> Corruption in file data is arguably worse because it's much more likely to go undetected. Over time, it can propagate into all your backups. When it's finally discovered, perhaps years later when looking at old baby pictures, it's too late to do anything about it This applies to every OS I guess (except with ZFS or BTRFS)? This is my biggest concern currently. I'm mostly using one drive with ext4 that I back up from time to time, what if the files silently corrupt and it propagates to my backups, I wouldn't notice until it's too late probably. I guess rsync wouldn't sync the wrong data unless the files have changed since it syncs based on modification stamps. Investing into a proper RAID or ZFS is "expensive". I'm so paranoid about this I'm probably going to do it at some point.
