Technical Brief
Backups and Repository Maintenance
Overview
Persystent Suite is comprised of various server based components. The purpose of this document is to define what site specific data that should be backed up and the procedures for properly backing up Persystent Suite servers. This document also covers the procedures used to clean up unused files in the shared repository.

Shared Repository Maintenance Procedures
Backing Up the Persystent SQL Database
Requirements
Microsoft SQL Server 2005 or later with Management Studio
Additional information
Persystent Suite utilizes a SQL database called PTC_SITE. This database should be backed up in accordance with your existing SQL backup software procedures. If Persystent Suite is the only SQL Database in your environment, then Persystent recommends to backup the PTC_SITE database using the internal SQL backup function.
Backups can be configured with SQL built in backup functions or using a third party SQL backup agent (i.e. Symantec Backup Exec SQL backup agent). This document outlines the basic backup functions provided within the SQL application. Consult your backup vendor’s documentation for SQL agent backup procedures.

Procedure Overview
The example in this document will concentrate on using the SQL 2005 Management Studio when backing up the database. The procedure to configure Microsoft SQL Server 2005 backups is as follows:
Use the Maintenance Wizard to define and schedule the backup job.
If not using SQL 2005 or you utilize a third party SQL backup agent like Symantec Backup Exec, please contact your backup administrator for further assistance.
To Backup Microsoft SQL 2005 Database
1. SQL 2005 provides the administrator with a maintenance plan wizard which steps through the process of creating a backup job and schedule. Run the Maintenance Wizard by right-clicking on
3 2. Click the Next button to start the Wizard.
4 4. Then click on the Change button to edit the schedule for the plan. Schedule the backup for
5 5. Select the specific tasks to perform. In this step, select Backup Database (Full) task. Click Next.
6 7. Select the Specific Database PTC_SITE in the dropdown menu.
7 9. Select the report options desired. Click Next.
10. Complete the Wizard. Click Finish.
11. Ensure that the file location that the SQL database backups reside in are being backed up by your backup administrator.

Backing Up Shared Repository, Images, and Host
Information
Requirements
Due to the high volume of read/write transactions in the Persystent shared repository, it is recommended that all Persystent server services should be stopped when backing up the repository and host information.
Additional Information
The following is a list of directories used in the Persystent Suite installation and what information is stored in each of these directories.
Program Files\Persystent\Repository\shared – location of all shared files. This will be thelargest directory in your repository.
Program Files\Persystent\Repository\global\hdimages – location of all base imagepointer files.
Program Files\Persystent\Repository\global\packages – location of all software packagesand pointer files.
Program Files\Persystent\Repository\global\hosts – location of all unique host image pointerfiles, boot logs, and heal logs.
Procedure Overview
The procedure to backup the shared repository including base images, client repair points, and backed up profiles is as follows:
Stop all Persystent services on the server.
Copy the following folders to an alternate location on a network or another drive.
Restart all Persystent services.
Backup the copied files using desired backup application.
To Backup the Persystent Shared Repository
1. The stopping and starting of services and file copy process can be accomplished using a simple batch file. This example assumes that the D: drive is the location of the Persystent Server and Repository, and the Q: drive is the destination of the backup.

2. The files copied to the Q: drive should be backed up utilizing the existing backup solution.
Backing Up Images to a RAD file
Requirements
Adequate disk space for RAD file to be created. Base Images created on Persystent server.
10
Procedure Overview
Backing up images to a RAD file will allow all Base images to be placed in a single instance storage flat file. This can be useful for backup purposes as well as allowing these images to be imported into other Persystent Suite repository servers.
The procedure to create a RAD file backup is as follows:
On the Persystent repository server, open the Persystent Server Utility. Select the images to export.
Select the location to create the RAD file. Export the image to the desired location.
To Perform Repository Maintenance
1. Log into the Persystent server. Go to Start | All Programs | Persystent | Persystent
Server Utility.
2. Click the Export tab and then select the images that should be included in the RAD file. 3. Enter a name and location for the RAD file.
4. Click Export. The progress bar will display; the OK button will activate when completed.
Shared Repository Maintenance Procedures
Requirements
All Persystent Server services should be stopped when performing repository maintenance.
There should be enough disk space to allow the repository services to re-index the files. A good rule of thumb is at least 30% free space on the repository drive.
Example: 100GB repository should have at least 30GB free for the procedure.
Procedure Overview
The maintenance routines can take between 15 minutes and 4 hours to complete based on the size of the shared file repository server, disk speed, and server specifications. Persystent recommends scheduling this routine during non-peak business hours.
The imaging capability and client/server communications will be down during the maintenance window. Client computers however will continue to function normally during the maintenance period. Persystent recommends monthly repository maintenance to ensure optimal performance of the shared repository.
The statshared command will mark all files that are currently in use in the repository. The sweepshared command will purge inactive files from the shared repository, freeing up disk space.
11 The procedure to perform repository maintenance is as follows:
Stop all Persystent services.
Execute the statshared and sweepshared repository utilities.
(Optional) Run Disk defragmentation utility if the repository resides on a local disk. If the repository is on SAN storage, the SAN administrator should be responsible for disk maintenance procedures.
Restart all Persystent services.
To Perform Repository Maintenance
1. The stopping and starting of services and repository cleanup process can be accomplished using a simple batch file. This example assumes that the D: drive is the location of the Persystent Server and Repository.
