Unable to create snapshot

Nico · November 6, 2018, 7:03pm

Hi, since a few weeks my snapshot function is no longer working.
When I try t do a manual snapshot nothing happens even after some hours, I’m running on 0.81.6 in docker on a NUC and everything else works flawlessly.
From the hassio’s system tab I can view that the snapshot process begins but never ends, my last snapshot was done a few weeks ago and worked without problems.

The snapshot button is not grayed but if I press it the system tells me that the last snapshot is still running.

18-11-06 18:50:37 ERROR (MainThread) [hassio.snapshots] A snapshot/restore process is already running
18-11-06 18:52:31 INFO (MainThread) [hassio.snapshots] Found 2 snapshot files

Even browsing to the backup location shows nothing so is not a problem of the GUI not refreshing.

Thanks

Did you find a solution? I’ve got the same problem now (hass.io 0.90.0). Thnx

Hey @Mark_Schuurmans .

I don’t get it. I am getting now the same issue… The only way for me to work is to save something under the /config/www folder, could be as well /config/www/tmp (if I created the folder).

Everytime I try somewhere else like /tmp it does not work. Knowing of course I have in my config:

homeassistant:
  whitelist_external_dirs: 
    - /tmp

I actually found out that the problem was the folder mounted in hassio/shares with movies for plex to work. When the snapshot system tried to back up the shares folder, it failed because the folder is shared from another disk and the main ssd of my NUC is small and can’t backup everything. I resolved by requesting a snapshot without the shares backup and now everything works again.

I have the same issue but nothing is locking folders or files. Directly after a restart I started a snapshot and got this :

core-ssh:~# hassio sn new --name test
Error: 
core-ssh:~#

The logs said this:

INFO (MainThread) [hassio.api.security] /snapshots/new/full access from core_ssh
ERROR (MainThread) [hassio.snapshots] A snapshot/restore process is already running

I don’t know where to go from here to fix this, does anyone have an idea?

I was having the same problems recently. The problem is that once I click on the “Create” button on the UI, I get no feedback whatsoever that the backup process has started. If a check the logs, I can see that it backups for eg. the addons,
19-04-19 15:28:18 INFO (MainThread) [hassio.addons.addon] Finish snapshot for addon a0d7b954_grafana
but the process seems to never end. I also tried with the cli interface, with the “hassio snapshots new” command.
It turned out that you HAVE to wait until you get one of these responses:
19-04-19 15:39:17 INFO (MainThread) [hassio.snapshots] Full-Snapshot 166c141c done -in the logs
OR
core-ssh:~# hassio snapshots new
slug: 166c141c
-through ssh.
Otherwise your backup is still going on, and you should not terminate it in any way. My only issue is now that it takes an awful lot of time, probably because of the hardware limitations of my raspberry.

@ptrsz - The only problem I have with this solution is that It’s been a couple days since I last created a backup, so there is no backup process currently running.
