Ok, now I'm convinced. This bitrot shit is real. Recently watched an ripped ep of a show. Bout halfway thru I noticed it fuck up a bit. This ep/show has been on my server since 2015. At the time I Ripped it, it was perfect. Source was a DVD. Checked server SMART to see if maybe a drive was failing, no luck, drives all report healthy. Then I tried to open a few dvd iso's that also date to 2015. All reported bad navigation structure in DVD shrink. Which again, back then they were all perfect. Hope to hell I can pull a good copy from backup, otherwise I'll be taking a nice afternoon digging in my storage room finding dvds.I do have a Freenas box but it's the last link in the backup chain. Any bad data from the server is on it's drives to. Fucking hate it. Got 4TB of media, half of it is rips of my DVD's/CD's. Other half is from torrents. Either way it'll take a long time to redo it all if it comes to that. Never again. Gonna upgrade my main server to Server 2012/2016 and ReFs. Put an end to this bitrot shit once and for all.

Yup, I don't know why you didn't think it was real.
Why didn't your torrent client detect it? You're not using a freetard client, are you?

stupid ass bitch, do freenas with zfs and at least one-disk redundancy
Only 3 years? It sets in that quick, huh?
>dvd/CD rips
Oh sorry op I time travelled to the near distance future of 2018 where we have x265 and 4k uhd
Guess I'll get back in my time machine and go back to the late 90s
I need a program to detect this so I can restore from backup if something rots. I can use md5sum to get sums, but I only want to test files that haven't been modified.
THEY HAVE FILESYSTEMS THAT WILL DO THIS FOR YOU. ECC RAM + ZFS, NIGGA
DVD rips are going to be higher quality than whatever compressed shit you download from the net.
I'm too poor for that.
the only reliable way is to check by hand all the files that have changed and are gonna get overwritten in the incremental backup
You don't even really need ECC RAM, either.
what does 4K UHD or x265 codec have to do with any of this? You realize Blu-ray is 1080p and UHD blu-rays exist right? I have a shit load of CDs, DVDs, blu-rays, etc. Ripping them and ensuring they don't suffer from bitrot is a very valid concern.
Not even OP, but you just sound retarded.

no shit buddy

Nowhere does op mention the year he ripped it, only that he has it.
Ass.
What am I looking at here?
the top half is the actual jpg and the bottom is two different images from different sets which got mashed into it
Install gentoo with btrfs.
did you really think your precious dvd's are safe?
btrfs > zfs
meh, just keep changing hdds every few years.
takes literally 2 seconds to ctrl+a, ctrl+c, ctrl+v.
as cheap as it can get.
>inbr what kind of special sophisticated faggot i would be if i had to manually copy paste all that tbs of data to a different hdd for a few minutes?
New hard drives dont protect against bitrot. Cosmic background radiation is still going to randomly flip a few bits every so often.
Thats not bitrot then its glitch art boii OP's is actually sexier though
POST MOAR
>Cosmic background radiation
meh, i get bored of the same old porn soon enough anyway.
this way i have the incentive to delete the old porn and download some new one.
also, we have entered the era of streaming, who needs to hoard TBs worth of data now anyway?
OP again, well it's as I feared. Checked the main backup, which is over a yr old. The bit rot extends into it as well. So that means the Freenas archive box (last link) is also fucked since it came online after that backup was taken. Reason I'm going with ReFs is cause most of my software is windows based. It all just works as it is. Was planning on overhauling my server the next time a drive kicked (new case/higher capacity yet fewer drives/upgraded os) but the bit rot problem has to be addressed now before it spreads. I'm not to worried about the ISO's, still have the physical disc. It's the video rips that worry me. How bad is the problem, is it confined to single or few files, that sort of deal.

You're using a version of Windows Server as the main backup software? I have read about data corruption issues in Server 2008 and WHS, don't know if that's relevant.

No, the server data backup is done by Macrium Reflect. In addition the server's data volumes are in raid 1 and 5 configuration. Been using a UPS on it since 2015. The data itself (all of it not just videos/music) has been around for 20 odd yrs since 1997. I've migrated it from build to build.
DVD is compressed using a less sophisticated algorithm (MPEG-2) than most streaming video on the web nowadays, which uses MPEG-4. And it's all in standard resolution which is very low for HD displays.
Well the new OS installed easier than I thought. It found/imported my Dynamic Raid volumes automatically. Now I'm working on setting up Hyper -v so I can run my old OS and maintain existing Users/and Backups. After that is done I'll blow away the dynamic volumes and configure Storage spaces
ok, this sucks, Can't RD into it from my desktop computer. I made sure to enable firewall access on the server and to enable remote connections.
