Can I safely perform full backups without breaking log shipping? Can I do point in time restores if

Posted By:      Posted Date: August 28, 2010    Points: 0   Category :Sql Server
I'm building a system using SQL Server 2008. I have log shipping set up across our WAN, and that's working fine. I need to perform local backups on the primary server so that I'm not relying on the (slow) WAN if it needs to be recovered from a server crash. Ideally, it would be nice to be able to perform point in time restores. I understand that I can use the transaction log backups, created for log shipping, to restore from. But I still need a full backup to start the restore from - and there seems to be some confusion regarding whether or not performing a regular full backup on the primary server will affect log shipping. Even on these forums, conflicting advice has been given, with some people saying it's fine as long as you don't do transaction log backups, and others saying you must run COPY ONLY backups (though they were talking about Server 2005). From what I understand, you can't do point in time if you use copy-only backups. I'm getting the impression that this used to be a problem under 2005, but under 2008 you can safely perform full backups while log shipping is running. Can anyone confirm my understanding before I make a career-altering error? :)

SQL Server 2005 Log Shipping and subsequent FULL backups that are needed

Afternoon,   I have a few Log Shipped DBs that are working great.   Currently they are set to fire off every 15 minutes 24/7.   My question is this ... I need to get FULL backups of the source DBs in order to restore them on certain Dev boxes.   If I were to execute the full backup on one of these Log Shipped DBs ... how would it affect the log shipping process?   Is there a special method to accomplish this?   As a side note, what would be some concerns/issues if in being able to create the FULL backups and not interupt log shipping, I were to create the backup using a 3rd party tool like Quest LiteSpeed?   I sure wish we were on Enterprise, then I could create a mirror and then snapshot off it to create my backups BUT ... that is not the case as we stand today.   Thanks

Log Shipping and Full Backups

Do I need to stop/disable the Log Shipping Jobs on Source/Desitnation instances when I create full or incremental backups?  Or can these jobs just continue on their schedule while the full backup or incremental backup is running?  My customer is using SQL Server 2005 Standard edition and is using log shipping to a warm standby server. 

Point In Time Recovery of Database with Full-Text Search enabled SQL 2005


Is this possible? 



Backup made at 10:30

changes made in system

Tail of the log backup taken at 10:35

Restore to point in tim 10:33 

At this point I get the error System.data.sqlclient.sqlerror: The File "sysft_yadayada_1" was not fully restored by a database or file restore.  The entire file must be successfully restored before applying this backup set.

BUT when I restore the database to most recent possible I have no issues..

when I do a select * from sys.master_files    sysft_yadayada_1 does not exist in that list, but  sysft_yadayada_5 does... When we were initially configuring fulltext search for this application we had a couple hiccups first till we got it working and thats the filename that ended up sticking.

how to understand full recovery model can restore to the point of failure


if I backup log hourly, 50 minutes after last log backup, sql server corrupts, I guess I can only restore to the last tlog backup, how to understand restore to the point of failure?

also if I use simple recovery model, backup differentially every hour, do I have the same data protection? I know answer is no, but how to understand it?



Workflow or Time Job for email reminder on Tasks List in Share Point 2007

Also if the due date gets change it should change the reminder accordingly.

Which approach i should take to achieve this?? 




point in time restoration



 I have question on this backup\recovery.Let's assume there is a disaster at 6:14 pm and our recovery model is full and we take Full back up's at 12:00 am and differential's at 6 hrs interval and transactional one's for every 5 mins. So, in this case to recover the db, we apply our FB(12:00)+Differential(6:00pm) + Transacational log 1(6:05)+transactional log(6:10) . We need to backup the tail to get the point in time restoration. Could any one tell when shall we  backup the tail log?

is it before doing the restoration??


AGGREGATE over a time period: how to behave like a distinct count ? (aggregate on the full period an


I would like to compute a measure "MyMeasure" over the last 12 months :

Aggregate({[Event DATE].[Calendar].CurrentMember.Lag(11):[Event DATE].[Calendar].CurrentMember},[Measures].[MyMeasure])

MyMeasure is not a distinct count, so the results returned is the SUM of the distinct count performed on each month over the last 12 month.

What I would like to have is the distinct count over a full year (all months taken together).

For example, suppose that MyMeasure is a simple measure that always returns 1.

The aggregation returns 12 (1 for each month then SUM). I would like it to return 1 (measure on the whole period).

Can somebody help me that's really a very big issue I have to fix !


When to perform a full crawl?

One of my coworkers told me we must do a full crawl every couple weeks to remove deleted content from the index. He claims deleted pages aren't removed from the search results until a full crawl is ran. This doesn't make any sense at all since I see removal warnings in the crawl log all the time. This blog post doesn't mention it as a reason to do full crawling either. Does what my coworker said make any sense?

Round off time to the nearest minute

How would you round this up to the nearest minute? There isn't a built in function to do this so you have to use a little bit of maths to get there. There are 60 seconds in a minute. We already have 38 seconds on the clock. So we need to add on 60 - 38 = 22 more seconds.

Performance Tests: Precise Run Time Measurements with System.Diagnostics.Stopwatch

Everybody who does performance optimization stumbles sooner or later over the Stopwatch class in the System.Diagnostics namespace. And everybody has noticed that the measurements of the same function on the same computer can differ 25% -30% in run time. This article shows how single threaded test programs must be designed to get an accuracy of 0.1% - 0.2% out of the Stopwatch class. With this accuracy, algorithms can be tested and compared.

Date and Time Functions in SQLSERVER

Date and time functions allow you to manipulate columns and variables with DATETIME and SMALLDATETIME data types.

1 DATEPART Function
2 DATENAME Function
3 DAY, MONTH, and YEAR Functions
5 DATEADD Functions
6 DATEDIFF Function
7 More SQL Server Functions

Data Types - Date and Time in SqlServer

Date and time values can be stored with either the DATETIME or SMALLDATETIME data type. The difference between the two is that SMALLDATETIME supports a smaller range of dates and does not give the same level of precision when accounting for time. The DATETIME data type can hold values from January 1st of 1753 to December 31st of 9999. The time is stored to the 1 three hundredths of a second and each value takes up 8 bytes of storage. The SMALLDATETIME data type can hold values between January 1st 1900 and June 6th of 2079. The time is tracked to the minute and each value takes up 4 bytes of storage. The majority of business applications can live happily with SMALLDATETIME, however, if you are in an environment where each second matters or you need to make estimates to the distant future (or past) then you have to resort to DATETIME. If you fail to specify the time when inserting a value into a DATETIME or SMALLDATETIME column, a default of midnight is used. If you fail to specify the date portion the default of January 1, 1900 is used.

Using JQuery to perform Ajax calls in ASP.NET MVC

The muscle behind the actual asynchronous calls comes from JavaScript. I looked around at a bunch of existing JavaScript libraries and settled on JQuery because of the way it leverages existing CSS knowledge. The three things that the library should do easily are:

.NET 4 Web Application Startup Time

I was chatting with Jonathan Hawkins and some of the folks on the ASP.NET team about performance and Jonathan mentioned the startup time for large ASP.NET applications is improved on .NET 4. There are some improvements in the CLR and in ASP.NET itself that helped. If you have a giant app, you should do some tests.
