Once upon a time, somewhere in a dark, lonely data center room, 2 AM. We're sleeping well and our mobile is ringing and ringing. Message: DISASTER! In this session (on slides) we are NOT talking about the potential disaster (such BCM); we talk about: What happened NOW? Which tasks should have been finished BEFORE. Does virtual or physical SQL Server matter? We talk about systems, databases, people, encryption, passwords, certificates and users. In this session (on few demos) I'll show which part of our SQL Server environment are critical and how to be prepared for disaster. In some documents, I'll show You how to be BEST prepared.

4. 2:00 am … in a dreams…
▪ Your best time for dreaming … is the best time for Disaster
▪ Your mobile phone ringing and ringing…
▪ And Your husband / wife say…….
5. 2:15 am … in a car
▪ What’s happen with my server?
▪ When I made last backup?
▪ Where is my backup?
▪ Have I ever tried to restore?
▪ If yes – I hope that all in a team (about team soon) remember about (me?)
▪ If not – who can help me NOW?
6. 2:40 am … in a server room
▪ $#$$@$^^#^&^@!#
▪ Is Windows Server alive?
▪ YES (thanks all saints)
▪ or NOT (damn)
▪ who is responsible for it?
▪ Is my SQL Server alive?
▪ YES (why phones ringing)
▪ or NOT (…)

implementation

or included during backup tasks (include / exclude list)

12. backup (registry) > extract from sop*

13. SQL Server Backup Best Practices |
Posted on October 17, 2007 by Brent Ozar in SQL Server
> http://bit.ly/12oXm4h
• Never back up databases to local disk.
• Back up databases to a fileshare, then back the share up to tape.
• Cost justify the network share with lower licensing costs & simpler backups.
• Back up to a different SAN if possible.
• My sweet spot for the backup array is raid 10 SATA.
• Backup agents like NetBackup and Backup Exec mean giving up scheduling control.
• Do regular fire drill rebuilds and restores.
• Build a standalone restore testbed.
• Keep management informed on restore time estimates.
• Trust no one.

Restore (sql databases)
▪ about type of backup ( simple rm / full rm)
▪ about place for stored backup data
▪ about the procedures of recovery
▪ about estimated time for recovery
▪ about REAL TIME for recovery
▪ about tools for recovery
▪ about Corporate Backup Manager
▪ about password for access to library

▪ the date of commencement and completion of the recovery test
▪ client for which the test was performed recovery test
▪ servers involved in testing and replacement
▪ extent of testing and replacement
▪ person / persons performing the recovery test
▪ person on the client side accepts the correctness of the recovery test
▪ subsequent to the recovery test

Performance best practices for SharePoint backup and restore operations
▪ Minimize latency between SQL Server and the backup location
▪ Avoid processing conflicts
▪ Keep databases small for faster recovery times
▪ Use incremental backups for large databases
▪ Use compression during backup
▪ Use RAID 10 if you use RAID

Configure SharePoint settings to improve backup or restore performance
▪ You can only configure file compression and log file settings in Windows PowerShell.
▪ If you use the Export-SPWeb Windows PowerShell cmdlet, you can use the
NoFileCompression parameter.
▪ When you use the Backup-SPFarm cmdlet, you can also use the BackupThreads parameter to
specify how many threads SharePoint 2013 will use during the backup process.
Consider site collection size when you determine the tools to use
▪ Up to15 GB
▪ Use the Backup-SPSite Windows PowerShell cmdlet. For more information, see Back up site
collections in SharePoint 2013.
▪ 15-100 GB
▪ Use a SharePoint 2013 tool, a SQL Server tool, or other database backup tool to protect the
content database that contains the site collection.
▪ Over 100 GB
▪ Use a differential backup solution, such as SQL Server 2008 R2 with SP1 or System Center
2012 - Data Pro

Backup & Restore (sharepoint farm)
• Quality assurance best practices to back up a SharePoint farm
• Ensure you have enough storage space
• Routinely test backup quality
• Back up ULS trace logs
• Store a copy of backup files off-site
• Procedural best practices to back up and restore SharePoint 2013
• Use FQDN server names
• Keep accurate records
• Have a recovery environment ready
• Schedule backup operations
• Use the SQL FILESTREAM provider with BLOB storage

Procedures
▪ It is not about stored procedures!!!
▪ It’s about storing procedures with answers for the following:
▪ One piece of paper
▪ How to start restore
▪ Who can help
▪ How to processing a restore
▪ When we can finish
▪ It MUST be simple

PSO > USO > SLA
▪ PSO Planned System Outages – Planned System Unavailability
▪ Minimum planned unavailability, due to the need to carry out modernization work, installing
patches, replacement / extension of hardware,
▪ Agreed/accepted by/with the client and not affecting the provisions of the HA, and SLA, until
▪ ...USO Unplaned System Outages – Unplanned System Unavailability
▪ an error that prevents a partial or total work environment in a tangible, measurable customer
▪ resulting in high costs if you need repairs, as well as penalty payments for non-SLA
