Do full file backups make sense?

1

Perhaps this is obvious for everybody but in UrBackup, Full backups don’t seem “required” for incremental backups to work. (some backup products only write the differences between the last full and the current state, but you will need that last full backup to reconstruct your entire system).

With UrBackup even an incremental backup will backup all files available to it.

So why use a full backup? Is this unnecessary space? Or will a full backup just recheck all files, but not necessarily store tons of duplicates?

I take your point. As all the magic uses linking of some shape or other - then what you argue is fine - up to a point. For those of us who’ve been in the IT game since the early 70’s - there is Murphy’s law. So…I have a max of 2 full’s that are taken once every 60 days and all the rest are daily incrementals.
