PgbackRest PointTIme Recovery : server unable to start back

List,

Reference: https://pgbackrest.org/user-guide-rhel.html#pitr
I am following the PTR on RHEL9 EPAS16.
I am able to do a backup(Full, diff and incr) and restore from a full
backup and restart of EPAS16 works fine.

But when I do an incremental backup after doing the procedures mentioned
in the PTR section of the above reference link and try restoring the EDB
database from the INCR backup and then starting up the EPAS16 the
server always results in dead state

My repo server is another machine. If I do a full restore on the DB
server ( sudo -u enterprisedb pgbackrest --stanza=Demo_Repo --delta
restore) it works and the server starts without any issue.
Restoring from Incremental backup tty output shows successful but edb
service start results in failure.

Any help is much appreciated.

Krishane.

STEPS followed:

after dropping the table pg-primary *⇒* Drop the important table
([section]
stopped the EDB server.

$ sudo -u enterprisedb pgbackrest --stanza=Demo_Repo --delta
--set=20240719-122703F_20240724-094727I --target-timeline=current
--type=time "--target=2024-07-24 09:44:01.3255+05:30"
--target-action=promote restore
