- Best practices for backup and restoration
- Best practices for minimizing the impact of a disaster
Best Practices for Backup and Restoration
To facilitate your back up and restoration process, apply the following best practices when you back up or restore your data:
- Perform regular backups at appropriate intervals. The simplest
and most commonly used backup type and rotation schedule is a full,
nightly backup of the entire SQL Server database. Then, if
restoration is necessary, the restoration process requires only one
backup and no more than a day’s data should be lost.
- If you use cmdlets or the Lync Server Control Panel to make
configuration changes, use the Export-CsConfiguration cmdlet
to take a snapshot backup of the topology configuration file
(Xds.mdf) after you make the changes so that you won't lose the
changes if you need to restore your databases.
- Ensure that the shared folder you plan to use for backing up
Lync Server 2010 has sufficient disk space to hold all the backed
- Schedule backups when Lync Server usage typically is low to
improve server performance and the user experience.
- Ensure that the location where you back up data is secure.
- Keep the backup files where they are available in case you need
to restore the data.
- Plan for and schedule periodic testing of the restoration
processes supported by your organization.
- Validate your backup and restoration processes in advance to
ensure that they work as expected.
Best Practices for Minimizing the Impact of a Disaster
The best strategy for dealing with disastrous service interruptions (caused by unmanageable events such as power outages or sudden hardware failures) is to assume they will happen and plan accordingly. The disaster management plans you develop as part of your backup and restoration strategy should include the following:
- Keeping your software media and your software and firmware
updates readily available.
- Maintaining hardware and software records.
- Backing up your data regularly and ensuring the integrity of
- Training your staff in disaster recovery, documenting
procedures, and implementing disaster recovery simulation
- Keeping spare hardware available or, if you have a service
level agreement (SLA), contracting with hardware vendors and
suppliers for prompt replacements.
- Separating the location of your transaction log files (.ldf
files) and database files (.mdf files).
