Hi
Is there anyway I can implement a standby server in SQL Server 6.5 ? In addition are there any tools in the market which I can use to perform a differential backup ?
I believe SQL Server 7.0 can do this, will I be able to use ARCserverIT or seagates's backup exec to perform these functions ?

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 want to set a full and differential backup to one database in sql server 2000.
Is there a way to set both full and differential to just one database.
i want the full backup weekly once and differential every day to set up.
Please let me know
Look at this scenario
1- I have created a backup device
2- I have created a maintenance plan full backup and run it - with overwrite option on the backup device
3- I have created a maintenance plan differential backup and run it with append option on the same file of backup device
4- I have created a maintenance plan log backup with append option on the same backup device
When I made restore database from the backup device i found three files the full and differential and log backup
5- I ran again the differential backup maintenance plan ( suppose to be ran everyday night )
when i made restore database I found only two backups the full and the last differential !!!
what I want to do is to take a full backup every week , append differential backup everyday and append log backup every hour
when I ran the last differential backup it erased the first differential and log backups, why is this happening and how to apply this scenario and keep the all differential backups on the same backup device .
Hi,
After some advice - I have a SQL Server 2005 database which is part
of an anti-virus setup. The main database is 25Gb is size, and it
is running in simple recovery mode. There are two backup jobs in
place, one to do a differential backup each Mon-Sat, and one to
do a full backup on Sun. Although the backups do get done they
are taking 5 hours to do. Any wiz out there care to suggest what
the problem is, I would've though that maybe an hour was more
acceptable ?
Cheers,
Gordon
We have a 1TB Database. Our backup strategy looks like this.
Weekly Full backups - Saturday 10pm. (Takes anywhere between 5 - 9 hours)
twice Nightly Diffs (8:30p and 2:30am - Mid week this takes roughly 1.5 hours)
Hourly Log backups starting at 4:00am until 11pm.
I have an issue where I need to restore to 3:00 today. If my (2:30a)Diff is still running at that recovery point.
I am getting an error when trying to restore Full/2:30a Diff/4a Log with a stopat 3:00a.
Error telling me my log backup is incorrectly formed.
Can I, in fact, restore to this point at all? Do I need to go back to my previous Diff (8:30p) and restore the logs, if so, which ones?
My nighttime Diff ran from 8:30 - 10p.
I have logs at 9p, 10p, 11p, 4a
I have done a full backup on 3pm, and a differential backup on everyday 5pm.
I try to restore it back in my testing server and i encounter the problem in restoring the File3 and i try to restore the File 2 and it is okie. Can i know wat is the problem usually cause this error? Thank you
File 1: Full Backup
File 2: Differential Backup

Using Ola Hallengren's scripts I do a full backup of a database on a Sunday. Then differential backups every 6 hours and log backups every hour. I would like to keep a full week of backups based off the full backup done on Sunday. Is there a way for me to clear out the diff and log folders after the successful full backup on Sunday nights?
View 2 Replies View RelatedI have a database that is just over 1.5GB and the Full backup that is 13GB not sure how this is since we have compression on for full backups and my other full backups are much smaller than there respective databases...Now my full backup is taken every Sunday night and the differentials are taken every 6 hours after the full backup. Now I have been thrown into this DBA role with little to no experience just what I have picked up and read. So my understanding of backups are limited but what I think I understand is that we take a full backup and the differential only captures what changes in the database so my question is why is my database 1.5GB but my differential is 15.4GB? I have others database that are on the same instance and don't seem to have this problem. I also just noticed that we do not rebuild the index before a full backup like we do on other instances...

I am using the Simple recovery model and I'm taking a weekly full backup each Monday morning with differentials taken every 4 hours during the day.
On Wednesday afternoon, a programmer ran a process that corrupted the db and I had to restore to the most recent differential. It was 5pm in the afternoon and a differential backup had just occured at 4pm. No problem, I figured.
I restored the full backup from Monday morning and tried to restore the most recent differential backup. The differential restore failed. Since I had used T-SQL for the initial attempt, I tried using Enterprise Manager to try again.
When viewing the backup history, I see my initial full backup taken on Monday plus all the differentials. BUT, on closer inspection, I noticed another full backup in the backup history that was taken early Tuesday morning. I can't figure out where this Tuesday morning full backup came from. It wasn't taken by me (or scheduled by me) and I'm the only one with access to the server. My full backups are usually named something like HCMPRP_20070718_FULL.bak. This erroneous full backup was named something like HCMPRP_03a_361adk2k_dd53.bak. It seemed like it was a system generated name. Not something I would choose. To top it off, I could not find this backup file anywhere on the server and when I tried to restore using this full backup, it failed.
Does anyone have any clues as to where this full backup might come from? Does SQL Server trigger a full backup on its own if some threshold is reached?
I ended up having to restore using the differential taken just before this erroneous full backup and lost a day of transactions.
Any insight is greatly appreciated.
what is the differences between a differenctial backup and transaction log backup?

Using SQL Server 2005, we have a 2.8Gb database under the Simple recovery model. The database contains ~50M rows and each night ~60k rows are loaded(appended) to the database by a SSIS task.
We configured a Maintenance Plan which is executed once a week to perform a full backup of the database. The resulting backup file is ~2.8Gb, as expected.
We also configured another Maintenance Plan which is executed every day, a few hours after the SSIS task is executed, to perform a differential backup. To our surprise, the resulting backup file is about the same size as the full backup, ~2.8Gb when it should only be a few MB (only 60k rows are added to the database)
When we launch the "Restore Database" wizzard we clearly see the different backup set, Full and Differential but they all have about the same size (same for the physical backup file on disk).
Is there anything we are missing, why are the differential backup that big?
Thanks for any advice.

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.

I'm trying to create a differential backup job that run hourly and that creates a different differential files. Ext. dbfilename1am, dbfilename2am, dbfilename3am ect... Can I do this with one job? Are do I have to create a differential backup job for each hour?
Thanks
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 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
Differential back up failed , verify the network error 51
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.

View 1 Replies View RelatedI create a full backup followed by daily differential backup, when I restore database from the fifth or later differential item, I get the following Error Message:
System.Data.SqlClient.SqlError: This differential backup cannot be restored because the database has not been restored to the earlier state. (Microsoft.SqlServer.Smo)
It seems that there is an error when the fifth differential backup occurred, It's a disaster, how can I do, help!
Where can I find more about Multibase Differential Backups? I searched through BOL and MSDN (http://msdn2.microsoft.com/en-us/library/ms178046.aspx) but there is too few information (missing sample, backup syntax for selecting differential base).
Is it possible to have two (or more) bases for differential backup for one database?
How to preform such backups?
I recently started using Differential backups. They are working but are growing in size a lot quicker than I expected.
The backups are growing by 2.5GB every day although the total size of all
transaction backups is under 350MB. I would have imagined that the total transaction log backups would be a good indicator of total database changes and therefore the differential backups would approach this figure.
Please explain!

I am doing a differential backup every night with t-log backups every 15 mins. The differential backup occurs at 3:00a and is about 300 MB. The very next t-log backup at 3:15a is also about 300 MB instead of the usual 1 - 2 MB. Why is this and how can I avoid it? Is this just how SQL Server works? Do I have to do a full backup every night instead? Thanks in advance for your help.

hi seniors ,
I am running sql server 2005 under details
Microsoft SQL Server 2005 - 9.00.3033.00 (X64)
Copyright (c) 1988-2005 Microsoft Corporation
Standard Edition (64-bit)
on Windows NT 5.2 (Build 3790: Service Pack 1)
When i attempt to take differentail backup i receieved following message
"Cannot perform a differential backup for database "abc",
because a current database backup does not exist.
Perform a full database backup by reissuing BACKUP DATABASE,
omitting the WITH DIFFERENTIAL option. [SQLSTATE 42000] (Error 3035)
BACKUP DATABASE is terminating abnormally. [SQLSTATE 42000] (Error 3013)."
when i search this msg on net than i find that it is microsoft bug 863 so i found hotfixes
about this problem and tried to install but unable to install (On installation screen select feature i am unable to click on check box)
Can any one help me regarding to this issue .And more is.. full back of db "abc" exists and i never changed its location nor rename file name.
Regards
When we do a full backup the .bak file is 700MB but in the meanwhile our differential backup has grown to a size of 20GB. The backup set expires in 1 day and if the backup file already exists we "append" to it.
What we basically want is a differential backup for one day only. I realize that in SQL Server 2005 you could add a "Clean up" task but that is to delete files but because we only have 1 .bak file for the differential backup this is not an option.
If we set to overwrite the backup file if it already exists what does this mean? Assume that we run a differential backup every hour, does this mean that the differential backup file will be overwritten every hour?
How can we make sure that we have a differential backup every hour and keep only the differential backups for the last 24 hours?
Hi
Could you suggest me some of the ways to have standby database server?
All of a sudden my company is in a need for standby database server in sync upto the 10 minutes. Main production database is about 8 GB. It serves almost 6 main sites for the company. No body in my group has worked with standby server issue before.
Any suggestion would help.
