Why was "Full Backup" changed\removed from interface So you're telling tell me then, that I need to keep my first full backup forever, because it contains old files that never change?
What if i set my retention policy to 15 days from backup date.
Again, by your description, incremental and block level are the same thing. Only backing up changed files. So I just keep backing up ad infinitum because there is no need for retention because clearly I need to keep backups going back months and years because a single file was changed at some point.
Why even have the distinction between incremental and block level since they're both just doing the same thing?
