Only incremental backups?

I’m evaluating UrBackup for my purposes and I had a question. I’m going to be backing up a very large data set that’s my take several weeks (running 24/7) to do a full backup. As such doing full backups every few months doesn’t really make much sense. Is it possible to do only incremental backups after the first full backup? Are there any downsides to this (i.e. data corruption, etc)?

Thanks

Yes. Downside: Obviously unchanged (as determined by the operating system) files won’t be read and inspected for differences anymore.
