Re: PostgreSQL 9.3 PITR from remote server failing

[Rene Romero Benavides <rromero@xxxxxxxxxxxx>]

This line

scp: /bkp/wal/f%: No such file or directory

indicates that something's wrong with your recovery command, it should be 

/bkp/wal/%f

Hello,

I used WAL continuous Archiving to a remote backup server using the following command:

archive_command ='scp %p pgu@backup_server:/bkp/wal/%f && ssh pgu@backup_server "gzip /bkp/wal/%f"'

The wal is getting archived fine but the recovery fails when trying to restore using the following command:

restore_command ='ssh pgu@backup_server "gunzip /bkp/wal%f" && scp pgu@backup_server:/bkp/wal/%f %p'

The log file shows:

Here is the content of backup_server:/bkp/wal/ after I run the recovery. 00000002.history was 00000002.history.gz before.

[pgu@backup_server ~]$ ls -l /bkp/wal/

restoring from the local server works consistently using:

restore_command ='gunzip /bkp/wal/%f && cp /bkp/wal/%f %p'

Could you please help me with the appropriate restore command to recover from a remote server?

Thank you,
