As I tested, I found with Transaction logs and Full Backup can support any changing of database.
So I doubt that Do I need to back up by diffrential style ?
Please suggest me.
Hi Expets!!!!!!!!
I did full back up and restore it. I didn't face any problem while restoring it. After that, I did differential back up. And now trying to restore it. I saw name of all the files at the time of full back up. It were something like ABC.MDF, ABC1.NDF,ABC2.NDF,ABC3.NDF,ABC4.NDF,ABC5.NDF, ABC_log.LDF, ABC_log2.LDF. But now, when I am trying to restore differential back up, I am getting different names, such as, ABC.MDF, ABC2.NDF,ABC3.NDF,ABC4.NDF,ABC5.NDF, ABC6.NDF,ABC_log.LDF, ABC_log2.LDF.It means that, ABC1.NDF file is missing and this time I am getting ABC6.NDF as a extra file. But total number of files are same. How is it possible? I checked, in the original database, there names of the files math exactly with what I am getting in differential back up file. Now I am getting one error message while trying to do differential back up. Any idea what is going on and how to solve this problem? The error message is as follows:-

Hello,I'm trying to create a simple back up in the SQL Maintenance Plan that willmake a single back up copy of all database every night at 10 pm. I'd likethe previous nights file to be overwritten, so there will be only a singleback up file for each database (tape back up runs every night, so each daysback up will be saved on tape).Every night the maintenance plan makes a back up of all the databases to anew file with a datetime stamp, meaning the previous nights file stillexists. Even when I check "Remove files older than 22 hours" the previousnights file still exists. Is there any way to create a back up file withoutthe date time stamp so it overwrites the previous nights file?Thanks!Rick
View 5 Replies View RelatedNew to Database Mirroring and I have a question about the Principal database server. I have a Database Mirroring setup configured for High-safety with automatic fail over mode using a witness.
When a fail over occurs because of a lost of communication between the principal and mirror, the mirror server takes on theĀ roll of Principal. When communication is returned to the Principal server, at some point does the database that was the previous Principal database automatically go back to being the Principal server?

View 2 Replies View RelatedDoes anybody know of a way to rollback SQL Server 2005
databases back to SQL Server 2000? Is there a way of doing it without
resorting to Copy Database Wizard? I love to find a way of attaching a SS 2005 database
to a SS 2000 instance without any issues.
I recently upgraded to SS 2005 and I am very unhappy with the SS 2005 and I
want to rollback to SS 2000, which was a lot more stable. I am having
several major issues that are affecting my whole company's day-to-day
operations and the managers are not happy. Some of the issues include
night time batch running very sluggish for no apparent reason. This is a
biggest problem because it only occurs once or so a week and causes a disturbance
with the daily activities when the night time processing isnt completed on
time. The rest of the time, the batch processing runs great, even a little better then on SS 2000. I
don't believe it is a matter of my application needing to be retuned because if
that was the case, then why isn't it running sluggish every night? Also,
it's never the same day that the sluggish behavior occurs. If it was occurring
on the same night, then I would have something to investigate within our
application, but it doesn't. Another issue that I am having involves a
night time job that restores a copy of the production database to the Data
Warehouse server to be used for updating the data warehouse. Again, most
of the time it runs great (~2 1/2 hours), but once or twice a week, it goes
stupid and takes 6 1/2 hours for no apparent reason. Again, it is not happening
the same day either, which could give me something to invesigate. On SS 2000, this same job ran flawlessly. Never I did I run into situation that the
database restoration took that long to run. Even another issue involves a SQL Server Agent Job that was put into suspended
state. What's a suspended state and how can I get it out of suspended
state? I can find no information about suspended state in BOL. I
did a Google and nothing came up. If this suspended state was put
in for security reasons, great, but then tell me how I can remove the suspended
state. I am also not happy with the
fact that I can't get accurate information about the queries that are actively
running at that particular moment. In SS 2000, when I noticed high CPU
usage on the server, I would run the sp_who2 active stored proc and it would
show me all the active thread and how much CPU it was consuming. I would
then find the running threads with the highest CPU numbers and investigate the
query and see if we could improve it. Now in SS 2005, I get in the same
situation and run the sp_who2 stored proc, and there is no smoking gun.
All of the active threads are showing very little CPU usage, which I am very
suspect of. What the heck happen to sp_who2? I looked at some of
the other ways of looking at running processes (i.e... sys.sysprocesses) and
they don't appear to be giving the information that I need.
I am very unhappy and I just want to roll back to SS 2000 and wait a couple of
years before I upgrade to SS 2005.

I know that the differential backup will only back up information that was changed since the last full database backup, but I have process that I need to implement and need to know if differentials will work.
1. Perform full database backup on Sunday.
2. Perform differential backups Monday thru Friday (twice a day).
3. Perform a database restore on the following Sunday from the backup taken on the previous Sunday.
4. Perform differential backups Monday thru Friday.
At this point I would repeat steps 3 and 4 for the following weeks.
My question is this. Since I didn't actually perform a backup in step 3, but instead performed a database restore, will the differential backup in step 4 backup all of the information changed since step 1??..or will it backup all of the information changed since the restore in step 3? I'm hoping it will only back up the information changed since step 3.
Thanks!
I perform a full database backup at night with a differential backup at noon each day. I created 2 devices to do this. Northwind (for full backups) and northwind_diff (for diff backups).
When the differential is run, it appends each day's noon backup to the northwind_diff file so the file doesn't really reflect only changes - it just keeps growing and growing. I'm using the following syntax to perform the diff backup.
backup database northwind to northwind_diff with differential
Is there a way to initilize the backup device(file) prior to the differential backup being done?

Thru maintenance plan I backup my DBs every night and the T-Logs every hour.
Now I have to set the option "select into/bulk copy" on one DB.
I schedule the differential backup every 3 hour with option "overwrite existing media", wich is, in my case, one file on disk.
My sequence of T-Logs is valid even if a non logged operations occurs?
If I have to restore this DB can I use the last full backup + the differential backup + all the logs in between?
example:
22.00 full db backup
08.00 t-log
09.00 t-log
10.00 t-log
10.30 diff backup
11.00 t-log
12.00 t-log
13.30 diff backup
14.00 t-log
15.00 t-log
Or my log are unusuable because the non logged operation?
Thank you very much.
Hello
I am using SQL 7 database maintenance plans to create full backups for all the databases on my server every night which expire after 7 days, and transaction log backups every hour on some of the databases which also expire after 7 days.
I want to add differential backups but the maintenance plan doesn't allow me to add those. How do I add them, and what naming conventions should I use? I want them to expire after 7 days, but want to backup every 4 hours.
Thanks

Hi Folks!
I did a few searches and found some interesting threads but was not able to understand much. :)
I recently jumped from support to a DBA position and am learning about SQL Server 2000.
My dilemma: We have a SQL 2000 server with about 500GB's worth of databases that has some jobs from the app locking up due to tape backups. I am performing Full nightly and 1/2hour transaction SQL backups. We run daily differential and weekly full tape backups. It is taking 14 hours to run tape backups daily, causing some of the application jobs to fail. So to test it, I stopped the tape job to run one night and none of the App jobs failed.
So, I am hoping that if I start running nightly differentials, weekly fulls, and 1/2 hour trans, it should work. However, I am not very familiar with Differential jobs as till today i have been using maintenance plans. :confused:
My ideal scenario is this: Differentials start on Sat morning and stop before the weekly backup runs on Friday and then delete the older file when starting a new one. Is this possible? how?
C= OS, D=Backup (Raid 0), G=Data (Raid 5), E=Logs(Raid5).
Any help would be appreciated, and obviously if I have missed some piece of information, please feel free to ask.
Hi,
I've defined a maintenance plan in SQL2005, which creates a differential backup of a DB daily. Suppose I'm having differential backups from May, 10 to May, 14 but backup files of May 12 and May 13 are lost (deleted unexpectedly). Am I losing some data, if I restore from backup file of May 14?
Thanks & Regards,
I'm lost. We have Sql Server 2005 on a remote box (A) and the local pc (B). Both servers have a single database on them. We've been copying the database A to B for some time and its becoming tiresome. I've heard of replication but couldnt figure out what the MS site was saying.
How do i go about making a differential copy of the A database onto B?
Thanks

Currently run a weekly (full) backup and a daily (differential) backup.
When I format the server and rebuild I restored the DB using the weekly (full) backup and all worked as it should.
When I format the server and rebuild I attempted to restore the DB using the daily (differential) backup - I got the following error:
'SPCDBDIF.BAK ' is not part of a multiple family media set. BACKUP WITH FORMAT can be used to form a new media set. RESTORE HEADERONLY is terminating abnormally. (MS SQL Server, Error: 3259)
I am sure I am not using the differential file properly. What is the proper method to restore a DB and use a differential backup?
Any insight appreciated.
Thanks,
Kerry
I need to make sure that my databases are backed up every hour so they can be recovered. What should I be doing? Transaction log backups every hour or differental backups every hour? I assume differental is better because it is cumlative, but would take up more space. Also, how long are they worth keeping around. I was thing for a day until the next full backup is run. Any thoughts?
View 4 Replies View RelatedI am using SSIS to replicate data from an AS400 mainframe to a SQL destination. I am using a lookup column to see if the primary key is duplicated and if not, it will INSERT the row. This is all working fine. What I need to know is can I also use the Lookup transformation to look for differential data and then UPDATE the row? The primary key of the table will never change, however the data might and I need the package to recognize that this is a modified row on the mainframe and that the same row on the SQL destination server needs to be updated.
Thanks for any useful information.
Hi all
Can anybody explain why the size of a differential backup in SQL7 is MUCH higher than the one in SQL2000?
Do this test yourself: do a full backup of the pubs database in SQL7 , it will be around 1.5mb, do a differential backup, and it will be 2mb or 4mb.
If you do the same tests in SQL2000 the differential backup is around 200K.
thanks
I need to replication a server database out side a firewall. But can't change the server configuring for replication, so replication is out. So I wanted to know if I have a full backup of every db send to me every 24hrs. W/ differential every hr, will the restoring process work on the restoring server? Should I restored the full 1st? I'm not sure if the restoring of the Differential will work. Any help on the steps to take, to get this to work with backups & differential will be greatly appreciated.
Thanks Reggie
PLEASE HELP...
WE ARE DOWNLOADING THE BACKUP FILE FROM OTHER BRANCH OFFICE AND THE FILE SIZE IS GROWING LIKE HELL SO I AM CHANGING THE BACKUP POLICY TO DOWNLOAD THE DIFFERENTIAL BACKUP FILES EVERYDAY. BUT EVEN THE FILE SIZE GROWS DAY BY DAY UNTILL WE TAKE THE FULL BACKUP THERE. SO I WANT TO TAKE A DIIFERNETIAL BACKUP AND THEN IMMIDIATELY A FULL BACKUP AT THE REMOTE SERVER END. SO MY NEXT DIFFERNTIAL BACKUP WILL HAVE THE DATA OF ONLY PREVIOUS DAY.
FOR THIS I AM SCHEDULING A JOB WHICH FIRST TAKES A DIFFERENTIAL BACKUP AND THEN IMMIDIATELY FULL BACKUP EVERYDAY AT 12.00AM.
BUT I HAVE A CONCERN.. WHILE TAKING THE DIFFERENTIAL BACKUP ANY TRANSACTIONS THAT ARE TO BE COMMITED WILL NOT COMMIT UNTIL THE DIFFERENTIAL BACKUP COMPLETES. BUT IMMIDIATELY I AM STARTING FULL BACKUP. IS THERE ANY CHANCE THAT A TRANSACTION GETTING COMMITTED IN BETWEEN THESE TWO STEPS. IF SO IS THERE ANY WAY .. NOT RELEASE THE DATABASE UNTILL THESE 2 BACKUPS ARE COMPLETED?? I AM RUNNING IT AS A JOB..
ANY SUGGESTION??
THANKS IN ADVANCE.. :-)

Hello,
I'm trying to run a differential backup on our new 7.0 box. It fails with an error message number 3242 "The file on Device 'E:MyFile' is not a valid Microsoft Tape Format backup set."
Why "Tape Format" if I said "Backup database [mydb] to disk"?..
When I run exactly the same query without "Differential" I got a full db backup.
Am I doing something wrong?
Thank you,
Anastasia.
I am trying to set up a process where a differential backup is taken daily and applied to another DB. For some reason I cannot get the diff backup to restore. The full DB backup restored fine.

Cannot apply the differential backup on device 'diff' to database 'test'.
Server: Msg 3013, Level 16, State 1, Line 4

Our production backup schedule is, FULL backup once a month and a DIFFERENTIAL backup every day.
We are starting the FULL and DIFFERENTIAL backups using something similar to
FULL Backup
backup database @DB to disk = @BackupFile
DIFFERENTIAL backup
backup database @DB to disk = @BackupFile WITH DIFFERENTIAL
A full backup was done on 10/6 and the DB size was 48GB. Since then we have been doing DIFFERENTIAL backups. I recently looked at the DIFFERENTIAL backup directory and found something I think is interesting.

My understanding of DIFFERENTIAL backups from books online is
"Specifies the database or file backup should consist only of the portions of the database or file changed since the last full backup"
MY Question:
Assuming I am understanding this correctly, all DIFFERENTIAL backups are independent of one another. If a failure happens, all I have to do is restore the latest FULL backup and then
restore the latest DIFFERENTIAL backup.
So, I would think the sizes of the backup files should be in ASCENDING order. Why is the size of the backup file from 10/15/2005 (1,216,000 bytes) smaller than the backup file from 10/14/2005 (120,875,520 bytes).
Assuming a crash happens on 10/15 5AM, I would restore the full backup from 10/6 and then restore the DIFF. backup from 10/15 4AM (Which will apply approx.. 1,216,000 bytes of data). So where has the data in the backup file from 10/14/2005 gone (120,875,520 bytes)?
Thanks
Hi,
I have a DB on a SQL server version SQL 2000. I have copied over one table onto a different server into a newly created DB. This DB is on SQL 2005.
The tables are identical in structure.
Now I need to copy over the differential from the Source table on the SQL 2000 server into the table on the destination server which is SQL 2005 on a daily basis.
What is the best way of doing this? It is just 1 table, I do not need the entire DB.
This table does hold a lot of records and on a daily basis there will be roughly 20,000 that need to be copied over. One of the main reasons for the differential only is that these 2 servers are physically located on different continents so the connection speed is not that great.
The table in the Source holds about 36 million records already (which I copied over to get the initial start).
Any ideas, help, suggestions are greatly appreciated.
Thanks,
Michiel

View 2 Replies View RelatedWhen a new scheduled job is created for a Differential backup, the file specified in the Destination folder is automatically created by SQL Server. After the first time the job runs, is there a way to configure SQL Server to give each Differential file a unique name, including the timestamp (i.e. similar to Full Backup jobs)? I noticed my only options are 'Append to File" and "Overwrite Existing File." If I choose to enable "Backup Set Expiration," the backup job will not run, because it wants to append/overwrite the filename specified.
