Los respaldos de MongoDB del módulo de NetWorker para bases de datos y aplicaciones (NMDA) fallan. El respaldo muestra lo siguiente:

monogdb_client:<save_set> size 0 KB, 0 file(s), took   0 min  31 sec

Se observa uno o más de los siguientes errores:

Cause

El script de respaldo está redirigiendo la salida a un archivo mediante >.

Resolution

Uso --out para la salida del archivo en lugar de dirigir la salida a un archivo.

Sección de script de ejemplo. Cambio:

(
set -x;
EXEC_MYWORK="$INSTANCE_PATH_MW16_MYWORK/mongodump -u $BACKUP_USER -p $BACKUP_PASSWORD --authenticationDatabase $BACKUP_AUTHDB --gzip --port 27020 --db local --collection oplog.rs --query \"{ts: {\\\$gt: {\\\$timestamp: {t: $PASS_TIME, i: 0}}, \\\$lt: {\\\$timestamp: {t: $CURR_TIME, i: 0}}}}\"  >  $OAPP_MOUNT_DIR/backup_data_Oplog";
eval $EXEC_MYWORK;
)

A:

(
set -x;
EXEC_MYWORK="$INSTANCE_PATH_MW16_MYWORK/mongodump -u $BACKUP_USER -p $BACKUP_PASSWORD --authenticationDatabase $BACKUP_AUTHDB --gzip --port 27020 --db local --collection oplog.rs --query \"{ts: {\\\$gt: {\\\$timestamp: {t: $PASS_TIME, i: 0}}, \\\$lt: {\\\$timestamp: {t: $CURR_TIME, i: 0}}}}\" --out $OAPP_MOUNT_DIR/backup_data_Oplog";
eval $EXEC_MYWORK;
