I tried to use ampgsql to backup mu "personal" database cluster (over a

This create two properties of the dumptype, you want application properties:
It is a bug to use the 'PG-' prefix on the application properties.
The 'PG-' prefix must be use only if you define the properties in
amanda-client.conf, don't do it, it is deprecated.
define dumptype ampgsql-local {
gnutar-local # You might need this if you're setting 'auth
"bsdtcp"' in your global dumptype settings, for example
program "APPLICATION"
application {
app-ampgsql
property "ARCHIVEDIR" "/var/lib/postgresql/archive" # not required, it
is set in app-ampgsql
property "DATADIR" "/var/lib/postgresql/9.1/main" # you could set it
in app-ampgsql
}
}
disklist
--8<---------------cut here---------------start------------->8---
localhost postgres ampgsql-local
--8<---------------cut here---------------end--------------->8---
(example from howto was foo.example.com bar dt_ampgsql)
But this did not work :(
After read some debug and log files I found that tar called from ampgsql
tries to backup "postrgresql" dir which was clearly wrong.
then I changed disklist to
--8<---------------cut here---------------start------------->8---
localhost postgres /var/lib/postgresql/9.1/main ampgsql-local
--8<---------------cut here---------------end--------------->8---
And this seems to work. (At least dump contents looks reasonable)
But
1. Am I misssed something about cluster data dir in dikslist?
2. If I have to use diskdevice in disklist entry - what for is "PG-DATADIR"?
Either the diskdevice in disklist or the DATADIR application property.
