Overview
Sometimes you have to upgrade your backupserver.
This article describes, how to migrate from an old amanda version (amanda-server-2.4.4p2-3) to the current version (amanda-server-2.5.1p3).
Backup jobs
The default backup job is e.g. DailySet1.
Amanda store the configuration data for this backup job in /etc/amanda/DailySet1: e.g. /etc/amanda/DailySet1/amanda.conf
The Amanda database data for this backup job is stored in /var/lib/amanda/DailySet1.
The file index for backup data is stored in /var/lib/amanda/DailySet1/curinfo/HOST/DISK.
Startpoint
After 3 years of using amanda 2.4 there was time for updating the whole server.
On a new server with Fedora Core 6 I installed amanda 2.5 with the old DLT-tapedrive.
I configured the new server and tested the backup with a small backupjob.
In /etc/amanda/DailySet1/amanda.conf there is to change your basic configuration like
- runtapes
- tapedev
- tpchan
- infofile "/var/lib/amanda/DailySet1/curinfo"
- logdir "/var/lib/amanda/DailySet1"
- indexdir "/var/lib/amanda/DailySet1/index" ger
- tape type
- labelstr
- infofile "/var/lib/amanda/DailySet1/curinfo"
- logdir "/var/lib/amanda/DailySet1"
- indexdir "/var/lib/amanda/DailySet1/index"
- ...
Problems with amrecover from amanda 2.5
amrecover reported always:
NAK: user root from europa.lmetrix.de is not allowed to execute the service amindexd: Please add "amindexd amidxtaped" to the line in /var/lib/amanda/.amandahostsd" to the line in /var/lib/amanda/.amandahosts
After adding
server.fqd root amindexd amidxtaped
amrecover worked.
Keep an eye on /etc/xinet.d/amanda
service amanda { socket_type = dgram protocol = udp flags = IPv4 wait = yes user = amanda group = disk server = /usr/lib/amanda/amandad # server_args = -auth=bsd amdump amindexd amidxtaped disable = no }
Transfering data
In the parameter in /et/amanda/DailySet1/amanda.conf
- infofile "/var/lib/amanda/DailySet1/curinfo"
- logdir "/var/lib/amanda/DailySet1"
- indexdir "/var/lib/amanda/DailySet1/index"
is defined, where amanda stores his process data.
Therefore I transfered the data
- tapelist
- index
- curinfo
from the old server to the new server.
