pg_dump backup is available and archive logs are also configured....

Could you please confirm?  Thanks in Advance!!

Hi Pavan,

PITR is the ability to restore a database cluster up to the present or to a specified point of time in the past with the help of WAL’s.  PITR uses full database cluster backup and the write-ahead logs(i.e WAL’s). For that we should have cluster level (file system level) backup like pg_basebackup.

In PostgreSQL it is possible to have PITR but it requires file system level backup (like pg_basebackup).
So, It is not possible to do PITR with pg_dump backup.

Hi Shreeyansh,

Thanks for confirmation. Actually did PITR with basebackup. 

Wanted to know if it could be done by using dump bkp.

Anyways, thanks for confirmation

Since pg_dump is logical, it won’t provide the basis for PITR.  A number of other tools will.

There is a good discussion of the capabilities of most of the PostgreSQL backup tools here:

Hi Pavan,

Is it not possible with the pg_dump backup and with the wal files.

to do he PITR we need the pg_base backup along with WAL files.
