SAP Note
Header Data
Symptom
You would like to schedule database backups of SAP HANA Database
including back up of the database configuration files using the
Linux cron daemon or other scheduling tools.
Other Terms
HANA Backup
Reason and Prerequisites
A complete backup of SAP HANA Database includes the data backup
and in addition a backup of the configuration files. A standard
functionality to combine data and configuration backup is not
provided as part of SAP HANA Database
Solution
The attachment to this SAP Note contains a linux shell script
(bash) that demonstrates how one can create data and configuration
backups of SAP HANA Database from the linux command line. If
parameterized appropriately, this linux shell script can be used
for scheduling database backups e.g. via the Linux cron daemon. The
second attachment to this SAP Note contains a detailed description
of the shell script, including all command line options and
adjustable parameters. Features of the shell script (partial):
l Create data backup and / or configuration file backup
l Fully configurable backup target locations
l Either write backup to files with unique file names per day of
the week (i.e. keep backup files for one week, then files are being
overwritten); or into a user configurable file name
l Statistics collection of backup size and time to execute
backup in a csv file on the database server.
l Using the secure hdbuserstore for authetication against SAP
HANA Database
l As of version 3 (June 2013), the script also handles copies of
the backup catalog as described in SAP Notes 1812980 and
1852242.
For full details see the attached documentation file. Please
note: the script is only intended to demonstrate how backup control
could be implemented. The responsibility to implement a backup
solution appropriately lies with the implementation team. The
script is also not intended to replace other scheduling mechanisms
for database backups of SAP HANA Database such as the scheduling
calendar of dbacockpit.
