An Awesome Tool to Prevent Corruption Of Your Most Important Files

Somehow for the first time, the German title and audio track isn’t preselected and I like it but also don’t really know why. I like the real English voice more anyway so it’s not a problem for me. Probably it’s a tweak from uYou+ (the tweaked YT app for iOS I’m using to watch the video).

[@markusTegelane]

A more realistic way to simulate bit rot is to open the file in HxD and fill selection with random values (right click > fill selection > random bytes > OK, you can even do multiple passes if you want). Your method is fine, but you are reducing the number of bytes instead of corrupting them.

Pretty sure it's Parity Archive, because it clearly works like a RAID5/6 would.

[@H4KnSL4K]

I was about to make a comment very much like yours here, so I'd agree 100%. I had lots of usenet servers regularly corrupt parts, so the use of extra parity files was truly essential. I'm also glad we're past that and we have things like BitTorrent (which verifies the data is correct), and filesystems (like Btrfs) that can at least detect corrupted files and give RAID style options (using parity) to recover.

[@bbbl67]

@@H4KnSL4K I don't think it was so much that the news servers corrupted the files, as it was that entire files went missing due to news server retention rules. Of course if you used a huge news server like GigaNews, retention wasn't so much of a problem. But local ISP news servers had tiny storage and low retention rates.

It is important to note that you cannot re-use recovery files. Say you need 50 recovery blocks but you only have 44, you cannot recover it. That is why you can adjust the amount of recovery files and blocks. You could have 4 recovery files each with 50 recovery blocks and send 1 of each to your friends or family, and then if you need more just ask them for the recovery file to get the amount of recovery blocks you need. You can also have over 100% redundancy. It all depends on how important the file you want to recover is to you.

I remember using this more than 10 years ago. I downloaded a big file and it got corrupted during transfer. The guy I got it from just sent me a .par file and he told me to use it to repair the file I downloaded. I was so amazed that the little par file he sent me indeed was able to repair my file. I verified this by confirming the CRC and md5sum is correct. That was my 1st encounter with par files and I was glad to learn about it. Nowadays, I use btrfs file system to resist bit rot and corrupt files. I also do regular backups. Haven't used par files in years but it's nice to know it exists. 🙂

[@vgamesx1]

Winrar is very convient for ease of use but this provides interesting use cases such as creating a par file for an entire 1TB+ HDD and using a much smaller portable drive as redundancy, meaning although not as good as a backup you could cover far more files with that limited space or mix and match, have your photo backup and then give a low percentage redundancy for everything else.

[@estebanod]

Whattttt that is mind boggling, the fact that it works in the first place is crazy

[@intron9]

A quick way to think how error correction algorithms behave is to think about a sudoku game, you can start by having a complete sudoku filled with numbers, and if you delete one number or change it, there are many ways to recover that missing number. You can even have many numbers missing and you will recover the full state, but past a limit you won't be able to do so. I've studied the hamming error correction algorithm at college and it really was similar, the way to recover a bit was to do lots of boolean operations on the data, crossrelated. The most useful thing of these softwares is that the redundancy files are only a fraction of the size of the original document, but they really can fix any error on any of the bits of the source file. The limitation is if you have too much errors, that's when you exceed the "hamming distance" and the program can't recover, but at least it can tell you there are errors. By increasing the size of the redundancy files, you are increasing the number of possible simultaneous correctable errors.

[@johnvriezen4696]

I've never used this, but not mentioned is that this is really for files that don't undergo change. So yes, it works great for a set of media files, but its not going to work on all your Word documents or spreadsheets that you are updating. This can't distinguish between rot/corruption vs. a legitimate update. You'd have to regen the Par files whenever you change anything in your set. Raid storage will do this all on the fly, but if the corruption is done at a high level (in front of a disk write) then the corruption will be taken as a good change from RAID's point of view. Seems to me it makes most sense if you make a backup of a bunch of data, then use Par to make that backup resistant to rot. I'm sure some backup solutions do this automatically.

[@RomeoG39]

Great video, ThioJoe! I have been using PAR2 files for transfers for years, but never even considered that they could be used to protect against bit rot! Genius!

[@US_Joe]

This is essentially how raid works. A disk is assigned for storing parity files (Par) across all drives in % or a dedicated disk for all parity. Depends on the raid level you chose. You are merely emulating this concept on a file basis for backups.

[@JimGriffOne]

@@Xnoob545 SSDs lose data during to bit rot at a much faster pace than spinning disks. It's due to electron traps leaking charge and getting into a new state. Save a coupe of TB of data for a year or two then go back to it later on. There will be countless errors upon reading it, whereas reading off one of the spinning disk backups, very few errors are present (files backed up beforehand). A RAID 5 with spinning disks can handle enough throughout for most tasks (video/audio editing), but SSDs are not the best for professional use without at least some form of backup solution.

[@FunWithBits]

Good idea to share this. This is an awesome tool that I have been using for years.

[@FunWithBits]

To add... creating PAR files are useful when storing lots of files in zip/7z files. Those types of files can lose their a huge chunk of their contents from a tiny corruption since one bit sequence can be used in 100s of files. Using a tool like keeps those small bit flips or corruptions safe and protects the entire archive. The Par files should never be compressed and don't compress well anyway.

[@erichollar5503]

Terrific video. I was just using Beyond Compare the other day to bit-wise scan hard drives with backups I made +/- 10 years ago. So far no bit rot detected. Pretty cool! But this is another great technique for protection.

I used quickpar a while ago one thing I liked is if you needed 1 extra block instead of figuring out which blocks you didn't have, someone with a complete file could create you a new block starting at the last block number that's why the file names have those numbers

[@foobarwild1229]

PAR2 uses Reed-Solomon ECC. It does not matter which recovery blocks you have. It matters only how many you need. You can use any recovery blocks to repair the same number of corrupt blocks. That's why they are dividing the blocks in separate files. If only 10 blocks are corrupt, you only need 10 blocks of ECC data. it does not matter from which par2 file.

I wish there was a way to add this on the filesystem level easily, so the system would just do a sweep of every file on intervals checking for corruption and auto-repairing without needing a RAID array or something else fancy.

I must say that losing a drive is a frustrating thing to happen, especially if the drive has your OS on it. I lost part of my system drive, which is essentially Optane memory, connected with an SSD via RAID. Now, Optane doesn't actually contain any parts of system, it's essentially used for caching purposes. Seemingly unimportant chip, but once it died, system won't boot anymore, and it's impossible to recover. Apparently losing the cache messed Plug&Play drivers up and system won't recognize the drive anymore. The only thing you can do is mount the system SSD into another machine as a non-system disk, backup any data that you don't want to lose, replace or simply just remove the Optane memory, wipe the SSD clean after the work is done, and mount the SSD back in. Then if you removed Optane, you need to reconfigure the drives array to not use RAID (if you do replace Optane with a new one, skip), and then insert install media, and proceed to install fresh copy of Windows onto the drive, then put your data back. However there's something neat about it, and that is that removin Optane frees up NVMe slot, and you can actually insert a new SSD into it. Then you can install Windows into that, and then you don't have to backup your data from the old drive. Although I would still do it, just so you can get rid of the old system partitions and reformat the drive so you can use maximum of it.

Doing fast backup into tar.lz4 or wim is just better. Its like twice the data (duplicates), less the space, at multiple locations, different partition, different drive, external drive, NAS, online storage, different PC... TAR are good old "Tape ARchive" that stores lots of information (like user permissions, hard links, security, etc.), proven multiple times, and are sequential, puts everything into a single file without compression, while LZ4 gives 500MB/sec per core or twice more if PC are last gen. So with new CPU and 16 threads you get like 16GB/sec compression speed, limited by network, disk, RAM, or whatever else, while decompression are limited by the RAM speed. You can replace LZ4 with something else (ZIP, 7Z, RAR, LZO, GZIP, whatever), depending on your needs, like what kind of data and choose between compression:speed ratio. I prefer LZ4 because it gives best ratio across various files, best compression for a given speed/time, it reads fast, extracts even faster, multi threaded, pretty quick and efficient. Google are using Brotli, and its little better compression, but takes way longer. Since its a big sequential backup, old HDDs have problem reading that (just for review the files and extracting a specific one), but for SSD, to read sequential big data, just to see what files are there, like millions of them is not a problem anymore, it just goes trough few TBs of data in second. WIM are new "Windows IMage", made by Microsoft, same as TAR, but it has generic ZIP compression and has some similarities with "image" file (like VHD) so old HDDs does not have sequential problem when reading big file containing millions of files. People are not using WIM because its not yet proven like TAR, but i think its generally good.

Backups should follow the 3-2-1 rule (At least) 3 copies on (At least) 2 different forms of media with (At least) 1 copy off-site

[@SP4CEBAR]

your harddrives do have some error correction built into them, otherwise they wouldn't be as reliable as we are used to

[@ThePowerRanger]

7Zip should have this feature.

If archiving to bluray or optical disc i recommend DVDisaster

I repair computers and nearly ALL of the common repairs that I have been doing have to do with HDD's. The one that I am focusing on currently overheated and the power supply box stopped giving it enough to run AND the Windows folder on the hard drive became corrupt. I brought the drive to my house to scan it with Easeus Data Recovery Pro and it found just about everything but the Windows folder was not completely fine. It scanned about 41 different versions of the folder and it's contents and I suppose that I CAN find the correct one to use but I have grabbed All the user files and they are all good. I want to use Multipar but the main operating system files do not use ".par". I WOULD like to delve deeper into this but I have reccomended a new desktop (elderly lady so she doesn't need a gaming computer. The first result on Amazon for $160 is a very old Core i5 with 16gb of memory and of course a terabyte hard drive but I have had the couple grab 2 1tb SSD's. I got the husband's computer transfered to the SSD And ran the windows 10 debloat. Smooth as butter on a hot skillet even though the rest of the computer is very old. I will be working on the Multipar from now on because I had no idea what could be done to save documents)

I also repair computers, but I would not recommend Multipar to non-tech savvy users. To the best of my knowledge, Multipar would have to be run every time a new file was created or an old file was changed. For example, if the user had a folder with family photos from five years ago, if you ran Multipar on the files in this folder, then this could be useful if you needed to recover them later. However, if the user created a new folder with family photos taken last Christmas, or they had an Excel spreadsheet that they updated with their current medication list, then Multipar would need to be run and these files selected. Concerning the Excel file, each time it was updated, Multipar would need to be run again and the Excel file selected again. For non-tech savvy users, the best data recovery plan is set-and-forget. I recommend IDrive cloud backup for my clients. The disadvantages of this are a yearly fee and privacy concerns. However, for privacy concerns, the backup can be encrypted with a secondary password that only the user knows; the disadvantage of this is that if the password is lost, then IDrive will not be able to help recover the data. However, the main advantages of IDrive are that the backup is scheduled to run each day automatically and that the backup is off-site.

@@Eternal_Tech I have Easeus file restore pro and it is pretty Bad A. The only real problem is having it scour and pull the file up 6 times in different lights and each picture is only a good Shard and then computer static. It depends on if the disk was fragmented before you recovered it lol. Old style HDD that are fragmented are a pain in the rump to recover files from. But hey! They can be recovered! If you have enough elbow grease lol

thanks man

[@ralphwiggum3134]

This thought just came to me: what if you used this on a Excel or Word document and then later used this to recover the file if it gets corrupted. Wouldn't you lose the changes you made since you created the .par2 files? Perhaps only use this on files that should never be changed and keep proper backups on your documents.

[@len9518]

??? You say it's not complex, but it is. I think a well maintained computer, can rely on the dism and scannow commands, to recover damage.

[@Eternal_Tech]

The dism and scannow commands only recover corrupt Windows system and driver files. These commands do not recover personal files, such as Microsoft Word documents, Excel spreadsheets, videos, and pictures.
