I searched for many videos to better understand Snapshot replication between two Synology devices, and now I have found the right one. It's well explained; keep it up!
Unfortunately, you can't use the CPU usage in this video because I am running DSM virtually and it only has one CPU core assigned. The performance will be significantly better if it's running natively on the device!
@@WunderTechTutorials That's what I thought. Since I already have all files duplicated, I just tried to start a Replication, then immediately stop it and copy over the files to speed up the initial replication. Unfortunately, the replicated folder is "secured" and I can't copy the files over no matter what I try, any idea how to get around that, or if that even works?
@@leopoldmaximilian3764 I don't think that you can unfortunately. Your best bet is to probably just run it and wait (even though it will take a while).
Thanks for this video. I am just wondering, if the source NAS suddenly dies, you have now the destination NAS left with a "read only" folder. How would you make it a read and write folder.
@@dzmelinux7769 I'm not sure, I haven't ever tried or been in that situation. My guess is you can do a switch or failover. Definitely a question for Synology if it's business-critical.
This happened to me. One of the drives just died suddenly and was left with a second read-only drive. I got an external hard drive enclosure, copied all folders (took 2 days). Then moved the files via usb. restored on a new drive.
Hi thanks for the video. @2:03 you said allow the DSM and Shared Folder ports in the firewall. Did you mean to say the Shared Snapshot Replication port?
Yes, the screen should say "shared folders & Advanced LUNs" and it will display port 5566 (as long as you didn't change it). That's the port that will need to be opened, as well as the DSM port.
@@WunderTechTutorials Still struggeling to get my two machines to connect. Does Port DSM port and 5566 need to opened at Router level for BOTH machines? Would love to get this working. Hyperbackup Vault works perfectly. Many thanks
@@StevenWilliamsHome That is correct, both will need to be opened on both sides. You can then use Synology's firewall to limit connections to only the other devices, if you'd like.
Uptime. If you need close to 100% uptime, Snapshot Replication is the best option between the two. If you can be down for an extended period of time, HB is the way to go in my opinion.
i know when using replication locally you said it doesnt take much space, but when going to a second nas wouldnt it be a complete second copy of all the data to protect against ransomware or deletion of the entire folder? I honestly have a massive task of backing up 100s of TB on multiple NASs and dont even know where to start as there is no "synology supported" backup currently and I am trying to be as cost effective as possible, would love to be able to message you somewhere like on discord/telegram or something, so hard to have a back an forth on here without giving too much information.
I'd love to help but that's out of my league. I work with smaller subsets of data - if you need to back up that much, you really should contact Synology directly and try and figure out the best way to handle that.
@@WunderTechTutorials I have tried that, I’m afraid they don’t take cost into account when advising. Don’t let me bother you, there are just some things you can’t test without affecting the live environment, for example, for the biggest shares on the main nas there are shares on secondary nas with the exact same name and file but on multiple volumes, I’m afraid to even let shared folder sync take over management of that because you cant clearly specify destination share location or volume… hyperbackup hates the fact that both my source and destination are encrypted shares and corrupted due to file name lengthening due to encryption… and complete system backup only lets you select 1 volume destination so if backing up a nas with a few volumes close to 108Tb limit how is it meant to fit all that in 1 volume… and it’s all way too big for cloud or backblaze etc… I just don’t think I will ever get a backup solution from synology working safely
I have two Synology NAS's running BTRFS in two locations. Presently I have them Syncing using ShareSync and each device backs up to the other every other day using HyperBackup. I am not presently using Snapshot replication. In my setup, given the two different locations, would I be better off setting up Snapshot Replication locally on each device or across to the opposite device?
If you don't have a real need to be able to failover to another device and just want to ensure the data is backed up on both devices, I think that Hyper Backup is perfect!
@@WunderTechTutorials I'd love to be able to failover to the other device automatically, but I haven't figured that out yet. I use NoteStation on one of the devices and it's backed up to the other, but a COMPLETE failover--all services, would be the most desired scenario.
I'm not entirely sure why they would be greyed out, but I have never used Snapshot Replication locally. I have only used it with the remote option and a second Synology NAS so the process could be different.
Do you know if theres a way to change the destination share name when replicating snapshots? If you replicate the homes share, it automatically changes it to homes-replicated on destination, so it seems like its supported under the hood at least
managed to figure it out. You can just rename the share on destination nas, and snapshot replication automatically knows the new name. I'm pretty impressed with how slick DS7 is
Thanks for the tutorial. Can you restore all applications with data settings and accounts say wordpress etc into "new" Synology like ghost image restore that do not need tweaks/troubleshooting after restore job. If this application cannot do that so far, what other tool can do that complete system snapshot backup/restore with apps into other/new device, Thanks again and cheers

Perfect, that can save my life one day!!!
Glad it helped, thanks for watching!
Another great video. Thanks for the walk thru
Thanks for watching!
its a helpful note, thank you!
The CPU usage shoot up to 92% at the 4:42 mark.
Is Snapshot Replication always this CPU intensive when the Snapshot Replication runs?
Unfortunately, you can't use the CPU usage in this video because I am running DSM virtually and it only has one CPU core assigned. The performance will be significantly better if it's running natively on the device!
Thanks you to save my time
VERY PERFECT AND HELPFUL THANK YOU!
Brill stuff as always thanks
Thanks so much for the support!
Thank you. However, can you please recreate this video with a powerpoint and rename the NASs to something less confusing like NAS-NY and NAS-SF.
Great Video, thank you! Can I replace "shared folder sync" with this option, or is there still a use case where shared folder sync has the upper hand?
They are similar, but this is "better" as it incorporates snapshots.

I haven't been in that exact scenario so I can't say for sure, but I imagine you'd do a switch or failover and it'll become the read/write version.
@@WunderTechTutorials so, you can do a fail-over on the destination NAS without the source NAS?
@@dzmelinux7769 I'm not sure, I haven't ever tried or been in that situation. My guess is you can do a switch or failover.

do you also open ports of both machines routers too?

Thanks for the great video. How to setup Replication to a remote NAS that in different network?
The process is the same, but you'll have to connect to it somehow (either by port forwarding or VPN).
@@WunderTechTutorialsthanks!
Which backup solution save cpu resources? Hyper backup, Snapshots? I still confusing to use best backup save power and resources
I honestly haven't ever measured CPU resources. I imagine that they will be similar, but that's just an educated guess.
So, at what scenario would you prefer snapshot replication vs Hyperbackup?
Uptime. If you need close to 100% uptime, Snapshot Replication is the best option between the two. If you can be down for an extended period of time, HB is the way to go in my opinion.
@@WunderTechTutorials Thanks, I just read that the home folder has even more regulations if you use replication.

This is really just to sync one Synology folder from one NAS to another. I unfortunately don't think it will do what you're looking for.
