = filegroup backup
.trn = tranlog backup

as most people follow MS's lead, as they did with .bak, .mdf, .ndf (silly, imo, why not .mdf also???), etc..
