Recommended Time between Syncing

I primarily use DevonThink on a desktop but also have a laptop I use when traveling. DevonThink is installed on the laptop and syncing is working fine. I sometimes go some months without using DevonThink on the laptop and am wondering if there is any risk that going too long without syncing could causing a sync problem. (ie should I set up a reminder and sync monthly or so whether I’m using the laptop or not?)

Just want to be proactive and not find out the hard way! Thanks!

What sync method are you using?

I am using Dropbox.
