To the Webroot developers: PLEASE a) provide a way to disable "Backup & Sync" on the Mac, and/or b) use log rotation for your logging.
I've been fighting a problem for MANY weeks where my Mac seems to always be running hot, fans always continuously on, CPUs almost pinned. I was actually starting to research getting a new laptop because this one really wasn't usable anymore - _something_ was just killing it too badly.
I finally traced a big part of the problem to Time Machine, but why was Time Machine backing up 160+ MB of changes every hour, even in the middle of the night when I'm wasn't using the machine, and hadn't used the machine for days? And because my Time Machine backup goes over a wireless network, over a PowerLAN bridge, to a Synology NAS, that 160 MB backup takes 25-35 minutes every time it runs, so every hour, 24x7, and it seems to throttle my machine while it's running.
Apparently most of the culprit is the "Backup & Sync" log file.
I don't use "Backup & Sync", but every 3 seconds since I installed Webroot 6 months ago, it has been logging the message "NoCredentials or NeedsAuthentication" (among other things) to its log file. Every 3 seconds.
The log file is now 120 MB in size -- in barely 6 months -- and because it changes every 3 seconds, every single Time Machine backup backs it up. Every hour, for 35 minutes. (Of course, I'm sure the backing up of this 120 MB file, every hour on the hour, has also pushed a large amount of useful files OUT of my real Time Machine archives as space ran out in there, but that's another problem.)
So ... I've now excluded the "Webroot/BackNSync/log-BnS-FE.txt" log file from my Time Machine backups, and my machine is once again usable.
However, since I don't use "Backup & Sync", and don't plan on using it, is there any way to completely disable Backup & Sync on my Mac?
Also as a suggestion for the developers, rather than using one massive and ever-growing log file, could the log file be rotated periodically instead? Using one single log file will cause this same problem for anyone doing any sort of incremental or differential backup. My "remote Time Machine" backup situation just made it more obvious and painful.
