Length of RTP data storage

How long is RTP data stored - both in RTP and Google Analytics? Is it 90 days like anonymous lead data?

For example, if I want to compare visits by industry to a specific page in GA, will I be able to compare YOY or can I only compare the last 90 days? What about creating a segment that uses visits to a specific web page - is there a limit to how far back you can look?

Thanks!
