Come and join us at Synology Community. Was looking at a really cheap 120j, which doesn't support Btrfs. I have seen that using BTRFS from even this thread that all it really offers is checksumming and some snapshoting ability unless Synology wrote in the bitrot protection elsewhere. This removes the chance of bitrot being undetected when loading a file, making changes and then saving the file with the corruption still in place, except now undetectable as the parity is updated. I want to ensure I am 3 2 1 compliant as well as protect against bitrot. Ask a question or start a discussion now. While bit-rot isn't the most common thing, it occurs and is often attributed with items that haven't been read recently. TrueNAS is great if you want to tinker and roll out your own powerful hardware. This allows the NAS to auto-repair detected bitrot errors. RAID scrubbing? Bitrot is commonly considered to be where long term stored media, usually magnetic, undergoes the occasional tiny random magnetic alteration which results in data becoming altered or corrupted, despite that data never having been read, written or even accessed. I've been managing Synology devices for last 10-11 years and never had issues. I restored it using hyper backup, which nicely restored all of my shares and most of the stuff that synology officially supported for this model. Fortunately, the Synology Data Scrub Aug 19, 2021 · Synology does BOTH, depending on where you look at. If you use 3-2-1 backup strategy, you should be fine. run chkbit before each backup. I admit though, I am very hopeful for BTRFS implementation (it's better than ZFS). Worry about it in drives that start to get 4-5 years old. Nov 17, 2021 · I have wanted to transfer the data from ext4 to btrfs for the better reliance against bitrot. So here's my Rube Goldberg plan Create a new shared folder with checksum protection enabled. When I created the shared folder which holds my Docker image configs, I apparently missed enabling checksum protection (I'm not sure why this isn't a default for btrfs volumes but nonetheless). check for bitrot on the backup media. However now I'm at a place where I also wanted to enable bitrot protection to at least some of my shares. You need raid to repair bitrot, as synology has written a module that uses Btrfs to detect errors and MDRAID parity to repair it. Jul 20, 2019 · When bitrot happens on a one or two bay nas, you need te recover the file from backup. Bitrot is detected and repaired on access and during a file system scrub. Dec 31, 2022 · The issue is that every error, even checksum errors are now called bitrot, while it can be caused by many hard disk failures. Encryption is also built into the solution. There is no bitrot protection on ext4. May 25, 2023 · Synology Knowledge Center offers comprehensive support, providing answers to frequently asked questions, troubleshooting steps, software tutorials, and all the technical documentation you may need.

Dec 10, 2023 · Based on the diagram below, Synology has implemented the layers in between the file systems and disks to ensure that Synology has full control to achieve the highest stability. To mitigate is, you must start with good backups. You should. Drives were consumer models across a mix of all brands. With Hyperbackup you can periodically check the integrity of the backup. Stop Docker. So, I suggest checking what exactly the old NAS did store, testing what exactly Synology stores and than coming to some conclusions. I know RAID isn't a replacement for backup. How common is Bitrot? Bitrot is rare. expanded, shrunk, broke and degraded them, and tried to get the RAID5 bug to rear it's head) a lot with btrfs pools before getting a Synology NAS. Which Synology NAS models support the Btrfs file system? And don't worry about bitrot. I understand that the ZFS and BTRFS file system which, along with periodic "scrubbing" will take snapshots of the data and then be able to correct or identify whether a file has been corrupted and perform a recovery, like with parity files. backup regularly. I have a shared folder for which "du -h" prints around 850 GiB of size, while Synology prints ~560 GiB at multiple places in its own web-UI. Disk redundacy via RAID. Does the DS 220j have any protection against bitrot? Nope. Really old drives may have error rates that exceed ECC, though, due to signal logs from magnetic entropy. Dec 5, 2014 · chkbit is a lightweight bitrot detection tool (OS X/Linux/Windows). chkbit cannot repair bitrot, its job is simply to detect it. What is Btrfs? Btrfs is a modern file system developed by multiple parties and now supported by select Synology NAS models. But if you want stability without a hassle, use Synology. The Btrfs file system on Synology also offers the benefits of Btrfs RAID, including automatic corruption detection and correction. After 7 years, I ran an MD5 check on both sets of data. Consider upgrading to a newer NAS that supports BTRFS, which (assuming you use SHR 1 or better) all but eliminates this risk. Dec 31, 2022 · All RAM was non-ECC. The term is useless in my world Error code correction is built into modern storage media (like HDD and SSD) which should keep you safe from bitrot. So while it may not be able to correct errors, it can detect bitrot; and Synology has the smarts to identify the failed underlying sectors. And if it does, it's most likely that it affects negligible parts of the file (ie, corruption in a frame of video). Nov 8, 2024 · You also have access to things like erasure coding, data protection , bitrot detection and data integrity services. in case of bitrot restore from a checked backup.

I have installed another disk, with a different volume to do a back up. Since raid is not a backup and 100% uptime is not a priority I'll forgo raid 1 and have the following setup: 1 hdd in NAS, 1 attached to my main pc in the same location The next-generation Btrfs file system brings these tools to Synology NAS servers, allowing businesses and organizations to reduce maintenance overhead and efficiently store their data. I recently moved over from ext4 to btrfs on my DS416Play (4GB, DSM7). I read the instructions online and it says remove the volume, and then reformat the disk into btrfs and re-initiate volume. For full bitrot protection you will need three things: Those two allow the NAS to detect bitrot errors. What would be the best method of protecting this off-site backup from Bitrot? Would I need to wipe the drive and re-do the backup periodically? Run Extended SMART? Still don't understand why Synology quite heavy markets btrfs bitrot protection but fails to enable it by default when making the share folders (makes it no better then using ext4, apart from snapshots use and metadata is still Checksumed) especially when using mirrors (raid10/1) because you have to "trust" both drives have same data when In terms of Synology - they are standard for small and mid-size companies. The next-generation Btrfs file system brings these tools to Synology NAS servers, allowing businesses and organizations to reduce maintenance overhead and efficiently store their data. A place to answer all your Synology questions. According to the BTRFS research I've done, all the bitrot protection is done by the BTRFS Raid level and Synology doesn't employ that implementation.
