Synology BTRFS Snapshot Replication to Rapidly Failover for Crucial Applications

Рет қаралды 10,439

Күн бұрын

Synology BTRFS Snapshot Replication allows you to send BTRFS snapshots from one Synology NAS to another, at ultra low intervals. Then should the main unit fail a secondary unit can be failed over to get back up and running! This is crucial for mission critical applications which cannot have down time. These snapshots are also ultra thin which reduces unnecessary bandwidth!

Great video, since I am not sure how to backup my docker container or clone them to another synology. I might use the video to create a save point for my synology

a small question, which is better for outsite backup? Hyper backup or snapshot replication? and what's different?

@leopoldmaximilian3764 2 жыл бұрын

Interesting video! I currently use "shared folder sync" to keep two remote Synologys at the same state, is Snapshot Replication a superior version of that pretty much?

Hi Will, looking for the link to the Open VPN mentioned @ 4:43 to 5:00 min, not sure if you added the link to description. Thanks again!

Hi There, please can you make a video on how to convert the file system from EXT4 to BTRFS on a 2 bay NAS, speifically DS218 Play. I have got just over 600Gb of data on it and I can't find a much info on the net that fills me with confidence in trying it out myself. many thanks

@ryanyu5051 2 жыл бұрын

Appreciate your great info! Can I set up Synology Drive ShareSync with a remote Synology NAS, then set up BTRFS Replication in the remote NAS? In that way, both NAS can be sync with both read and write actions, and both have replications setup.

@SpaceRexWill 2 жыл бұрын

You can do this, however it will not be as bullet proof as this. For example if drive failed to sync a file for some reason it would not be backed up. However for a non mission critical setup its totally fine!

Please HELP! I JUST BOUGHT A SYNOLOGY DS220J WITH TWO 4T DRIVES THAT I WANT TO USE RAID1, OR SHR BASICALLY. THE SYNOLOGY SEEMED TO HAVE MADE a storage pool and volume FOR ME AUTOMATICALLY in set up screen,oops caps sorry, but it made the SHR using ext4, which all of the vids I've seen said to use btrfs. Now that I see this bug happened....should I keep it as synology made it, can I not have btrfs ever now....or can I delete the pool and or volume and do it again manually and choose btrfs. I am STUCK at this point, I don't want to go forward without knowing! Thanks so much in advance

What rights should be granted to the snapshot user? Does it have to be admin?

@kutzencop 3 жыл бұрын

When you set up the Replication to a different Synology NAS, does the account you specify on the "target" NAS need to be an admin account? Or can it be just a regular user account? If the latter, is there any special access required for that user account regarding files and/or applications?

It will have to be an admin

I want to have an exact NAS clone at two separate locations. I have to work from both of those and want to take advantage of the local LAN speed versus pulling large files across internet. Any change I make in one location I want replicated to the other bi-directionally. I control the router/firewall in one location but not the other though I could ask to open a port. How would I do this?

Ah then you want synology drive share sync. Video comes out in about a week, open for members now

I've successfully setup replication on my two nas' (DS920 -> DS418) Works great. Currently, both shares are compressed. My question is, can I set my production share to uncompressed, leaving the target compressed? Since i do 4k video, I need a quick read time.

@SpaceRexWill Жыл бұрын

I don't think so. BTRFS is likely sending the data compressed in the snapshot form. If you are video editing compression likely will do nothing and probably worth it to disable

hi spacerex, i had 1 problem that i'm facing, is that the "Snapshot Replication" doesn't replicate the latest ACL (Access Control List). Example = Folder "A" has 1 user with read-only access, but i recently added a new user with write access in the SOURCE nas, but after the replication task completes, i only see 1 user with the read-only access instead of 2 users) in my DESTINATION nas. How can i fix this?

You have to have your user auth on something like an LDAP server to do this

Hello, can you please give an information about disk quotas in btrfs system in Synology? In the filesystem is btrfs, is it possible in synology to use group and user quoatas or not anymore?

@SpaceRexWill 2 жыл бұрын

So I don’t think you can do quotas with a BTRFS send, but you can use quotas everywhere else

@homeandr1 2 жыл бұрын

@@SpaceRexWill Thank you for your answer, can you check please in your Synology, how the quotas working with btrfs. I mean quotas for users and groups. I mean if the filesystem is btrfs then quotas for users and groups are unavailable?
