Amanda File Recovery
Configuration We'll be using amrecover(8) to recover files from backup. Before we can recover files, a little more configuration is in order. Amrecover is technically a client tool, and contacts the server to "pull" the recovery down to the client. You'll recall this is the reverse of the backup situation, where the server contacts the client to ask for its data. As such, we'll need to configure the client to talk to the server. Put the following in /etc/amanda/amanda-client.conf:
index_server "localhost" tapedev "changer" auth "local"
There, that wasn't so bad.
Start the Recovery Amrecover will recover into subdirectories of the current directory. It's good form to run amrecover in an empty directory, so (as root):
mkdir /tmp/test-recovery cd /tmp/test-recovery
amrecover runs as root, since it's restoring files and permissions - something a non-root user can't do. It's time to start amrecover:
You should sget this
Using index server from environment AMANDA_SERVER (knuth) AMRECOVER Version 3.2.1. Contacting server on knuth ... 220 knuth AMANDA index server (3.2.1) ready. Setting restore date to today (2011-01-01) 200 Working date set to 2011-01-01. 200 Config set to MyConfig. 501 Host knuth is not in your disklist. Use the sethost command to choose a host to recover amrecover>
Amrecover tries to be useful and guess the hostname you want to restore. We used "localhost" instead of "knuth", so this guess didn't work out. That's OK, though! You just need to tell amrecover what host to use.
amrecover> sethost localhost
With this result
200 Dump host set to localhost.
and let's narrow in and recover the latest backup of 'groups':
amrecover> setdisk /etc 200 Disk set to /etc. amrecover> add * (this will add all subdirctories)Then lets extract it outamrecover> extract Extracting files using tape drive changer on host knuth.

Y Restoring files into directory /root All existing files in /root can be deleted Continue [?/Y/n]? Y Hit control-d to exit amrecover, and there's your file:That's nice and easy, isn't it?
