Downloaded backup size is much larger than content size.

[niemyjski]

The problem

I noticed when downloading a snapshot (created via snapshot service) via edge latest on Windows 11 that the file size is much larger than the content size. I'm not sure what could be causing this but it could be something to do with the streaming

Are you sure, that the downloaded file is ~45GB 🤔

[niemyjski]

Yes

[mib1185]

Please try the backup_full service, since snapshot_full is depreciated

Hey there @home-assistant/supervisor, mind taking a look at this issue as it has been labeled with an integration (hassio) you are listed as a code owner for? Thanks!

This sounds like a bug in Windows, or even 7zip.
What the Supervisor report is what's correct.

[mib1185]

direct downloaded via supervisor UI (created by backup_full service) :
size compared between supervisor and windows and 7zip ✔️

[niemyjski]

I'm running a hassio.backup_full backup now and it takes forever so I'll follow up when that is done. I was using the hacs addon due to auto purge, it's a proxy and calls the backup apis (confirmed from looking at the source). My apologies, I had the terminology wrong... I knew it was either backups or snapshots and one was deprecated.

[niemyjski]

I'll have to check it in the morning the backup is taking way too long on a beast of a machine with only NVME storage..

21-10-25 21:12:34 INFO (MainThread) [supervisor.addons.addon] Finish backup for addon a0d7b954_influxdb
```

[niemyjski]

Definitely a bug of some kind here. I ran one full backup using the service call at 8:20pm:

And then a daily at midnight using the same service call:

[niemyjski]

The default service call says it will have a date based file name, but when It's created it doesn't seem like it and the downloaded file is called tar, this probably should be it's own issue.

Regardless, there seems to be some differences between the backup api that that addon is calling and this service call.

tar is the backup from 8:20pm

tar(1) is the backup from midnight

One has a media compressed tar and the other doesn't (at least with content), Not sure why both don't have it but seems like part of the core issue. Perhaps it's being removed (bug?) but the compressed file isn't shrunk?

[mib1185]

could you please share the corresponding logs from supervisor for both backup jobs?

[niemyjski]

Is there a good way to view the supervisor logs? They seem truncated and I can only see the logs for the last 3 hours (no restarts have happened).

Still an issue with latest version

[agners]

@niemyjski logs of the two backup types (via addon and directly calling the service) should be helpful here.

You can get older Supervisor logs using journalctl on the OS shell. To get access to the OS shell, you have to follow this guide.

You then can get logs using:

journalctl -t hassos-supervisor

[niemyjski]

I'm no longer calling that addon. Is there any way to get these logs without enabling ssh and rebooting the server? I have a lot of services running on this that I'd prefer not to roll the whole box multiple times. Can this be exposed as part of the supervisor logs or maybe a feature to download a support zip that contains this and other logs?

Here are the logs from the supervisor ui

I noticed if I don't back up the media folder, influx, maria, or compre addons the size of the backup is 843mb. I don't think doing a partial backup would cause the smaller size.. I'm going to try creating a backup of each of the above separately to see if I can narrow it down.

The Exadel CompreFace addon was 2gb to backup and it should be really small. Working on the others

[agners]

The Supervisor log is available from the frontend too, however, it only shows the last 100 lines or so. You have been asking for older logs, currently the only way to get to older logs is through the console.

[niemyjski]

Can we make this configurable?

I have the same problem. The backup size increases by gigabytes every month. Now I remembered that I have Transmission installed for downloading Torrent files. And the additional disk is mounted to the folder where the Home Assistant files are located (/share/, /usr/share/hassio/share/).
It turns out that this folder is included in the backup.
It looks like you need to unmount this disk before making a backup.
I would like to automate this...

[Bagunda]

I confirm. After unmounting the disk, the backup became normal size.
