Re: Trying to backup to disk, getting "dump to tape failed, will try aga

I think I'm getting closer to the problem. There seems to be aconnection issue between my server and client. If anyone has any input,I'd appreciate it. I've got iptables on my client set up to accept port10080 connections from my server, and it's obviously talking a bit sinceI have logs on my client. So...?


Taking a closer look at the amdump log on my backup server, I see:

Hi there,

I'm new to Amanda and am trying to get a disk-to-disk backup going.When I run amcheck, everything seems fine. Then, when I run amdump,nothing ever gets written to disk (virtual tape). The amanda log fileshows:

SUCCESS taper [hostname] /export/backup 20071126 0 [sec 188.985 kb 0kps 0.0 {wr: writers 0 rdwait 188.984 wrwait 0.000 filemark 0.000}]INFO driver [hostname] /export/backup 0 [dump to tape failed, will tryagain]

I've googled and read docs and how-to's to get where I am now.Unfortunately, all the docs and how-to's get me to running amcheckwithout errors and then launch into how to start a recovery process.I guess that means that most people have no problems with amdump. ;-)I've included config info below, amanda.conf, disklist, etc. Pleasetake a look and let me know what silly error I've made. I'd reallyappreciate it. If I've left out some pertinent info, please tell meand I'll include it.


Thanks!!

My amanda.conf file is
org "OrgName" # your organization name for reports
dumpuser "amanda" # the user to run dumps under

inparallel 4 # maximum dumpers that will run in parallel

dumpcycle 14 # the number of days in the normal dump cycle
runspercycle 10 # the number of amdump runs in dumpcycle days
etimeout 55 # number of seconds per filesystem for estimates.
runtapes 1 # number of tapes to be used in a single run of amdump
tapetype HARDDISK # what kind of tape it is (see tapetypes below)

labelstr "^OrgName-[0-9][0-9]*$" # label constraint regex: all tapesmust match


tapecycle 11
tpchanger "chg-disk"

define tapetype HARDDISK {
   comment "Dump onto hard disk"
   length 40960 mbytes
}

define dumptype global {
   index yes
   program "GNUTAR"
   exclude list "/var/lib/amanda/exclude.gtar"
   # record no
}

define dumptype hard-disk-dump {

}

define interface vbeb {
   comment "10 Mbps ethernet over the vbeb"

And my test disklist file looks like this:

client.host /export/httpd/beta-webspaces hard-disk-dump -1 vbeb
client.host /export/httpd/swc.bluefrog hard-disk-dump -1 vbeb

I have my virtual tapes set up and labeled:
