Hi admins, I have the following situation:
Cluster located at $PGDATA
Two extra tablespaces located in $PGTBS/tbs_laboratorio_02 and $PGTBS/tbs_recetas respectively.
I could generate a base and one incremental backup succesly. Both using --tablespace-mapping options, like the next commands
[postgres@buda ~]$ pg_basebackup -c fast -D $PGBKP/fisicos/base_plano -R -P
--tablespace-mapping=$PGTBS/tbs_laboratorio_02=$PGBKP/fisicos/base_plano/tbs_laboratorio_02 \
--tablespace-mapping=$PGTBS/tbs_recetas=$PGBKP/fisicos/base_plano/tbs_recetas
[postgres@buda ~]$ pg_basebackup -c fast -P -D $PGBKP/fisicos/viernes --incremental $PGBKP/fisicos/base_plano/backup_manifest \
--tablespace-mapping=$PGTBS/tbs_laboratorio_02=$PGBKP/fisicos/viernes/tbs_laboratorio_02 \
--tablespace-mapping=$PGTBS/tbs_recetas=$PGBKP/fisicos/viernes/tbs_recetas
And now I'm trying to combine y get a full backup using pg_combinebackup, but I'am getting errors. I'm assuming the commando need to map de 4 tablespace ditectorys generated throug base backup and incremental backup
The $PGBKP/fisicos/restore exists and is empty, before and after the command execution.
[postgres@buda ~]$ pg_combinebackup $PGBKP/fisicos/base_plano $PGBKP/fisicos/viernes -o $PGBKP/fisicos/restore \
--tablespace-mapping=$PGBKP/fisicos/base_plano/tbs_laboratorio_02=$PGBKP/fisicos/restore/tbs_laboratorio_02 \
--tablespace-mapping=$PGBKP/fisicos/base_plano/tbs_recetas=$PGBKP/fisicos/restore/tbs_recetas \
--tablespace-mapping=$PGBKP/fisicos/viernes/tbs_laboratorio_02=$PGBKP/fisicos/restore/tbs_laboratorio_02 \
--tablespace-mapping=$PGBKP/fisicos/viernes/tbs_recetas=$PGBKP/fisicos/restore/tbs_recetas
pg_combinebackup: error: can't create directory «/var/lib/pgsql/17/backups/devadv01/fisicos/restore/tbs_recetas»: The file already exists

I'm at a dead end
Thanks in advance
