I have a Synology NAS. I guess it’s fine. But the real problem is what software to backup my win10 desktop to? I tried EaseBackuo which was terribly documented and the UI made no sense (made in China I think). So I gave that up, abs bought Acronis True Image. This software looks nicer but works horribly too. It has intermittent spells of failing backups telling me only “failed to lock file”. The support team has just been giving me a run around for 2+ months. Provides no concrete details or solutions despite me sending them the 35mb log files that Acronis generates. It’s all shameful. Is there a decent software for this????
