Backup does not finish "ERROR: Backup failed issuing start backup command."

Good morning guys. I have a backup that doesn't finish and I'm getting the following error:
Asking the PostgreSQL server to finish the backup.
ERROR: The backup failed to issue the backup start command.

No packages

The barman diagnose command has minor modifications for confidentiality.

Thank you all for your help. I'm learning a lot and I like this group more and more every day. I hope that soon I can help and contribute my little knowledge.

Hi Jose,

It's puzzling that the connection to PostgreSQL fails during the backup but succeeds during the `barman check` command. I would start by looking at the PostgreSQL server logs and the Barman server logs during the `barman check` command and then comparing them to the same during the `barman backup` command - are there any signs of the connection failing during the check and needing to be re-established?

Is the connection consistently failing at the same time during the backup?

Best,

Mike

Anything in the PostgreSQL logs that can explain what if failng? Could
it be a permission issue?
Can you try to connect via psql to PostgreSQL and issue, as barman
user, pg_start_backup() and see if there is some hint about the
problem?

I have launched a new backup with "barman --log-level DEBUG backup bidb" to see if it gives us more clues.

thanks

I have no idea what is going on as the network traffic is not cut off at any time.

[Jose Manuel Valseca Echevarria]

Is it possible to re-establish the communication if it has been momentarily lost or continue with the copy if it has failed, or is it necessary to launch a new one?

I can't manage to make a complete copy

thanks

AFAIK no, this is a feature available for example in pgbackrest but
barman will start a backup copy from scratch every time.

This is the error that appears in the log. What do you think could be wrong?
What is the command you are referring to? "barman.backup ERROR: Backup failed issuing start backup command"

Good morning guys. The Network department has monitored the network during the whole copying process and it is not a network problem.
On the other hand I have the following information from the database:

edb=# \c bidb

Password for user enterprisedb:

You are now connected to database "bidb" as user "enterprisedb".

bidb=# show tcp_keepalives_idle;

tcp_keepalives_idle

---------------------

0

(1 row)

bidb=# show tcp_keepalives_interval;

tcp_keepalives_interval

-------------------------

0

(1 row)

bidb=# show tcp_keepalives_count;

tcp_keepalives_count

----------------------

0

(1 row)

 

Please help me. I don't know what is going on and I have been without copies for 2 weeks.

Best regards and thanks

[Jose Manuel Valseca Echevarria]

This meks me think that you could be using the exclusive backlup
instead of the concurrent one, could it be a start backup is still in
progress?
But I don't know how to check without issuing manually a
pg_stop_backup and start over a new backup.

This is something custom, right? Any chance this is keeping the backup to fail?

Luca

[Jose Manuel Valseca Echevarria]

These scripts are to notify the final status of the copy. If you need it, I can put a copy here.
Could you tell me how to do the pg_stop_backup by hand, what steps do you want me to do to recreate the error?

Best regards

I would connect to postgresql and execute a pg_stop_backup, something like:
psql -U postgres -c 'SELECT pg_stop_backup();'
and see if it complains about no backup in progress, then start over a
new backup and see what happens.

Luca

[Jose Manuel Valseca Echevarria]

I get the same result

edb=# SELECT pg_stop_backup();'
ERROR: no hay un respaldo exclusivo en curso

This means there is no backup in progress, then barman should work. If
not, I've at the moment no particular idea.
