The document outlines best practices for disaster preparedness, particularly focusing on backup and recovery strategies for SQL databases and other systems. Key recommendations include regular backups, testing recovery procedures, ensuring clear communication regarding disaster roles, and maintaining up-to-date hardware and software inventories. The overarching theme emphasizes the importance of being prepared and minimizing potential downtime during disasters.

• 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 (…)
− why I’m responsible for it?

Backups (sql databases)
• about type of backup ( simple rm / full rm)
• about place for stored backup data
• about backup window
• about procedure used for backup
• about backup tools
• about backup of „backup logs”
• about estimated time for executing backup
• about REAL TIME of executing backup

11. backup > extract from sop*
In the request, backup, should include the following information:
• Information about the operating system and application version for online
backup and installed updates for these components a file backup policy, in particular:
− a number of versions of a file stored
− the storage time of the next version of the file
− the frequency of execution of such incremental backups with the proposal of their
implementation
• Online Backup Policy
− the storage time of a full backup with storage time such an incremental backup
− the time of transaction log files
− the frequency of execution of a full backup with the proposal deadline for
its implementation
− the frequency of execution of the transaction log backup
• Information about trees directories / files that should be omitted
or included during backup tasks (include / exclude list)
• Number and type / model of physical processors,
• Does the node will use the connection to the SAN to implement backup

12. backup (registry) > extract from sop*
This register contains information about a backup plan implemented.
Backup file space:
− number of versions of a file stored in a backup
− number of days that are kept more versions of a file
− number of versions of a file stored in the backup system after its removal from
client device
− number of days that will store the latest version of the deleted file from the client
device
− number of days that will be stored in the archive
The list of nodes defined in the system backup:
− Domain | Node name | IP address of the node
− The list of defined backup tasks (called schedule)
− name of the task (schedule) | execution time
− a period of at which the task is repeated

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

Registery for Recovery/Restore/Replacement Tests
This register contains information about the tests and replacement of part or all of the
environment. It consists of the following fields:
• 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
• people 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

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

➢ Backup&Restore for sql (and know-how about stored place, and restoring way)
➢ Backup&Restore for sp (tools, size, performance, site collection size, compression )
➢ Procedures (the short is better | one page is the best)
➢ Roles (who can help, who is necessary for access)
➢ SLA (90? 95? 99,99? in minutes, hours or days you have to recover)
➢ Envelope (with user names and passwords for all important accounts)
➢ Hardware (server, motherboard, CPU, RAM, LAN, HDD, SDD, USB)
➢ Support (maintenance contract, scope, contacts, responsibility)
➢ Software (Windows+SQLServer+SharePoint and SP+CU)
➢ Keys (serial numbers, physical keys, knife)
➢ Encryption (arrghhhhh!!! Certificates, keys, internal/external)
➢ Team (member, leader, samurai…)
