(Yes / No): - When did this problem seem to first start? - Installation method _(e.g. AlO, NCP, Bare Metal/Archive, etc.)_ - Are you using CloudfIare, mod\_security, or similar? _(Yes / No)_ ### Summary of the issue you are facing: This is the third time Borgbackup stops doing the backup because the lock file is present. The first time i removed the lock and backups continued normally. On a periodic check, i discovered last monday that backups where again stuck since 10 days. I removed the lock, did a manual backup, an integrety check. When restarting all the containers where updated. First night, the backup was Ok, but today it was again stuck. This is the end of the backup log : 2026-09-17T03:03:00.519020726Z Compacting additional host mounts… 2026-09-17T03:03:01.192986219Z Backup finished successfully on 17.09.2026 - 03:03:01 (00 hours 01 minutes 37 seconds). So hter should be no reason why the lock was still there. Steps to replicate it (hint: details matter!): 1. I don’t see a way to replicate the problem 2. 3. ### Log entries #### Nextcloud Please provide the log entries from your Nextcloud log that are generated during the time of problem (via the _Copy raw_ option from _Administration settings-\>Logging_ screen or from your `nextcloud.log` located in your data directory). Feel free to use a pastebin/gist service if necessary. ```auto 2026-09-17T03:05:00.544854241Z 2026-09-17T03:05:00.544857128Z Total reclaimed space: 5.488GB 2026-09-17T03:06:00.629711629Z ++ head -1 /mnt/docker-aio-config/data/daily_backup_time 2026-09-17T03:06:00.630534108Z + BACKUP_TIME=03:00 2026-09-17T03:06:00.630555718Z + export BACKUP_TIME 2026-09-17T03:06:00.630564795Z + export DAILY_BACKUP=1 2026-09-17T03:06:00.630572404Z + DAILY_BACKUP=1 2026-09-17T03:06:00.630868614Z ++ sed -n 2p /mnt/docker-aio-config/data/daily_backup_time 2026-09-17T03:06:00.631856957Z + '[' '' '!=' automaticUpdatesAreNotEnabled ']' 2026-09-17T03:06:00.631884138Z + export AUTOMATIC_UPDATES=1 2026-09-17T03:06:00.631889335Z + AUTOMATIC_UPDATES=1 2026-09-17T03:06:00.632122721Z ++ sed -n 3p /mnt/docker-aio-config/data/daily_backup_time 2026-09-17T03:06:00.632793591Z + '[' '' '!=' successNotificationsAreNotEnabled ']' 2026-09-17T03:06:00.632810382Z + export SEND_SUCCESS_NOTIFICATIONS=1 2026-09-17T03:06:00.632814553Z + SEND_SUCCESS_NOTIFICATIONS=1 2026-09-17T03:06:00.632817967Z + '[' warn '!=' debug ']' 2026-09-17T03:06:00.632856469Z + set +x 2026-09-18T03:00:07.552943658Z Daily backup script has started 2026-09-18T03:00:07.673696058Z Connection to nextcloud-aio-apache (172.18.0.12) 11000 port [tcp/*] succeeded! 2026-09-18T03:00:07.730696807Z Starting mastercontainer update... 2026-09-18T03:00:07.730741380Z (The script might get exited due to that.
