WFH: Code42 and Home routers/NATs

    Folks:
      As the WFH wave builds here at Cornell, I've gotten some scattered reports of the Code42 app driving home routers hard.  I suspect the root cause is the fact that most home networks are heavily weighted toward download (ours in 768K down/128K up - and no, we don't have fibre or business class) and if the Code42 app detects a large file or large number of files to backup, the resulting backup does get throttled at the router (since the link between the router and the device isn't throttled)

      We are aware of the Code42 low bandwidth recommendations: Use the Code42 app with lmited bandwidth
     but if this is something we need to get ahead of in terms of communicating to Org Admins, I'd like to do so now.

      Have others gotten reports of this?

     Thanks in advance!

    Uh, make that 21.0 Mbps down/11.7 Mbps up according to our ISP (Spectrum) speed test- not quite as biased as DSL used to be, but still biased

    Hello Bob,

    Incremental backups should be quite small, so I'd recommend confirming Code42 is actually the culprit. You can see definitive information about how much data we are actually sending and when in the clients history log.

    03/18/20 07:57AM [<redacted>] Completed backup to Code42 Cloud USA West in 0h:00m:02s: 5 files (3.70MB) backed up, 8.10KB encrypted and sent @ 336 bps

    We could absolutely apply app layer throttling to limit the data sent, or change backup times to off hours, limiting the amount of data being sent during the work day. (note, if you stop backups during business hours, you must ensure users leave their machines online after hours to ensure the backup happens).

    There are a lot of folks working from home right now, and to help there's a newly authored support article that outlines the options to limit the impact Code42 has.
