I want to Restore the H-Sphere System Database From Backup.

Plz. help

You can restore the H-Sphere system database from the backup made by the H-Sphere hs_bck script. If you back up your system PostgreSQL database manually using pg_dump, the procedure would be basically the same, except for the names and locations of the backed up system databases.

The backup destination directory for the /hsphere/shared/backup/hs_bck script is set in the /hsphere/shared/backup/hs_bck.cfg config file. The default location is:
BCK_DIR /var/backup

hs_bck stores the system data backup in the following files in the BCK_DIR directory:

<ARCHIVE>.tgz – the system data content; <ARCHIVE> is the name of the backup file set in hs_bck.cfg:
BACKUP hs_bck
Older backup files are named <ARCHIVE>.1.tgz, <ARCHIVE>.2.tgz, …
hsphere.sql – the H-Sphere system database backup;
counter.sql, poll.sql, guestbook.sql – SiteStudio system databases are also backed up if SiteStudio is integrated with H-Sphere.

I. Restoring the H-Sphere database on a server where PostgreSQL is not installed:

Log in to the server as root:
su –
Install PostgreSQL to the server.
Start PostgreSQL for the first time:
On RedHat servers:
/etc/rc.d/init.d/postgresql start
On FreeBSD servers, you need to inititiate the PostgreSQL service database manually before you start Postgres:
su – pgsql -c initdb
/usr/local/etc/rc.d/010.pgsql.sh start
Log in as PosgreSQL user:
On RedHat servers (the PostgreSQL service database is initiated automatically on login):
su – postgres
On FreeBSD servers:
su – pgsql
Create the user wwwuser:
createuser wwwuser
Answer yes to all prompts.
Enter the PostgreSQL service database:
psql tempate1
Restore the wwwuser password:
alter user wwwuser with password ‘old_password’;
alter user pgsql with password ‘old_password’;
Here, old_password is the wwwuser password to be restored.
Quit from PostgreSQL:
q
Configure PostgreSQL passwords in the ~pgsql/data/pg_hba.conf file, according to instructions provided in this file.
Here it may be also helpful to optimize H-Sphere memory usage for better PostgreSQL performance.
Restart PostgreSQL.
Create H-Sphere database:
createdb -U wwwuser hsphere
SiteStudio databases are created in the similar way.
Import the database content from the backup:
psql -U wwwuser -f <HS_BCK>/hsphere.sql hsphere
where <HS_BCK> is the backup directory. SiteStudio databases are imported in the similar way.

II. Restoring the H-Sphere database content if the database already exists:

Log in to the CP server as root:
su –
Drop the H-Sphere database:
dropdb -U wwwuser hsphere
Create the H-Sphere database:
createdb -U wwwuser hsphere
Import the database content from the backup:
psql -U wwwuser -f <HS_BCK>/hsphere.sql hsphere
where <HS_BCK> is the backup directory.
SiteStudio databases are restored in the same way.
