Does an Differential Backup contain all the changes since the last full backup, including Inserts, Updates, and Deletions. Our DB has "Truncate on Checkpoint" = True, so Log backups are non-sensical. I want to apply the Differentials to an archive, offline DB.
"one pebble does not fill the void, but it is a start."
"Dedicated to only creating original mistakes."
If my backup starts at 8PM and take 1 hour to complete, will the changes made to the database during that hour be captured in the full backup?
Stated another way, will my backup be a snapshot of:
a) 8PM when the backup started
b) 8PM with some of the changes made between the hour
c) 9PM when the backup finished?
Anybody know the exact way SQL Server handles that logic?
Thanks,

My Question is of understanding Incremental Backup. How does this work,
Does it go by new files added or activate on file size.
Hi,
I am working on one application, which retrieves data from multiple tables in the database and all the fields retrieved, are exported as an excel sheet. All the export functionality is done through DTS. And the data is retrieved using an SP.
I am supposed to use an "incremental backup" approach here. Means, for the 1st scheduling of the package, all the database dump will be there in excel file. But, after that only fields that are updated/inserted are to be filled in the excel file. Each time, when the dump of the database is taken, the excel file is stored in an archive folder with Date and tiemstamp(e.g. TEST_11_04_2007_15_00_00.xls)
e.g. For the first dump, I get 100 records from the database. Before next execution of the package, 10 rows get inserted and 1 row gets updated. So, on the second time execution of the package, I should populate the excel sheet with those 11 rows only, and not 110 records.
I am not authorised to change the database schema.
So, is there any approach to try out this?
1) We are doing Weekly Full & DAILY night incremental backup of TL using Veritas Backup Manager to Tape.
One day I took Incremental Backup of TL file manually using studio and deleted the backup file.
Will I able to restore completed if something happens on next day ? Is automated backup takes care of Incremental backup from last night instead of manual interim backup ?
What is the recommendation ? If automated backup is enabled, we should not do manual backup ?
2) In Full Recovery Modek , If I do full backup , Does it backup Transactional Log also or only Datafiles ?
Thanks

View 2 Replies View Relatedhi, I would like to know the correct reaction for a crash in both senarios.
First senario,
I made a full back up at 6 am , then scheduled sql server to make transaction log back up every 2 hours (8,10,12,2 pm,4,6,8) . If I have a crash at 12:30. How would I resotre the data in the first senario....Can I restore the full back up done at 6 am then restore the last transaction log backup ( which is 12 Noon ) . I am not sure If I need to resotre the whole tran from 6 am till the time it was crashed.
Second senario,
I made a full back up at 6 am, then scheduled sql server to make Incremental backup every 2 hours (8,10,12,2 pm,4,6,8) . If I have a crash at 3:00 pm. How would I resotre the data in the second senario. ....Do I restore the full backup at 6 am then restore each incremental backup backwords ( 2,12,10,8)
AS you can see, I am not sure how to deal with this issue, I do appreciate your feedback.

In MS SQL 2005 when you do a Full Backup does it also backup andtruncate the transaction logs or do I need to back the transactionlogs up separately?Thanks.Brian
View 4 Replies View RelatedQuick question about deleting data from SQL Server.We have a table that gets quite a bit of activity with an attribute oftype text (inserts that store new text entries of 50-200k apiece).Older rows aren't needed so we have a process that deletes rows morethan 30 days old (using delete statements).When these rows are deleted, is the memory consumed by theseautomatically recovered? Or is there some process that must beperformed to recover the space? What about the transaction log? Doesthat grow with each deletion? When do transaction logs get reset?Thanks,John
View 2 Replies View RelatedGuys, could anyone tell me if MSSQL Server 7 has 'on delete cascade' option when creating a foreign key constraint or something similar to it. I'd really like MSSQL to remove all dependent records (child records) automatically from one table when I'm deleting a parent record from another record. I know that I can do it via trigger, but the FK constraint should be removed or disabled. I would really appreciate your help. Thank you very much.

View 4 Replies View RelatedI wanted to know if SQL Server 2000 does something behind the scenes in a transparent manner whenever records are inserted/deleted from two tables between which a join is defined based on a primary key to foreign key relationship. So I have already defined a parent-child relationship through the 'Database Diagram' between these 2 tables. I know when a table is indexed then SQL Server will perform some actions behind the scenes in a transparent manner.The reason I am asking this question is to know if its bad to define parent-child relatioship between 2 tables that will each contain thousands or millions of records.

Hi!
I have a request of having a select statement displaying a list of values in descending order and another column that tells what record it is.
something like this:
id | value | no
4 345 1
7 234 2
2 143 3
9 32 4
3 4 5
...
is this possible?
can it be something like this:
select id, value, increment(1,1) as no from tblTable
order by value desc
thanks.
I am looking to create a incremental value based on the resulting insert that I am using. There already is another field being used as an identity field. I have a beginning value that I just want to add the row number to for the insert.
insert into lineitem select substring(group_id,4,len(ltrim(rtrim(group_id)))-3) as co_code,
0,0,(case when enddate < cast(month(getdate()) as varchar(10))+cast(day(getdate()) as varchar(10))
then 'Prior' else 'Current' end ),
left(acct_type,2) as bene_type, convert(smalldatetime,left(ltrim(rtrim(eff_date)), 8)),
0,trans_amt,0,0,convert(smalldatetime,left(ltrim(r trim(sett_date)),8)),
ltrim(rtrim(b.fname)) + ' ' + ltrim(rtrim(b.lname)) as payee,0,0,a.ssn,'Y',999+count(*),
(case when isnull(b.location,'') = '' then '' else b.location end) as location
from mbi_tran_temp a
left join enrollees b on a.ssn = b.ssn and
ltrim(rtrim(a.group_id)) = ltrim(rtrim(b.mbicode))
The '999+count(*)' is where I would like to have the incremental value.
Hi,
Is there any way to maintain history of data while incremental load without using the Slowly changing dimension(SCD) concept?
Hi Friends please let me know how can we incrementally load a destination table with source table. bearing in mind that we need to track that there are no duplicates in the destination table. I need to load only changed or new data in the final load. Please give me some examples also. I am tryin this from last 2 days as I am totally new to SSIS.

Hi All
I've created an SSIS package that loads data from source to destination, using Lookup and conditional Split to check New rows and changed rows for one table.
Now I want to take this father by loading data for multible table more that 100. I did it in T-SQL using dynamic sql and cursor.
How can I achive this using SSIS.
I was wondering if there is a way to schedule a tast that will dump afixed width text file of all the new entries in a table. So if I hada table with likeusername - varchar(20)created - smalldatetimeI could get a weekly feed each week of all the new users in a textfile. I know I could write a script that would go through and do thisby looking at the time stamp, and the last time that the filepreviously ran and get the new dates but I was hoping there was abuilt way to do this. Or perhaps a more elegant solution.Thanks,Charlie

I am attempting to perform an incremental load, inserting new rows and updating existing rows. I am using a lookup and everything works fine, except when it is the first load of the destination table. As there are no records in the table at all, the lookup fails. I thought of using a rowcount - if the count variable is zero load everything from temporary table to load table, otherwise perform lookup and incremental load.
Can anyone help?
We are in the process of converting our existing incremental loads from DTS to SSIS.
Currently we get all the data for the past month into temp tables in the warehouse, compare with key fields add the new rows and update changed rows. All this is done using Execute SQL task.
Is there a better way to implement the incremental logic using SSIS any new objects that be used to avoid too much SQL codes? Performance is very important and we do a lot of aggregation after the load for the reports to run faster so that we can meet customer SLA's.
We have around 20 tables that needs to be loaded 4 have large amount of data between 20 and 40 million rows out of which we will be brining over around 100 thousand during each incremental run. The other tables have less than 100,000 rows so does not hurt truncating and reloading the entire table.
Any assistance is appreciated.
Thanks!
Hi everyone. I'm trying to figure out how to run an incremental load into a Staging table.
At this point I'm not trying to Conditional Split it between "New" and "Changed" records... just the load.
The logic in my head says that after each load, you can take the most recent "modified" date/time and store that in an incremental load table. That way, next time you run an incremental load, you just have to look up that "modified" date/time, and only load the source records with a "modified" date/time later than the record in your incremental load table. Does that plan sound feasible?
I think so far my problem is that my source is on an ADO.NET connection, and my incremental load table is on my SQL Server. So when I do my load from the ADO.NET database, I cannot read the data from the incremental load table.
Is my logic flawed?
Any help would be appreciated.
Thank you very much!
i have to import a csv file into a database via ssis and so far everything works fine. but now i have to add a column where a incremental int should be inserted, so every row should have a unique number ... i tried to realize this by using derived col transofrmation, but without success ... has someone an idea how to do this?
