java system backup

[Former Member]

Hi,

what is the procedure for sap java standalone system backup. as per my knowledge, we need to take a backup of:

1. java database

2. file strucute (sdm) for configuration data

can any one provide me the complete document or steps to perform the standalone java system backup.

Thanks,

Niranjan.

Hi,

For Java system becakup you need to have backup of database + File system.

Java files which will be required are

SDM

bootstrap.properties file

instance.properties file

To perform above backup you need to ensure system is stopped with its services.

for File system backup you should perform backup of usr/sap/sid directory complete to be in safe side

Hope this will clarifies

hi Niranjan V,

i have followed follow the steps for backup in my landscape, the first procedure is the SAP recommended one for consistent backup for sap systemsand the second procedure may take more space, but it is very easy to recover the system in short time.

1) take a backup by sapinst ( master installer ) is know as system copy.

( or )

2) take another backup by file strucute (sdm) for configuration data

a ) disable all sap and oracle services at OS level

b ) take copy of whole of usr directory into a seperate folder ( ex: bi_backup_01242009)

c ) take copy of whole of oracle directory into the folder ( ex: bi_backup_01242009)

note : all sap and oracle services should be disabled in services.msc in windows. where as in unix stopsap commnad stops all sap and oracle services please check if not stopped any one of the services ( processes) kill it.

these are the complete steps for file strucute (sdm) for configuration data

you have take the offline file backup by the following steps

1) down the sap instance by the command -> stopsap (unix) / MMC (windows)

2) i have created the the floder named ->ex: aed_file_backup_042409 in AED_Backup folder

2) /usr/sap entire folder

3) /oracle/AED entire folder except 102_64, desktop

thank you,
