Strange Backup Transaction Log
Jul 20, 2005
hello
I make every week on sunday a full backup of my database(mdf =60MB / ldf =
300MB)
additional i make daily from monday to saturday(6.00/12.00/18.00) three
times a backup of the transaction log
now I receive follow model of the backed up transactionfiles :
1.11.2004 6.00 log =130MB
1.11.2004 12.00 log = 0.2 MB
1.11.2004 18.00 log = 0.2 MB
2.11.2004 6.00 log =130MB
2.11.2004 12.00 log = 0.2 MB
2.11.2004 18.00 log = 0.2 MB
why the backup log file is alway so big at 6.00 o'clock??
nobody is working on this database!!!
thanks for your help

Hello Faculties,Currently i'm working on a local machine that houses SQL Serverdatabases. All the development work is done on this local machine. Thedata is finally imported to a remote server where a demo is given to theclients.As a result, the remote database has become full of databases many ofwhich are not needed at the moment.I plan to remove all unwanted databases on the remote server onlyafter taking backups. But there's very little space on the remote serverand as a result i wont be able to use BACKUP commands to create backupcopies.I also wont be able to import these databases from the remote serverto the local server.I am planning to copy the .mdf and .ldf files from remote server tolocal server. Will that be OK?*** Sent via Developersdex http://www.developersdex.com ***

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?

I have a SSIS package that is run from one job, nowhere else. The package has TransactionOption NotSupported.
In the SSIS package I first have a sequence container that has TransactionOption Required (Serializable). The sequence container contains several Execute SQL tasks that access the same SQL Server 2005 database. The Execute SQL tasks have TransactionOption supported / Serializable. The first SQL statement is:
select p.column_name
from table_name p with (XLOCK, ROWLOCK)
where p.second_column_name = 'COLUMN_VALUE'
After this there are a couple of SQL tasks, and finally a task containing the following SQL:
select p.third_column_name
from table_name p
where p.second_colomn_name = 'COLUNM_NAME'
The idea is that the first query exclusively locks the row in the table_name-table for mutual exclusion purposes, i.e. so that if for some reason the SSIS package would be executed simultaneously two or more times, only one package execution could lock the row and proceed and the other executions will have to wait. There's an index on column second_column_name in the table to avoid the select locking other rows in addition to the required row.
Some questions:
1) Is it so in my setup that when SSIS runtime executes the sequence container it creates a transaction in the beginning of the sequence container and commits the transaction in the end of the sequence container? And in my setup the Execute SQL tasks in the sequence containar are executed under the same transaction?
2) I have a problem that the second query sometimes gives this error:"ErrorCode: -1073548784. ErrorDescription: Executing the query "XXXXX" failed with the following error: "Transaction (Process ID 73) was deadlocked on lock resources with another process and has been chosen as the deadlock victim. Rerun the transaction.". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly."
The 1st query has locked the row for the transaction. How can the second query be deadlocked, shouldn't the transaction have a lock on the row? I'd understand if the 1st query failed sometimes, but don't understand how the 2nd quey can fail.

Hi
I have two database called test1 and test2 both are of same size(both device and log). I run the following statements to take the backup of both the databases using the tape device 'tapedevice1'. dump database test1 to 'tapedevice1'
dump database test2 to 'tapedevice1'
After this I run the load statement
load database test2 from 'tapedevice1'.
It just restore the database test2 with test1 data which is added first to the tape with a warning.
Is there any restriction that in a single tape backup of more than one database is not possible.
Your valuable suggestion appreciated

Hello, everyone:
I just heard that for restore purpose, ths full backup and transaction log backup should be from one maintenance plan. Otherwise transaction log backup files cannot be restored after restoring full backup files.
Is it true? Can anyone offer official documents?
In my system, full and transaction backups are from one maintenance plan. Restores are doing fine. I am not sure that ideal is true or not.
Thanks

I neglected to backup the transaction log as part of the process of backing up the database. Now i only have the backup file for the database and no transaction log backup. When i try to do a restore on the database, i get the error on a "tail log missing" message (which i'm assuming is that it's looking for the t-log backup?).
Is it possible to restore or even restore to a new database? I'm only looking to retreive data from 2 tables within the backup file.
Thanks!
SQL Server 2005 on Windows 2003 Server x64.

Hi
I have a full backup and transaction log backup strategy for my test server.
My transaction log backup is failing as some user must have run some nonlogged operation. Is there any way to find out what is causing transaction log backup to fail?
Any hint would be appreciated.

I have a problem w/ my Transaction Log Backup. The backup files continues to grow and grow and grow. I have created a new Transaction Log backup through EM, but instead of appending each backup to the existing backup file, I overwrite the existing backup file. My gut feeling is that this is not right. If it isn't, then how can I continue to backup my TL's w/o having the file growing at an astronomical pace?
I would appreciate your help

Is there a possibility to recover a database up to the point of failure ?
I have a database with a primary datafile and a transaction logfile.
I have backup of the database and transaction log backups upto an hour before failure. But I also want to recover one hour data which is in the transaction log.
I have lost my primary datafile.
Is there a way to recover ?
How do I backup the transaction log before starting restore ?
Thanks,
Bala

Hi friends,
I have set up the Transaction Log backup on one server he was running fine for few hour later he failed for two times and then after full backup it is running fine.
Can any one of shed some light on this issue.
Error:
Cannot allow BACKUP LOG because file 'ZTVData' has been subjected to nonlogged updates and cannot be rolled forward. Perform a full database, or differential database, backup. [SQLSTATE 42000] (Error 4213) Backup or restore operation terminating abnormally. [SQLSTATE 42000] (Error 3013). The step failed.
Thank You,

Hi!
Does the command,
backup log <database name> to <backup device name>
clear the inactive portions of the transaction log?

I've set up 4 database maintenance plans for my databases. 1 for all system databases, and the other three for specific databases. they back up to a network drive on another computer.
The plans are set up to do complete backups every day and then transaction log backups every 15 minutes.
The complete backups work fine. They all create the backups on the network drive. The transaction log backups are only created for one of the databases though. All the others report "successful completion" but they don't actually create the backup file. I looked at the report created and it never has a step that backs up the transaction log. I compared the T-SQL code from the one transaction backup job that works to one that doesn't and all the commands are exactly the same (aside from different directories to save in to, job numbers, etc).
Does anyone have any idea what is going on? I've deleted the maintenance plans and recreated them to no avail. I've also created an on the side differential backup that works as well.
Any help would be appreciated

I am using ArcserveIT 2000 SQL Agent to backup my SQL Server 7.0 db. I perform a full backup (with archive on) every day. ArcserveIT backsup both database and transaction log files. 'Truncate log on chkpt' is set to False in the databases. If I don't use SQL server's backup command with trunc. log on chkpt to true, will the transaction log file ever get trimmed? Does a third party backup utility like ArcserveIT will do something similar to 'backup command' in SQL server 7.
Anyone using ArcserveIT SQL Server 7.0 Agent, please comment.
Thanks

Good afternoon,
Has anyone ever had an issue with a Transaction Log being backed up but not truncating? We’ve been having trouble with this and now have to truncate the log manually. Any information at this point will be useful. Thank you.

What is the proper way to backup a transaction log for a database whose name contains a space. (I.E. DBname = Database Name). I am trying to execute a command, but it does not like the space in the database name. I have also tried wrapping the name in single quotes and parethesis to no avail.

Hello!!I am relatively new to SQL and am having a problem. I have taken overa SQL 2000 db that did not have any backup plans scheduled for it. Icreated a maintenance plan that backs up the database every night andanother plan that backs up the system databases once a week. I ranboth these jobs successfully, but when I created a third plan tobackup the transaction log it fails with the following message:Executed as user: NT AUTHORITYSYSTEM. sqlmaint.exe failed. [SQLSTATE42000] (Error 22029). The step failed. I then executed the followingstatement: sp_grantlogin 'NT AuthoritySystem' which did not work.I still do not understand why I can't backup the log? The databasebacks up fine with no errors so it can't be a permission thing and Icreated the job with a maintenance plan so it has to be in fullrecovery mode. Right? How do I tell? Thank you for all yourresponses!!NS

Thanks a lot for all the replies.
I'm trying to set up a job to do transaction log backup. I used the maintainence plan to create the job. the code is quite long and not very straight forward, I do not even see the BACKUP LOG .. command. Do people usually use maintainence plan for this purpose or they write their own script and then create the job?

Hi,
I have one doubt about Transaction backup. I want to take backup of highly growing database. I will take full backup every 3 days, differential backup every 1 day and transaction backup every 6 hours.
Now my question is-
When I take a transaction backup do it take backup of all transactions which are currently in progress and not committed in database?
OR What are the chances of loosing transactions which are currently running on system while I take a backup?
Thanks in advance.

We are experiencing problems with our transaction log backup. The follow error appears when we attempt the backup.
"Backup, CHECKALOC, bulk copy, SELECT INTO, and file manipulation (such as CREATE FILE) operations on a datbase must be serialized. Reissue the statement after the current backup, CHECKALLOC or the file manipulation operation is completed."
We turned on "Truncate Log on Checkpoint" and created an online backup. Then we turned off "Truncate Log on Checkpoint" and manually saved the transaction log to tape. We thought all was well until the scheduled job to backup the transaction log to tape brought back the same error.
Any suggestions? Thank you!!

We have a job created by the maintenance job wizard that backs up the transaction logs for all of our databases on an hourly basis. At random intervals, one of the tranaction log backups will fail with the following message in the job history:
sqlmaint.exe failed. [SQLSTATE 42000] (Error 22029). The step failed.
The next scheduled transaction log backup will run fine the next hour. The sqlmaint.exe is present and executable. There are no additional messages in the SQL Server error log or SQL Agent error log. Any ideas what causes this random failure?

I seem to have a problem with my SQL Server log backup system. First I was receiving alerts that the log file was filling up, so I increased it from 3Mb to 150Mb, but then I got another alert saying the same thing, later on I got an alert saying that the log backup had failed. I then decided to truncate the log and do a full backup after as suggested, however this did not work, I don't know if I am doing something wrong, this is really confusing and frustrating.

I have scheduled transaction log backups to occur every 15 minutes with database backups every sunday at 1.00AM and differential db backups every day at 1.30AM.
While viewing the job history of the transaction log backups through enterprise manager, I noticed that one transaction log backup had failed at 1.00AM on sunday. The error message was,
"Backup, CHECKALLOC, bulk copy, SELECT INTO, and file manipulation (such as CREATE FILE) operations on a database must be serialized. Reissue the statement after the current backup, CHECKALLOC, or file manipulation operation is completed. [SQLSTATE 42000] (Error 3023) Backup or restore operation terminating abnormally. [SQLSTATE 42000] (Error 3013). The step failed. "
Please let me know what the error message implies. Will there be any problem if the transaction log backup takes place at the same time as the full database backup or diff. db backup?
Thankyou.

If we choose "truncate log on checkpoint", then we cannot backup the transaction. May someone tell me what's the difference between them and the advantage over the the other.
