More than likely your keep_wal_segments setting is too low. How long is the pg_basebackup taking? Remember that segments are generated about every 5 minutes, so if the backup takes an hour, you need at least 12 segments stored. At 2 hours, you need 24 etc., I'd set the value to about 12.2 segments/hour of backup.

Hi
I am a newbie to postgres. We are on postgres 9.1 running on RedHat 6. When we do the postgres backups we are noticing the following errors
pg_basebackup: could not get WAL end position from server: FATAL: requested WAL segment 000000010000020B00000040 has already been removed
But when I look into pg_xlog, I notice
000000010000020B00000040.00000118.backup
May I know how to resolve this error? Are the backups done with these errors, recoverable?
Thanks in advance for your support.
Thanx,
Sam
