I’d also be interested in recommendations that meet the above requirements.
My current work around for my main linux laptop is setting rclone to run with crontab at a time that I know i’ll be online for an extended period (evenings during long homework sessions). I’ve been doing this for several years and have yet to run into major show stopping bugs, and I frequently do checksum verification on my backups.
Yeah, that's sadly not very useful for laptops I manage - people tend to turn them on and off at random times and I had multiple cases where the backups just ended up in hosed state (because the tool got interrupted at a bad time) or just didn't backup for week because the laptop never ran for enough time without interruption after creating a huge file.
