Back up content data

User Role: Administrator

To ensure that you always have up-to-date copies of the data that the IDOL Server stores, we recommend that you back up the IDOL Server at regular intervals. This section describes two methods to back up and restore content data:

Enabling scheduled backup

To enable scheduled backup, follow these steps:

1. Open the <Smart Analytics Installation>\Content<x>\Content<x>.cfg files of the content servers.

2. Locate the [schedule] section. Insert the following lines, and then update the values if needed.

   [Schedule]
   Backup=true
   BackupTime=10:50
   //0 means daily backups
   BackupInterval=0
   BackupRetryAttempts=3   
   BackupRetryPause=5
     
   NumberOfBackups=7
   BackupDir0=C:\idolbak\content1\Backup0
   BackupDir1=C:\idolbak\content1\Backup1
   BackupDir2=C:\idolbak\content1\Backup2
   BackupDir3=C:\idolbak\content1\Backup3
   BackupDir4=C:\idolbak\content1\Backup4
   BackupDir5=C:\idolbak\content1\Backup5
   BackupDir6=C:\idolbak\content1\Backup6
   

   Parameter	Description
   BackupInterval	The interval that the system creates backup files. If you set the value of this parameter to 0, the system will automatically create a backup every 24 hours.
   BackupRetryAttempts	The number of retry attempts when a backup task fails.
   BackupRetryPause	The interval (seconds) between retry attempts when a backup task fails.
   NumberOfBackups	The number of backup files that are created by the system. If you set the value of this parameter to 7, the first 7 backup schedules create new backup files respectively. The eighth backup operation overwrites the first backup, the nineth backup operation overwrites the second backup, and so on.

3. Restart the content servers.

After you enable scheduled backup, the system automatically creates a series of backup files for the content server. See the following screenshot as an example:

Using commands

To back up content data, you can export all contents index and category files with commands. To do this, run the following actions by using the Smart Analytics Assistant (SAA) utility:

To export contents index:

http://<idolhost>:<MainIDOLServerIndexPort>/DREEXPORTIDX?filename=c:\BackupFolderName\File&HostDetails=true

To export category files:

To restore the content data backed up using this method, you can run the following action by using Smart Analytics Assistant (SAA) utility:

http://<idolhost>:<ACIPort>/DREADD?/<path>/<xxx.idx.gz>&CreateDatabase=True

For example:

http://<idolhost>:<Content1indexport>/DREADD?/home/Jora/BackupFolderName/FilePrefix-SGDLITVM0772-10010-0.idx.gz&CreateDatabase=True

http://<idolhost>:<Level2proxyindexport>/DREADD?/home/Jora/BackupFolderName/FilePrefix-SGDLITVM0772-30010-0.idx.gz&CreateDatabase=True

http://<idolhost>:<Level2proxyindexport>/DREADD?/home/Jora/BackupFolderName/FilePrefix-SGDLITVM0772-30020-0.idx.gz&CreateDatabase=True
