NetWorker: Il backup MongoDB con NMDA non riesce

I backup MongoDB di NetWorker Module for Databases and Applications (NMDA) non riescono. Il backup mostra:

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

Vengono osservati uno o più dei seguenti errori:

The size of proxied data written has not been set. Backup of ssid 'xxxxx' failed due to unrecoverable errors.
The read operation returned a value of -1. Error code: 5. Error: Input/output error.
Backup of ssid 'nnnn' failed due to unrecoverable errors
The backup command '/nsr/apps/config/backup_logscript.sh' did not complete successfully: Backup of ssid 'nnnn' failed due to unrecoverable errors. 

Lo script di backup reindirizza l'output a un file utilizzando >.

Utilizzare --out per l'output del file invece di indirizzare l'output a un file.

Sezione di script di esempio. Cambiare:

(
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;
)
