Restoring event archives

In general, we know what are the best practices to take the backup of Event Archieve & what policies to maintain for backing up the huge amount of Event archieve data. becoz this is the part of our routine activity.

As Event Archieve data is the most imp. data for SSIM not only backing up the Event archieve data is imp.

It's more imp. to restore this data at the time of disaster. here i have tried to explain in small chunk to restore the Event archieve data.

First of all you need to have the backup tapes handy or you can simply inform your backup admin to restore the Event archieve data on particular computer:

In General, You can view events from archives copied from other computers.

To view the archives copied from another computer you must copy the entire archive folder to the appropriate location. When you copy archives from another computer, only the owner has read/write permissions on the archive folder. Group users and other users do not have any permission on the files and folders. To be able to view events from archives copied from another computer, you must grant read permissions to group and other users. To grant appropriate permissions, you must do the following:

• Change the permissions on the files in the destination archive folder from 600 to 644.
• All folders under the /eventarchive partition should have permissions 755 or (drwxr-s).
• You must also change the ownership of the folder to sesuser.

Exact steps to perform :

To restore archives from another computer

1. Copy the archive folder that you want to the /eventarchive partition into its appropriate location (archive path).
2. All folders under the eventarchive partition should have the owner and group as sesuser:ses.

Run the following commands to change the ownership of the folders:

cd /eventarchive

chown -R sesuser:ses default

chown -R sesuser:ses ssimlogs

1. All folders under the eventarchive partition should have permissions 755 or (drwxr-sr-x). You must change the permissions on the folders to 755 as shown in the following example:

cd /eventarchive

chmod /R 755 default

chmod /R 755 ssimlogs

1. All the files in the archive folders must have the permissions as 644 (-rw-r--r--).

You must change the permissions on all the files in the archive folders to 644 as given in the following example:

chmod 644 /eventarchive/default/2009/08/01/1249139954617.edx

or you can try running the same command for *.edx files.

Note: You must change the permissions for all the files in the folder.

That's it you are now ready to use restored Event archieve data!!
