Setting Up a 3-2-1 Backup for Synology NAS

Рет қаралды 27,918

Күн бұрын

This video goes over how to setup a 3-2-1 backup solution for an office file server on Synology NAS. This uses snapshot replication to sync files from one onsite NAS to another, then uses hyper-backup to backup the data offsite. This is crucial for making sure that your data stays backed up and accessible, no matter what happens.

Speaking as an IT professional who has worked many years in the disciplines of disaster recovery and business continuity planning, I can tell you that the conversation needs only to be re-focused from “How much will this cost me?” TO “How much will it cost me if I lose my data?” … and that usually gets 3-2-1 easily justifiable :)

Thanks for this brief explaination, when I ever start a business I will use this technique, for now for me as a Synology user where I store all my personnell files from the computer to the NAS, the NAS is allready the secondary to my home PC. I keep an off site copy of all my data (which I redo every six months) at my parents house. I plan on saving my most important files as well to a cloud service, but haven't looked into that one.

Great and helpful video. I understand raid is not a backup, I’m having trouble finding an answer for best practice if the offsite backup NAS configuration should be a RAID / SHR or to use the entire available storage for backup?

Super useful video and great advice. You should do a restore from off-site HyperBackup from C2 video.... help us understand the other side and often the task most done while sweating!!!

What's the solution and issues with Replication of the homes folder? I see when you try and create replication it warns about the homes folder not being able to perform a switchover or failover. In your video the folder was renamed. How can this all be made to work, as users will be using Synology Drive??

In another video you showed using the Synology rack system and doing snapshot with that. What is a better solution. Two nas or 1 rack system?

Hi incredibly useful information. I'm trying to figure out best practices for retention since there are retention settings EVERYWHERE! I have retention settings for ActiveBackup for business PC/Mac to primary server. Then I have retention settings for local snapshots. There are retention settings for local DR server. There are retention settings for Hyper Backup remote server. It's all very convoluted in the context of a 3-2-1 backup strategy.

I have a question regarding the settings related to some synology applications like Drive, Photos etc. Is there a way to copy them to secondary nas using snapshot replication?

@Somebody.42 7 ай бұрын

No, snapshot replication does not backup applications but you can do it with Hyper Backup. There is one specific down side for Drive and Photos, if you want to restore the app you must restore the folder too. And it can take a lot of time for these two since there is a lot of little files. I suggest not to turn on data compression for that btw, it slow down the restore a lot.

How about Synology High Availability? If there are going to be two NAS locally, would that be a viable option to use High Availability instead of Snapshot Replication? Any cons?

I think,yes. But you must use two identical NAS.

ABB Client vs Hyperbackup to the backup NAS? I know the video is showing HB, I'm just starting that segment so you may have answered it in there already

@KaceyGreen 10 ай бұрын

I currently have the ABB Client since I have 3 NASs but I think one advantage is HB will let me send stuff to an expansion unit without spanning the volume if there are space constraints on the backup server, 3rd server really doesn't have much in common with main, it runs a few VMs and has some small file shares on it, all are on the latest DSM

Hi Spacerex, currently i have a 2 bay (723+) with 2 8tb drives(SHR) on EXT4. Is it a good option to change to a Btrfs system by bying a 4 bay (923+) and 1 new 8tb drive, install that in the 923+ with btrfs as single drive. Then copy all data from the 723+ to the 923+. When finished format the 2 8tb drives of the 723+ and add them to the 923+? I searched your whole account for something that would advice in this but cant find it. And whats the best option to transfer all the data. Thank you so much

@sebastianschneider4345 10 ай бұрын

Interesting scenario! Btrfs is supreme in many aspects. So yeah, if it's in your budget, that's a good solution. For the HOW TO DO THE 17:23 TRANSFER, as always, there are multiple options. First: yes SHR raid is possible with only one disk. So your way is plausible. synology drive is the way. It not only can sync "NAS to client" but also "NAS to NAS". And that's by far the easiest way to guarantee, that all files will be 100% identical. Or you can mount individual folders via NFS and then copy from them (more complicated and for your project not really better). Or you export your data via hyper backup and recover it on you secondary. But that'll be dumb: Takes MUCH more time (create = move backup + restore backup), and also you'd need double the space on your target Nas, because backup + recovered data needs space. Do you also have to move settings, users and privileges, then maybe backup your DSM settings, or use the migration tool. Both I've never tried before. So I can't say anything to both.

Hi! Great video! I've bought my first Synology a few months ago, after watching your videos! Can I please ask you a question? Thanks A) I think that some of my data are decently safe, stored in three locations: 1) my Mac ssd + 2) apple iCloud + 3) Synology backup through Time Machine B) I'm not sure about other data. I store other data in two locations: 1) Synology + 2) hyper backup from Synology to C2 Storage. My question regards this data sub b). If my Synology gets corrupted (hacker attack, data corruption, etc), will I be able to restore the data from C2 Storage or the corruption will affect both my Synology and C2 hyper backups? In other words: how much is hyper backup on C2 storage safe? Is Hyper Backup + C2 storage a valid solution in order to restore corrupted data or the corruption of my Synology will transfer to C2 storage? Thank you very much! Great video!

@Manu-hi8ff 9 ай бұрын

Super nice Video. But what i dont get is the timing. Wouldn't it make sense, especially with regard to ransomware, to make the different backups in different cycles? E.g. Primary Nas hourly with snapshot, daily backup with hyperbackup to an external Nas and a weekly backup e.g. to an external hard disk or C2? Further it would be also possible, with your large NAS a Snapshop hourly internally on another volume and only daily a backup on the Primary NAS. So the primary would be the rest of the day from the network and so safe from ransomware?

@SpaceRexWill 9 ай бұрын

So both hyperbackup and snapshot replication have multiple versions associated with them, so you don't have to worry about the encrypted files overwriting your backup. You will have as many days as you set in your retention settings to recover any files and realize the ransomware has occurred

Snapshot replication does this easily. You just hit “reprotect” and it will send the snapshots from NAS2 (currently primary) to NAS1. You could then switch back over to NAS1 by doing a switch over

I think i need some clarification, are the configurationfile (usercredentials, VPN setup etc.) also synced in the snapshot? Otherwise, your actions at 26:21 where you choose "Fail Over" as action on your secondary will not work untill your usercredentials are up and running on the secondary? I am just a bit confused as i think you spoke about not syncing the configurationfile in the beginning of the video. Otherwise, great stuff!

@SpaceRexWill 7 ай бұрын

So for something like a VPN you would need a backup VPN option. This is really setup best for a LAN office file server. VPN and stuff you generally have to fail over on your own

@@SpaceRexWill you mention LDAP or domainserver for syncing usercredentials and settings to the secondary. So basicly, can you confirm that usercredentials and user privileges are not synched to the secondary in you videoexample (Without LDAP or domainserver). If yes, I woder why this is, as hyberbackup are able to do a full system backup including everything.

Users and permissions will be synced over with LDAP, but packages like VPN will not be. Hyperbackup (even just the package version) will be able to restore, but just not instantly

Why not use Snapshot replication for the third NAS instead of Hyperbackup ? Is there a reason not to use it ?

@SpaceRexWill 9 ай бұрын

For very complex file systems that are changing rapidly I will sometimes use snapshot as the offsite, but I tend to try to avoid it. Part of the reason is to hedge your bets. I would prefer to have 2 different ways I am backing up the primary data set, rather than 1. So if one day snapshot replication fails silently, then hopefully hyperbackup does not

I'm having trouble with the Hyperbackup. I'm using now a 4tb usb seagate (no power suply) and the backup go until 99% and never finish. I tried to cancel , Restart the NAs. When I used a 2tb seagate with power suply I never had a trouble like this. But 2tb is not enough to my files now.
