Restore Your Duplicati Docker Server Backups!

In this post we'll look at how to restore Docker application backups from Duplicati.
The process is actually pretty straightforward. In this video we'll be using Plex as our example.
I showed Plex up and running and playing media. Then I stopped the container and deleted the data from the server via SSH.
After showing that the server no longer worked, I retrieved a new Plex claim code and updated my Plex stack with it. I then re-deployed the container as a new, fresh application.
Once the container was up and running, I stopped it and then went over to Duplicati where I was able to go to my local backups and restore the application using all of the original file locations.
Make sure you also check the box that mentions file and folder permissions. We want to restore those permissions as well.
Once that process was complete, I restarted the Plex application in Portainer and went back to my Plex dashboard. The old server was still showing up, but we couldn't access anything. There was also a NEW server showing up that had all of my media ready to go just like it had been prior to me deleting the data.

Hey sir, I want to say you are a life saver, I was looking for something like this and you just give me a extremely well explained solution, thank you very much for this video, you just got a subscriber here!

[@DBTechYT]

Glad to hear that

[@omerbustun]

Thank you for these Docker videos.

[@DBTechYT]

Glad you like them!

Thank You from France, man, you're the best

[@ewfzappadis]

Have you done a video on how to backup synology's docker containers, in order to restore it on New SSD?

[@DBTechYT]

I have not

[@ewfzappadis]

@@DBTechYT ok thanks. Do you have somme tips? I have a DS716+ and soon i'm gonna change my two HDD's for 2 ssd's. I have already backed UP all of m'y datas and parameters, but i don't know how to transfer my docker to the ssd's...

[@DBTechYT]

SO you don't actually back up the containers. You back up the data in them. So, if you have the data in the containers backed up, then you're good to go. Swap out the drives, reinstall the containers. Then shut down the containers. Then replace the newly create data with the data you've got backed up. Then start the newly created containers with the "old" backed up data.

[@ewfzappadis]

@@DBTechYT ok. Thank you for the answer... I will test it as soon as i receive thé ssd's. You're thé best...

[@ICH42]

Cool Video, I was wondering do you have any experience with backing up & restoring data from a database, e.g. from a mariadb container and its volume?

[@lancecarter7054]

Thank you so much for the video and the previous one on how to set it up. I did have a question. My understanding is that you backup the files in "source" folder to "backup" folder on local drive. Then you backup the "backup" folder to cloud. Is there specific reason that we don't back up files directly to cloud? Also, for instance, let's say if my house burned down and all my local file got destroyed. Does this mean I need to first restore cloud backup to "backup" folder and then use the restored file in "backup" to restore local files? Like a pipeline

[@DBTechYT]

You absolutely could just back up straight to the cloud if you wanted. I like having multiple copies of my data, so I did a local backup and then a cloud backup.

[@robertarose2626]

Excellent video as always. How do you recommend backing up the actual data? In your example it would be the movie files for Plex...do you have a video for that? Would you suggest using Duplicati for this? Thanks!

[@DBTechYT]

It would be the same process. Just mount an additional folder for your media, but make sure your remote storage has enough space for things like movies and tv shows. I periodically just manually copy my media from my server to an 8tb external drive on a different system so I have local backups of everything in my media folders.

[@dubas1974]

Thanks. What if you lost your docker server and had to restore that? Would you just build the container structure again then do a restore for the container data like in this video? You only showed deleting the the data store but what if your container in portainer got nuked?

[@junny2233]

Im inspired now to do this but i have a question could i backup using this method then wiped the server to install OMV and then setup docker and restore the remotely backup? If that even possible

[@selfhosted]

Very cool! This seems too easy! I was using hyper backup on my nas but would be good to have a cloud option like drive. I may give this a go thanks!

[@DBTechYT]

Honestly I was having anxiety about this 2 part video series, but it turned out to work pretty well once I got my head wrapped around how it worked :)

[@selfhosted]

@@DBTechYT anxiety is a normal day for me. It’s been killing me lately. That’s why I’m not making videos. I have 0 energy because of high anxiety everyday.

[@DBTechYT]

@Geeked I sent you a DM on Discord

[@andrewpndavies]

HI - just posted on the previous Duplicati video - similar question though - can this work with Docker volumes and does it matter if it is a Bind mount or a Volume? Thanks -

[@DBTechYT]

I'm not sure if it matters. Definitely worth trying both methods and seeing.

[@jorgegomez374]

Great as always. Your point of view, have on a rpi4, nginx, duplicati,cloud flare dns,wordpress, synching,nextcloud, transmission. And what roads more containers like home assistant that right now is working on a separate pi. I have an old g5 mac pro Intel processors. Thinking of using it has a server for more applications that need the horse power which will you think I should move? Thank s

[@DBTechYT]

Great collection of apps you have there. The thing is that none of those apps really require much in the way of power. Some of the may use quite a bit of bandwidth, but the Pi4 has a 1Gb ethernet connection, so you won't get much improvement by moving to an older mac. If you decide to setup a media server, I would definitely consider the mac for that.

[@jorgegomez374]

@@DBTechYT thanks

[@vgamesx1]

That mac is a bit old so it's going to be fairly power hungry even doing nothing, so I wouldn't recommend using it regardless, if you decide you want an upgrade I advise using an old laptop, you can get them for around the cost of a rpi and even a very old sandy bridge or core 2 series shouldn't consume more than about 30W, you might even be able to find one for free if you look on Craigslist, a friend/family member may have kept one, as well as businesses throw out old computers all the time.

[@jorgegomez374]

@@vgamesx1 thanks

[@tomaszklimczak5706]

Great as always. One question how restore Duplicati container from scratch without Duplicati?

[@ltjojo5393]

Most likely, download the new Duplicati container, and overwrite the docker-compose.yml with the one from a backup.

[@betogamer08]

Do you know any way to backup a full windows system (all partitions) and deploy this image to multiple systems. I mean a kind of server client tool, hopefully with AD tools to auto join domain and tools like that?

[@idriskautsar757]

you save my live sir, thank you, but i have a question.. if the original server already corrupt, and duplicati run the backup job for that server, that's mean duplicati save the corrupt server ? if yes, how we can prevent that ?

[@girl-with-many-questions2659]

Regarding the latest (as of June 2022) Windows version of Duplicati. We can't find "full file backup", "incremental file backup", "differential file backup", "full image backup", "incremental image backup", and "differential image backup". (Some pretty simple, basic features that are available in MANY backup tools.) Are they not available in Duplicati? Or just very well hidden? We are looking for a replacement for our current UrBackUp server... and thought Duplicati would be a good choice... but it just seems like a huge "loss of functions" if we switch.

[@RameshKumar-rt8xb]

Is it possible to restore that backed up data to some other particular machine

[@myozone]

I guess for a total backup a clone (Proxmox) is the only way to go. Would the Duplicati way work for a total failure meaning everything gone on the docker/Portainer server and new install.

[@maxcharacterlimitreache-]

Thanks for the video but my question is: how will duplicati work if the os disk completely fails? I followed your first part of the duplicati installation but if my SSD with the operating system fails what can I do?

[@DBTechYT]

You should always have a backup. Then, when your OS drive fails, you reinstall your OS, Docker, Portainer, etc. Install your containers and then re-deploy your backup files over the newly installed containers.

[@maxcharacterlimitreache-]

@@DBTechYT ok so there is not a way of having an image of the complete os disk periodically saved? Like an .iso to etch in a new drive and pop in? I saw something about Clonezilla in the omv-extra menu but didn't understand it (I used Clonezilla once many years ago to switch from an hdd to sdd in a laptop)

I had duplicati installed but i didnt usw it becauase i didnt really know how till now. My question/issue now is if this will work with something like nextcloud that uses a mariadb. I would like to move my nextcloud to a new server but i havent figured out how yet.

[@DBTechYT]

You just have to make sure to map a directory in your Duplicati stack to where you store your databases

[@mattheww797]

@@DBTechYT Thanks for the tip. I will try this.

[@MarinJuracic]

Hi, great video. I've got one question. If I delete container and stack of plex can I just go to duplicati and restore plex backup. Will it recreate container back by itself wothout copying claim server code? Thanx

[@DBTechYT]

That's not how Duplicati works. You have to install the Application first and then restore your Duplicati data on top of it.

[@MarinJuracic]

@@DBTechYT Thanks DB, your tutorial for OMV projects are great, I mean the best out there, fast, brief and easy understanding. I built all containers plex, duckdns, qbittorrent.... with your help. Is there a way how to backup our containers and restore them if they break? If there is it could be your next tutorial😉. Keep up the good work, cheers!

[@MarinJuracic]

@@DBTechYT Just one more thing to check if I understood you correctly. So in following scenario I delete plex container. I rebuild it manually from scratch. After I go to duplicati and I restore my backup plex folder. Will I have plex running same as before without setting it up again?

[@DBTechYT]

"I rebuild it manually from scratch. After I go to duplicati and I restore my backup plex folder. Will I have plex running same as before without setting it up again?" ^^That's correct

[@MarinJuracic]

Hi DB once again. I have a situation here. I deleted plex container and tried to restore plex config folder with duplicati. It throws me an error 'warning while running backup Got 3119 warnings'. Did everything as you in video. Any idea what went wrong. Thanx

[@DBTechYT]

Did you run the Duplicati container with root privileges? (PUID=0 PGID=0)

[@MarinJuracic]

@@DBTechYT well when I made a stack I put zero value under PGID & PUID. I restored pi hole which was also inside config file with no issue but for some reason plex throws this error. Any suggestions? Sorry for bothering.

[@MarinJuracic]

@@DBTechYT hi David. Maybe if I delete whole Plex folder and then do restore with Duplicati, will that solve the problem of restoring files? Thanx

[@sammas3179]

why do you use the dev-disk-by-label folders in your /srv instead of creating a folder for every project/container

[@DBTechYT]

That's where I've decided to store my containers' config folders so that they're all in a central location. Each container gets its own sub-folder in there. For instance, here is the location of 3 of my containers' config folders: /srv/dev-disk-by-label-Files/Config/Chevereto /srv/dev-disk-by-label-Files/Config/PiHole /srv/dev-disk-by-label-Files/Config/QBittorrentVPN

[@sammas3179]

@@DBTechYT Thanks for the explanation. This video got me inspired for making backups of my own server. I now also use Duplicati to make backups and also use the srv folder. I do it as follows, every container has a subfolder in the srv folder where all their volumes are mounted, so not only the configs by also for instance the MySQL data is stored. This way I only have to add one (or maybe two for multiple backup locations) backups to duplicati with the entire srv folder.:)

[@MarinJuracic]

Hi to all. I'm able to restore every config file from various applications (duckdns, pihole..) except plex. It throws errors and unable to restore. I had 3 backup versions, tried each of them same thing happens. Thanx

[@DBTechYT]

Are you asking a question or making a statement? Either way it seems that there was something wrong with the way you backed up your Plex setup.

[@MarinJuracic]

@@DBTechYT sorry not making a statement, everything is working flawlessly except plex. I have no idea how could that particular folder be backed up in a wrong way cause I backed up complete config folder, where all the data of all containers are. Nevermind probably something went wrong I just wasn't sure if there was some solution to fix this that's why I was asking. Your tutorials are great!

[@ronald0122]

what if your complete omv server/computer crashed?

[@DBTechYT]

Then you install the apps and then restore the backup data over the install data like I show in this video.

[@ronald0122]

@@DBTechYT this still works if the version of the docker container differs?

[@KronosaurusRex]

Let’s say you start with a fresh install, how do you recover your duplicati container to then recover everything else?

[@DBTechYT]

You just install duplicati and connect wherever your backups are and then restore that. There's also an option to backup and restore your duplicati settings for this kind of thing

[@KronosaurusRex]

Oh didn’t think it was that easy. Thanks for your time, and as always great vid. I’ve set my docker thanks to you almost on exclusive.

[@streambarhoum4464]

How to that using rsync with crontab And docker-compose? Without the need of omv and duplicati. (just In a professional way 😉) 😊✨🤩 could you please do video on that?

[@PtR-ec1wz]

Might want to make a note when your docket dies with duplicati on it. You’d have to restore duplicati somehow first.

[@DBTechYT]

You would reinstall your docker setup including ALL of your containers (and duplicati) and then import your backed up data to get back to where you were. That's how Duplicati works.

[@NovaCayn]

Hard to follow when I am not using docker on my OMV. My docker is on my Debian 11 server and my OMV (backup solution) is on a different area of my network. If I had everything in one location like you have then I would be fine. Good tutorial but not helpful for me.
