Database recovery from tablespace only

Hey Hackers,

We had a database running on debian where its disks went corrupted. And
currently is not possible to access those disks, unreadable.

For backup we used:

File System Level Backup
Continuous Archiving and Point-in-Time Recovery (PITR)

We used tablespaces for the entire database.

When trying to recover from the backup we noticed that the backup was
partially complete, here is the info:

PG_VERSION 8.2.4

base we are missing the files

global we are missing the files

pg_clog we are missing the files

pg_multixact we are missing the files

pg_subtrans we are missing the files

pg_tblspc All files are preserved there from a backup

pg_twophase we are missing the files

pg_xlog we are missing the files

Previous backups had the same error. We only have backups from the last 2
weeks.

We have a very old (about 10 years old) data/

What are the alternatives for recovery here? (besides trying to recover
disk data with specialists)

Thanks!

Phillip Black.
