| Jul 9, 2016 at 18:56 | comment | added | Harry Harrison | @PhilipKendall I agree regarding manual intervention, my point was that if you have a "write-once" scenario and uncorruptible storage, then sync from this, not the other way around. | |
| Jul 9, 2016 at 18:42 | comment | added | Philip Kendall♦ | @HarryHarrison I disagree. I don't want to automatically sync from (e.g.) my NAS to my local hard disk just because my NAS is more reliable - there's still a chance it's the NAS that's screwed up, not my local hard disk (or actually far more likely, I fat fingered something and messed up the file on the NAS myself). Manual intervention is what's needed here - it shouldn't be that common, unless you're Associated Press. | |

@MichaelKjörling their client automatically detects the change to the local copy of the photo and uploads the new version, which is corrupted. Actually, this is an interesting point, because unless the corruption is in a software layer the client won't actually be able to detect the corruption unless you re-write the file.

| Jul 9, 2016 at 14:53 | comment | added | user | "use an online storage service which will handle all redundancy, and file integrity for you."... and their client automatically detects the change to the local copy of the photo and uploads the new version, which is corrupted. Cloud storage is no substitute for good backup policies and some way of actually detecting corruption. Compare What's needed for a complete backup system?. | |
