You must use the 'amoldrecover' command.

amoldrecover must be used to talk to older server.

We have an Amanda backup server running 2.4.4, we are able to run amrecover on this system:

But when we try to run amrecover on a new backup client, it gives us these errors:

# amrecover Daily

AMRECOVER Version 2.5.1p1. Contacting server on backup.videopropulsion.com ...

NAK: unknown service: amindexd

The /etc/amanda/amanda-client.conf file contains:

conf "Daily"

tape_server "backup.videopropulsion.com"
tapedev "file:/var/backup/Daily"
auth "bsd"

The amrecover*debug file under /var/log/amanda/client/Daily contains:

NOTE: /etc/amanda/Daily/amanda-client.conf is a empty file.

The old backup server doesn't have any auth= lines in the amanda.conf file.

Can we use then newer Amanda client programs (2.5.1) to recover files from an older Amanda Backup server (2.4.4)?

If we should be able to use the newer Amanda client programs, what do we need to do to resolve this problem?

Amanda 2.4.4 has been able to create backups on the old backup server from the new server.
