Hello Gene, thank you for your answere. Now our backup server is dumping with 100 inparrallel dumpers.
One thing you have to explain a bit further to an non-native-speaking person: "probably newer than your install as I play the part of the geriatric (76 yo) canary in this here coal mine. ;-)" How are we? Lets say that we are a public enterprise hosting some servers for other plublic enterprises. How big is our amanda installation? amanda@...:~$ amadmin daily hosts |wc -l 100 amanda@...:~$ amadmin daily dles |wc -l 233 amanda@dl380-54:~$ amadmin daily balance due-date #fs orig MB out MB balance ---------------------------------------------- 7/23 Sat 8 472004 165476 +2.0% 7/24 Sun 2 137758 60193 -62.9% 7/30 Sat 8 472004 165476 +2.0% 7/31 Sun 147 4358003 3126873 +1827.8% 8/01 Mon 6 215482 163543 +0.8% 8/02 Tue 6 235070 120318 -25.8% 8/03 Wed 9 39854 25501 -84.3% 8/04 Thu 1 212948 40739 -74.9% 8/05 Fri 4 66 59 -100.0% 8/06 Sat 8 472004 165476 +2.0% 8/07 Sun 3 174102 91387 -43.7% 8/08 Mon 17 191009 85464 -47.3% 8/09 Tue 2 285718 91829 -43.4% 8/10 Wed 1 165080 51475 -68.3% 8/11 Thu 12 11078 5933 -96.3% 8/12 Fri 3 3617 949 -99.4% 8/13 Sat 8 472004 165476 +2.0% 8/14 Sun 2 137758 60193 -62.9% 8/15 Mon 2 3183 1468 -99.1% 8/16 Tue 2 340170 92741 -42.8% 8/17 Wed 12 221551 185296 +14.2% ---------------------------------------------- TOTAL 263 8620463 4865865 162195 DISTINCT 233 6791177 4188858 (estimated 30 runs per dumpcycle) I think it isnt quiet so big, but there will be more in the future. Why di d I want to increase this option? Because of some clients with lots of data to get through in the nightly backup window. Before this, it could happen that the bigger ones were dumped to late in the night. BTW does anyone understand how the dumporder option really works; do I have to set it for every dumper? In comparison to this the tapeorder option is better to understand...
