Hello List,

when i try to backup to DVD-RAM i get this error:

FAILURE AND STRANGE DUMP SUMMARY:
server md1 lev 0 FAILED [dump larger than tape, 30864683 KB, but cannot
incremental dump new disk]


How can i tell amanda to split it up in 4500MB slices and write them one
by one to DVD-RAM?

Here are the instresting config settings:
---------------------------------------------

dumpuser "root" # the user to run dumps under
inparallel 2            # maximum dumpers that will run in parallel
netusage  1024          # maximum net bandwidth for Amanda, in KB per
sec

dumpcycle 4 weeks       # the number of days in the normal dump cycle
tapecycle 8 tapes       # the number of tapes in rotation

bumpsize 20 MB          # minimum savings (threshold) to bump level 1 ->
2
bumpdays     1          # minimum days at each level
bumpmult     4          # threshold = bumpsize * (level-1)**bumpmult

runtapes     1         # explained in WHATS.NEW
tapedev "file:/media/dvdram"    # Linux @ tuck, important: norewinding

tapetype DVD47G         # what kind of tape it is (see tapetypes below)
labelstr "^daily-[0-9][0-9]*$"  # label constraint regex: all tapes must
match

diskdir "/backup/tmp"           # where the holding disk is
disksize 5000 MB                    # how much space can we use on it



infofile "/var/lib/amanda/DailySet1/curinfo"    # database filename
logfile  "/var/log/amanda/DailySet1/log"        # log filename

indexdir "/var/lib/amanda/DailySet1/index"


holdingdisk hd1 {
    comment "main holding disk"
    directory "/backup/tmp/"      # where the holding disk is
    use 5000 Mb
}

define tapetype DVD47G {
     length 4350 MB
     filemark 4KB
}


Any ideas?

 Thanks, Mario
