6.5 - Deleting Backup Information
Mar 12, 1999
Does anyone know a way of deleting old backup information? We'll shortly be in a position where SQL thinks we have got a certain number of backups whereas in fact the older ones will have been copied to tape & deleted. Apart from being misleading this must also be leaving redundant data in the system/control tables & I'd prefer not to have to look at increasing their size just because of this. Anyone got any tips? Thanks very much to the guys who have responded to my previous 2 questions, being new to SQL I certainly appreciate the help.

I have a transaction log which is backed up 5 times a day to a device.
The Transaction log is growing quite quickly in between each backup. The backup device is also growing at a much quicker rate.
realistically i would like to only keep 2 weeks worth of transaction log backups in the device.
for the transaction log backup i have tried the following transact-Sql
'Backup Log [imsv23] to [imsv23_TL_2] with RetainDays = 7, Init, NoUnload, Name = N'imsv23 TL V2', NoSkip,Stats=10,Noformat'
but due to all of the contents in the backup set not having expired the backup fails.
i need to reduce the size of the backup device. all of the backup sets have expiry dates but none of them are being deleted from device.
so my problem is 1 i need to remove the excessive backups from the device
2 i need to set up the automatic backups so that these datasets are removed when the expiry date is reached.
thanks in advance

I created a backup device and then scheduled a recurring backup of one of my SQL databases for SMS. I right-clicked on the database name and chose All Tasks | Backup and set a daily schedule.
Now I want to delete the whole thing and use Database Maintenance Plans instead. The backup device never showed up in Management | Backup so I deleted the backup files (and devices?) from NT Explorer. The backups still occur, I'm guessing, because I never deleted the Schedule. How do I get these backups to stop?
P.S. Forgive me if this is an elementary questions -- I am new to SQL.
Thanks.

I have created some backups where expiration dates or days to be
retained were not specified.
Using EM, how do I find the old backups.
Using EM, how do I delete the old backups (hoping this will
clean up the MSDB tables and physically delete the files
from disk).
Thanks!!!!

We are doing a full backup at night. During the day we are doing a backup of the log every hour. How do I delete the log backups from the media without deleting the device itself. I would like to do this once we have a full backup for the day. The media we are backing up the logs to is disk.

Such a simple task. Not doing as it should!!
This Maintenance Cleanup Task is set to delete all BAK and TRN files it's made (in seperate maintenance plans) in given path, with the given file extension, delete files based on the age of the file at task run time. Delete files older that 4 days.
The files are now backing up for months and months. I'm not going to take care of this. I've got a computer to do this for me, every time it runs its jobs, every 4 hours and once overnight.
This is ignoring commands and refusing to do as it's told. I've checked the settings in here over and over. It's so simple - what could be wrong? I've checked the path, the file age, the extensions... The disks are getting full!
Has anyone seen anything like this?

I am using the backup task and backing up a database but want to delete all backup files older than 5 days old. I am using the file task for this and have built the path in a variable but am trying to use a wildcard for the time. I am getting illegal character in path. How can I go about this.
I currently have E:MSSQL.1MSSQLBackupdatabasename_backup_20070309*.bak in my input variable and am trying to delete the file databasename_backup_200703091532.bak

I have a maintenance plan set to back up my 2 primary databases, one about 1 GB, the other about 2GB. I have about 4 GB available on the back up drive. I have set it to delete old backups more than 1 minute old. Problem is, the first night it works fine, the second night it sometimes it refuses to delete the old and therefore does not have enough space to complete the new back-up. Does anyone run into this before? Does it complete both back-ups THEN erase the old, in which case I need to have about 6GB available? Sometimes it works and sometimes it doesn't. It can be going along fine for weeks then stop working. Any info or links to how this is supposed to work would help.
TIA

We are getting a security audit for the company I work for and got this question recently, and while my answer would be "everything is possible", I know that DIFFs alone can't restore a SQL database.
Having said that (and don't want to read hypothetical comments) how can a hacker read confidential information from an unencrypted DIFF backup? Let's say he steals the DIFF backup alone.

Hello,
I have some troubles with IBM WebSphere Application Server using MS SQL Server 2005 JDBC Driver. I always get the error e.g.
java.lang.SecurityException: class "com.microsoft.sqlserver.jdbc.SQLServerDatabaseMetaData"'s signer information does not match signer information of other classes in the same package
I found this Feedback but it seems to be closed.
A temporary solution for me was to delete the meta-inf directory of the JAR-File, but that can't be the solution.
Can anyone help me with this problem?

Hi there
I'm getting this message on my third automated backup of the transaction logs of the day. Both databases are in full recovery mode, both successfully backed up at 01.00. The transaction logs backed up perfectly happily at 01:30 and 05:30, but failed at 09:30.
The only difference between 05:30 and 09:30's backups is that the log files were shrunk at 08:15 (the databases in question are the ones that sit under ILM2007, and keeping the log files small keeps the system running better).
Is it possible that shrinking the log files causes the database to think that there hasn't been a full database backup?
Thanks
Jane

On the SQL Server the Event Viewer shows the same messages and errors every evening between 22:05:00 and 22:08:00. The following information messages are shown for every database:
"I/O is frozen on database <database name>. No user action is required. However, if I/O is not resumed promptly, you could cancel the backup."
"I/O was resumed on database <database name>. No user action is required."
"Database backed up. Database: <database name>, creation date(time): 2003/04/08(09:13:36), pages dumped: 306, first LSN: 44:148:37, last LSN: 44:165:1, number of dump devices: 1, device information: (FILE=1, TYPE=VIRTUAL_DEVICE: {'{A79410F7-4AC5-47CE-9E9B-F91660F1072B}4'}). This is an informational message only. No user action is required."
After the 3 messages the following error message is shown for every database:
"BACKUP failed to complete the command BACKUP LOG <database name>. Check the backup application log for detailed messages."
I have added a Maintenance Plan but these jobs run after 02:00:00 at night.
Where can I find the command or setup which will backup all databases and log files at 22:00:00 in the evening?

SQL Server 2008 r2 - 6 GB memory...I attempted a backup on a 500GB database but it was taking way too long. I checked the resources on the box and saw the CPU at 100%. I checked the SQL Server activity log and saw a hung query (user was not even logged on) that had multiple threads so I killed it and now the CPU utilization is back to normal.
Trouble is, now all of the threads in the activity monitor for the backup show 'suspended' and the backup appears to be not doing anything.

Hi,
I use the Transact-SQL BACKUP statement in Visual Basic to backup my local MSSQL Database. It give me this error
Error 3041
BACKUP failed to complete the command BACKUP DATABASE [BCFPC] to BCFPCBKP
I already created a backup device called BCFPCBKP and it is backup to the disk.
I tried to run the same BACKUP statement in SQL Query Analyzer and it worked fine. I tried to run my VB application in another PC. It worked fine when i use this command remotely. Can anyone tell me what's the problem?
Thanks in advance
regards,

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?

Windows 2003 backup utility uses the shadow copy option that allows it to copy open files.
Therefore, can I use this utility to backup the .mdf and .ldf files for my SQL 2000 database?
I can then attach the .mdf files if I need to restore the database to another server.
Can anyone tell me if this is safe? I've tried it and it worked but I'm worried there maybe some lurking danger in using this approach.

We take a full backup in the early morning and hourly transaction log back during the working hours for one database in the production server. The application team made certain changes to the design of the said database in their development server. The backup from the development server was restored to the production server during working hours. After the restoration should we take a full backup before next transactional logbackup? Would the transactional log backup with out a full backup after the restoration of a database be valid?

Using SQL Server 2005 Server Management Studio, I attempted to back up a database, and received this error:
Backup failed: System.Data.SqlClient.SqlError: Backup and file manipulation operations (such as ALTER DATABASE ADD FILE) on a database must be serialized. Reissue the satement after the current backup or file manipulation is completed (Microsoft.SqlServer.Smo)

I 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...

Please HELP!!
I need a query to DELETE the first few records in a table. For example: something like .....delete top 1000 from tablename. I figured that TOP dosent work with the DELETE. It only works with SELECT and UPDATE statments.
I cannot hardcode any values in the WHERE clause due to certain constraints in my application.
KINDLY HELP, THIS IS URGENT.

This is probably a simple question but I have to ask it anyway. When backing up I can backup to a file on my local drive but I also can create a device to the same location on my local drive. Is this doing the same thing. If I so desire to backup to the local drive(bear with me) what is the difference between creating a device and a file called mybackup or just choosing to backup to a file called mybackup? Should I always create a device? I know these are dumb question but....

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,
Marc

Hi
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.

I have only one tape drive.
My server is using the SQL server 2005 backup tool and arcserve backup tool to backup different files .
Everytime I need to disable and enable the tape device driver (in device manager /windows) before I can use SQL server 2005 backup tool.
Everytime I need to disable and enable the tape device driver (in device manager /windows) before I can use arcserve backup tool.
It seems that the tape device resource is held by softwares even the tape drive is not in use.
What should I do to make the tape drive shared by different softwares?

Manuel
