Re: dump failed: [request failed: No route to host](too)
It may well be just that I can't see the wood for the trees when looking at logging but I can't find the problem :-( I'm running daily manual dumps of the FAILED DLE's to keep backups intact! I'm still getting the following: FAILURE DUMP SUMMARY: bentley Resources lev 1 FAILED [too many dumper retry: [request failed: No route to host]] bentley sysadmin lev 1 FAILED [too many dumper retry: [request failed: No route to host]] Apart from the two KVM hosts, all these systems are KVM Guests. The backup server is a KVM guest. Has anyone seen or know of issues that may occur with amanda on virtualised infrastructure? From my understanding of KVM networking between guests, whole network frames are dumped and picked up between them. This allows higher transport speeds. I've tested the throughput with iperf and have seen througput as high as 25Gbps. The following ipef session shows the connection between the failed guest, bentley, and the backup server. I've only shown the 'server' side results for iperf below: # systemctl stop xinetd # iperf -p 10080 -s Server listening on TCP port 10080 TCP window size: 85.3 KByte (default) [ 4] local 10.0.19.21 port 10080 connected with 192.168.0.3 port 39214 [ ID] Interval Transfer Bandwidth [ 4] 0.0-10.0 sec 20.5 GBytes 17.6 Gbits/sec [ 4] local 10.0.19.21 port 10080 connected with 192.168.0.3 port 39215 [ 4] 0.0-10.0 sec 20.7 GBytes 17.8 Gbits/sec [ 4] local 10.0.19.21 port 10080 connected with 192.168.0.3 port 39218 [ 4] 0.0-10.0 sec 21.3 GBytes 18.3 Gbits/sec [ 4] local 10.0.19.21 port 10080 connected with 192.168.0.3 port 39223 [ 4] 0.0-10.0 sec 21.4 GBytes 18.4 Gbits/sec Any clues/help for the above are appreciated. I'm now also getting some other strange errors that I've never seen before. These report as 'FAILED' but further on into the report they appear to have completed without issue.

PARTIAL dump on my Fedora 26
Hi, Backup of my workstation are only partial, I need som help where to check. Are there a combination of more than one problem? Extract from the email-report: FAILURE DUMP SUMMARY: centos7.opistogo.se / lev 1 FAILED [data read: recv error: Resource temporarily unavailable] centos7.opistogo.se / lev 1 was successfully retried uw000140.kank.se /boot lev 0 FAILED [data read: recv error: Resource temporarily unavailable] uw000140.kank.se /boot lev 0 FAILED [data read: recv error: Resource temporarily unavailable] uw000140.kank.se /boot lev 0 partial taper: successfully taped a partial dump The client centos7 are on same subnet as the backup-server.

I mean "show the 2 dumptypes". You can always override the dumptype via "-o" commandline option, for example. I assume you talk about using amrecover? man 8 amrecover : read "Configuration override" Stefan
approaches to Amanda vaulting?
We are in the process of adding vaulting to our existing Amanda environment, and I am curious to hear/see how other sites have approached this. In particular, I'm curious what policies you have adopted for what gets vaulted, and how exactly you have scripted the vaulting so that you are sure the correct dumps always get copied the correct number of times, etc. In our situation, our nightly backups are to vtapes on a large internal drive, and our plan is to then vault to separate vtapes on external USB drives that are rotated physically each business day. So I think we don't want to use "vault-storage", since we want to let the nightly dumps proceeded without concern for whether the next USB drive is available yet. But what isn't clear is the best way to code a cron job to run later in the day, so that it keeps track of which of the nightly dumps have already been vaulted v.s. the ones that still need to be. But more generally, I'm just curious to see how various sites have implemented vaulting. Thanks.

Restore with a different dumptype
Hello, is it possible to create backups on node "A" with dumptype "A" and restore on a different host with dumptype "B"? The problem is, that host "A" uses some special tools which are not present on node "B" so I have to use another dumptype for restore. Thanks Matthias
