backup completes but uploads to nextcloud with 0 bytes about hassio-nextcloud-backup

[hannemann]

#22 I had success when i tried to switch to another lib than request (https://github.com/sindresorhus/got)

The got lib works quite similar to request hence i recommend to use it in hassioApiTools aswell

[Sebclem]

I have seen this on my today backup, I already find the problems, I will make the fix realise tonight, thank for the issue !

[Raoulex]

Thank you also for this awesome add-on, great work

[Sebclem]

I fix it with the 0.7.3 release, i close the issue but if you still have the bug, fell free to open a new one.

[Raoulex]

Unfortunately, issue remains, just no error in the log, but the file size is still 0

[Sebclem]

Hum, ok interesting, i can't reproduce this issue, is this with manual backup or auto ?

[Sebclem]

Ok, i will add more verbose logs to find where is the issue...
Can i have some informations about your setup:

• Home assistant version
• HassIo version
• System arch
• Nextcloud version

[Raoulex]

Home Assistant version: 0.106.4
Supervisor version: 206
Nextcloud version : 18.0.1

it still updates with size 0

[sam-harry]

Thank you for your hard work on this add-on!

I'm experiencing the same issue (manual backup uploads a size 0 file). My system setup is:

[Raoulex]

Adding 'overwriteprotocol' => 'https' in config didn't solved the issue, in my opinion is something from the ssl

[Sebclem]

I'm more interesting by this =>skipped - file is outside of specified music folder
I think it's more an issue with the destination folder.
This afternoon i will add the option to change le upload location.

I found this thread on google but i think it's no very useful here.

And just to be sure, did you use app password ? If yes, can you try with your usual password ?

[Raoulex]

I usually use app password, but today i changed to usual password and still the same.

I don't really think is from the music error, it does not come all the time,
*listeners":{"...":"Over 20 items, aborting normalization"}
this is more likely the problem, i see that there where problems from v 17 of nextcloud, but who knows

[sebortner]

Just to bump this thread. I'm experiencing similar issues. Neither manual, nor automatic backups have proper sizes.

Raspberry 3B+
Home Assistant 0.111.1
Supervisor 227
NC Addon 0.7.5
Nextcloud 18.0.4

Thanks for your work Sebclem!

[kicker334]

Just another bump on this thread as well. I have similar issue with both manual and automatic backups. I use app password and it worked when I first installed the add-on... It doesn't seem to be working anymore.

Raspberry Pi
Home Assistant 0.112.1
Supervisor 228
NC Addon 0.7.8
Nextcloud 19.0.0

[Sebclem]

@sebortner @kicker334
Can i have the addon and nextcloud logs ? (In pastbin or other)

I'm a bit stuck with this issue because i can't reproduce it...

I will try to install another nextcloud in a VM.

[kicker334]

I'm seeing 0 byte uploads for both manual and automatic backups as well. I am using Amazon S3 as my Nextcloud storage back-end in case it makes any difference. Nextcloud version is 19.0.0, but I was experiencing this issue with Nextcloud 18 as well.

Please let me know how I can further help debug this issue.

Here's the add-on log:

Here's Nextcloud's log. There are no errors when the backup job finishes. I see the following errors when I navigate to the backup directory via the web interface. I suspect that they are triggered because the files are 0 bytes long.

[Sebclem]

Hello everyone,

Can i have your installation method for your Nextcloud instance ? (Apache, Lighthttpd, Snap package, docker etc...)
I still trying to reproduce this issue.

[sebortner]

I actually have it installed in a datacenter where it has been pre configured for me. https://www.hetzner.de/storage/storage-share I don't really have any more info on how the instance is installed within their environment.

I use a docker setup from the examples suggested by the Nextcloud team. Here's the specific docker config I use. It features an nginx proxy with letsencrypt-companion to handle certs, behind which Nextcloud runs on another nginx instance, and postgresql as the database back-end.

[kicker334]

I use the snap install on a ubuntu server OS.

[kicker334]

I recently got this error:

And also I saw this in the logs at the beginning. Not sure if it is important or not.

[kicker334]

@Sebclem is there anything else we can do to help with this issue?

[Sebclem]

At this point, I just need time to install a new nextcloud instance. With a bit of luck, I will be able to reproduce this issue.

I'm also considering splitting the backups file to prevent errors related to max body size and this can maybe also fix this issue.

[kicker334]

I attempted to send a pull request. sometimes :'s are a problem with filenames. I figured it was worth a shot. I'm not a github expert, so I probably did it wrong, but you should see the pull requests and make the change in a few minutes.

[mojo17]

Unfortunately, this patch did not resolve the issue for me. I'm still getting 0 byte files in Nextcloud. Log files do not show any errors.

[kicker334]

It was worth a shot. I'm not a javascript person... I'll keep digging a little later

[kicker334]

Here's what I got... As I said, I'm not a JS person. My guess is that it has something to do with line 169 let req = request.put(option)
I'm having difficulty finding the implementation method elsewhere on the internet for how this was done. That doesn't mean it is incorrect, I just can't find it. There's a webdav client in nodeJS that could be used that has putfilecontents. Perhaps that can be used instead of the .put? https://github.com/perry-mitchell/webdav-client#putfilecontents and NextCloud seems to think it is a good package (as of 2017)? https://nextcloud.com/blog/using-webdav-fs-to-access-files-in-nextcloud/.
I see some reference to having method: 'PUT', in the options tag as well. Maybe that is required?
I'm not sure how to include the latest version of webdav in this project to possibly use putfilecontents.

[Sebclem]

I have made a new release, let me know is this fix your issue. If yes, i will move all my request to Got.

[hannemann]

After refreshing the addon store the update became available and a manual backup succeeded.

[Raoulex]

Problem solved, i can confirm, tried manual and auto backup, everything works.
PS: need to use app password, it didn't work with user password
Can be closed

[kicker334]

I can confirm as well. Thank you @hannemann!
