Yes, it does. shat only takes a few minutes though. Look at line 6 in the above URL: 16-Feb 00:12 tape01-sd JobId 231188: Sending spooled attrs to the Director. Despooling 422,031,119 bytes ... Then look at line 204: 16-Feb 00:15 bacula-dir JobId 231187: Bacula bacula-dir 7.4.0 (16Jan16): I think attribute spooling takes only 3-4 minutes. If you look at the URL, you can see that reading and sending the data takes up the rest of the job. Line 2-3: 15-Feb 13:23 tape01-sd JobId 231188: Spooling data ... 15-Feb 22:59 tape01-sd JobId 231188: Committing spooled data to Volume "000003L4". Despooling 333,554,921,501 bytes ... Spooling takes 9.5 hours. Line 4: 16-Feb 00:12 tape01-sd JobId 231188: Despooling elapsed time = 01:13:23, Transfer rate = 75.75 M Bytes/second Writing 334GB to tape takes about 13 minutes. -- Dan ------------------------------------------------------------------------------ Site24x7 APM Insight: Get Deep Visibility into Application Performance APM + Mobile APM + RUM: Monitor 3 App instances at just $35/Month Monitor end-to-end web transactions and take corrective actions now Troubleshoot faster and improve end-user experience.
