Resolution

Verwenden Sie --out für die Dateiausgabe, anstatt die Ausgabe an eine Datei weiterzuleiten.

Beispiel für einen Skriptabschnitt. Veränderung:

(
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;
)

Zu:

(
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;
)
