Troubleshooting Backup & Restore¶
If you encountered errors, they possibly can be corrected.
Exit Codes¶
Our backup & restore scripts come with exit codes to help you finding a solution. However, we do not guarantee a complete error handling.
Beside the exit codes, there are also error messages returned to standard out.
Code |
Description / Situation |
---|---|
|
The script finished successfully (or the error is not handled). |
|
This is a general error. Most often used for script aborts due to incorrect information provided or information missing. |
|
There was an error with database handling. This usually either happens if your database server does not meet script requirements, login data being invalid or „broken‟ database dumps. |
|
There were issues with file / folder permissions. |
Classics¶
Here’s some classics you may encounter.
password authentication failed
orpeer authentication failed
This indicates that the password of your Zammad DB user is either different from your
database.yml
or the wrong database server may be contacted.- „But my Zammad instance is running, how can it be wrong?‟
Zammad may fall back to socket connection which is why you didn’t notice.
- What to do …
Ensure that the provided user credentials are correct. You can also consider to use the Database Helper: (re)set password script, you can find in the backup directory.
Ident authentication failed for user
This indicates your database server does require
ident
authentication. That authentication method is not supported by our scripts.- What to do …
Check
pg_hba.conf
of your PostgreSQL-Server and adjust it if needed.Usually authentication can be allowed like so:
# THIS IS A SAMPLE AND MAY NOT FIT YOUR ENVIRONMENT host all all 127.0.0.1/32 md5 host all all ::1/128 md5
Please consult the offical PostgreSQL documentation for this, as this is out of our documentation scope.
WARNING: You don't seem to have any attachments in the file system!
This indicate you’ve set
FULL_FS_DUMP
tono
but your instance currently does not save attachments to file system.This warning will be shown once before creating an empty directory to allow the backup process to continue successfully.
If you believe that this is an error, please see Storage Settings. In case the issue posts, please consult the Zammad Community.
