History database is not updated

Help
1

I just started to use Atuin, It’s great so far, thanks!

I’m now trying to sync two machines with a self hosted server with sqlite, using same username, same key. The problem I’m seeing is that a new machine (hostNew) does not have the existing machine (hostOld) history.

Both hostOld and hostNew has 18.8.0, sync.records=true. doctor results are same except the timestamp.

{
  "atuin": {
    "version": "18.8.0",
    "sync": {
      "cloud": false,
      "records": true,
      "auto_sync": true,
      "last_sync": "2025-09-24 16:18:38.915643436 +00:00:00"
    },
    "sqlite_version": "3.46.0"
  },
  "shell": {
    "name": "zsh",
    "default": "zsh",
    "plugins": [
      "atuin"
    ],
    "preexec": "built-in"
  },
  "system": {
    "os": "CentOS Stream",
    "arch": "x86_64",
    "version": "9",
    "disks": [...

The key and decryption seems ok. atuin store status results are identical (except CURRENT HOST marker and the slight differences of idx because of atuin store status executions.

$ atuin store verify
Verifying local store can be decrypted with the current key
Local store encryption verified OK

$ atuin store status
host: hostOld-ID
        store: history
                idx: 1359925
                ...
host: hostNew-ID
        store: history
                idx: 76

The significant difference is the number of items in history database.

On hostOld

$ atuin sync
0/0 up/down to record store
Sync complete! 147197 items in history database, force: false

On hostNew

$ atuin sync
0/0 up/down to record store
Sync complete! 341 items in history database, force: false

New command history in global mode is working.

For example, hostOld → hostNew

  1. Run foobarbaz on hostOld
  2. atuin sync on hostOld
  3. atuin sync on hostNew
  4. atuin search -i foobarbaz on hostNew
  5. See Inspect → foobarbaz command stats has Host hostOld as expected

Also the opposite direction (hostNew → hostOld) is working.

The problem is that hostNew does not display hostOld history, the ~150k items.

atuin store rebuild history, atuin store pull --force, delete ~/.local/share/atuin/ and start over, nothing did not change this behavior so far.

Is there anything I can try to fix it or investigate it further?
