In our case at 3.5GB on one disk and 700MB on the other.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">After getting Dell to replace the TL2000, upgraded firmware for the library and the drive, used the latest drivers from DEll and<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">from IBM as its a IBM rebranded library and drive still the same problem.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Patched up all the hotfixes i could find at the time, SP1 of DPM 2007 too. Still no joy.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This doesn&#8217;t make sense as the backup is from the DPM replica to tape, it is NOT connecting to the original host.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>SOLUTION\/WORKAROUND:<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">I was with our Anti-virus guy (Kaspersky) and was discussing the problem, although i&#8217;d given him the list of the DPM volume<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">mount points used to exclude from the scan the AV software still scanned the replica and volume shadow copies on the DPM server.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">I retried the failed job and waiting, about 5 seconds before the tape job failed the AV detected 3 virsues on the disk and tried<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">to delete them, as its in a volume mount point, it couldn&#8217;t and therefore blocked access, 10 seconds later the tape backup job reported failed.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">So that was it the AV was causing the problem. Removed the AV software (to test) and reran the job went through no problems.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Now we have working backups the challenge is to get them to work with the AV installed (Kaspersky in our case)<\/p>\n","protected":false},"excerpt":{"rendered":"<p>PROBLEM: The operation failed because of a protection agent failure.
