Plesk backup at Tools & Settings > Backup Manager finished with the following warning:
PLESK_WARN: Warning: Extension "Grafana"
Unable to back up extension package. Error: Failed to create archive: Failed to close volume: (5) Input/output error -
The backup directory is located on an Amazon S3 storage mounted as a drive:
# df -h
Filesystem Size Used Avail Use% Mounted on
...
s3fs 256T 0 256T 0% /var/lib/psa/dumps
Cause
Amazon S3 storage is not using a POSIX-compliant file system, that is why it is not recommended to mount it as a backup storage drive.
Resolution
Consider the following alternatives:
- Use Amazon S3 Backup extension for storing backups in remote S3 storage.
- Mount storage with a POSIX-compliant filesystem such as Amazon EFS.
