Re: Restore backuppc installation (localhost) from existing backuppc backups

After installing the backuppc software (or at least copy of 
BackupPC_tarExtract) you should be able to do

BackupPC_tarExtract -host <hostname> -num <backup_number> -path 
/path/to/file > extracted_file

Extracting files from cpool is extremely painful - you have to find a full 
backup from "backups" file for your host, then hash in pc/ directory, then 
find the hash in cpool, then extracting the zlib compressed file (with 
like pigz)... and maybe you can get something useful. For backuppc 4+ this 
is even worse...

Since the external drive includes the backup for localhost (the former box running backuppc), it should include a backup for /etc/backuppc and the config.pl file (I forget which directories I set for backup for localhost; hopefully I included /etc).
