I noticed our log files are getting way too big. I found that a previous
SQL guy had set up the following scheduled job with the TSQL statement:
BACKUP LOG DEV TO DevDailyTranLog with noinit
This runs every 20 minutes.
There's also a Maint Plan to do a Complete backup every night and a
Transaction Backup every hour (could be set to 20 min)
Why do you suppose the BACKUP LOG job exists ? If the maint plan were
set to backup transaction every 20 min, wouldn't the 2 jobs be
duplicating each other ?
Also, I notice that the Tran Logs specified in the database properties
seem awfully big (4 gig), shouldn't they automatically be truncated when
the daily full backup occurs ? (full recovery model)
Feel free to call me and straighten me out or to get more info.
Has anyone been able to successfully delete old backup files(*.bak) and tran logs (*.trn) TOGETHER using maintenance plan cleanup task in SQL 2005 SP2.
this is transact sql running in the back ground. EXECUTE master.dbo.xp_delete_file 0,N'F:MSSQL.2MSSQLBackupibmdir',N'"bak" & "trn"',N'2007-03-26T22:21:14',1
This DOESNT WORK.
It works if I just try to delete only one of the things ie trn or bak files.
What is the advantage of taking frequent tran log backups (say every 30mins) as opposed to once a day? Say, I backup data and tran log once every night and I lost a table at 10:00am next day. Can't I recover the database to the point in time by restoring the previous night's backup and then applying the transaction log from previous night and then applying the transaction log (to the point int time) that you just dumped when the mishap was reported to you?
I have recently implemented a backup solution that keeps our standby server up-to-date with nightly database backup and restores. Ironed out all the problems with syslogins and orphan users. It's been working very well over the past few weeks.
On the production server we do hourly tran log dumps every hour between 8am and 10pm. I would like to implement some form of "log shipping" to bring the window of vulnerability down to 1 hour. By making some alterations to my current process I been able to incorporate the hourly log dumps in the same process.
However, when I try to restore the log on the standby servre I get the following message, Server: Msg 4305, Level 16, State 1, Line 1 Specified file 'HODB1SQLBACKUPRace_Prd_T_dump.200101231513' is out of sequence. Current time stamp is Jan 23 2001 2:01PM while dump was from Jan 23 2001 3:01PM.
After a bit of investigation I found the dumptrdate field in the sysdatabases table and it was set to Jan 23 2001 14:01. After updating this field to Jan 23 2001 14:01, I ran the load command again but received the same error message.
Is there something else that needs updating on the standby server? Is what I'm trying to do possible in 6.5? Any help or ideas would be greatly appreciated.
We're planning to implement log shipping on our databases, and I have been toiling with it all weekend trying to get it to work on some test databases. The result is the same whether I do it via the wizard or manually via T-SQL.
I am using 3 servers, all SQL Server 2005 Standard SP1. All 3 SQL Servers are configured identically.
When I setup log shipping, it initializes with no problems. When it processes the first tran log file, it restores it with no problem. Every successive log file thereafter is not restored. No errors are generated. The only outright indication of a problem is that the monitor server shows that there has not been a recent restore.
The backup and copy both suceed. The restore claims to suceed. If I review the job history for each step, it says that it skipped the log file and then reports that it did not fina any log files to restore.

Hello, I have MS SQL 2005 server with 300+ databases on it. The application is set up that way that it creates a new database as needed (dynamically). Do not ask me why - I hate this design... So, it can create 3-4 databases a day (random time). I've scheduled full backup of all databases to run once at night, and it runs just fine. Besides that, I have scheduled tran logs backup of all databases to run every hour. This backup fails from time to time with the following error:
Executing the query "BACKUP LOG [survey_p0886464_test] TO DISK = N'D:\backups\log backups\survey_p0886464_test_backup_200708072300.trn' WITH NOFORMAT, NOINIT, NAME = N'survey_p0886464_test_backup_20070807230002', SKIP, REWIND, NOUNLOAD, STATS = 10 " failed with the following error: "BACKUP LOG cannot be performed because there is no current database backup. BACKUP LOG is terminating abnormally.". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly.
So, I think what happens is since my full backup of all databases are scheduled to run only once at night, and tran logs every hour, when new database is created during the day, there is no full backup for it, that is why tran logs backup fails. Becuase after the failure, if I run full backup again, then tran log runs just fine afterwards.
I am new to MS SQL Server, I am mostly working with Sybase IQ. Do you know if I can "trigger" full backup every time when new database created to avoid tran lof failure?
Or is it possible to schedule full backup to run if tran log backup fails? Any advice will be much appreciated.
I have 30 databases on sql server 2005 that I need to do a full backup every morning at 7:00 and tran log backup every 30 minutes until 7:00 PM. If I create a maintenance plan for a backup using the wizard I have the option of starting a full backup at 7 am and then an option of doing tran log backups every hour using a different schedule. I plan on selecting the option to create a different folder for every database. I just need to confirm that in this way the way to restore the data would be
1. to restore a full backup
2. apply all the tran logs depending on the time they want to recover back to.
I just think this is the easiest approach to have 30 databases on the same backup scheme instead of creating a separate backup device for each database and doing a full backup on that device and appending all tran logs to that device which means just 1 bak file versus the above strategy with a number of tran log files. Please advise.
I have my tran log backup running every 30 mins. One of the log backups took 36 mins to complete. So at a time I would have two log backups taking place. It seems to me that the 2nd log back up did not happen at all ( I checked in the EM) as the first one wasn't completed by then.
I have maintenance plan on DBABC backup log to .trn job to run every 90 minutes (daily).
in order to keep the log file small, I also set up a job (T-SQL) to run at 4:15 am to backup log ABC with truncate_only, then run dbcc shrinkdatabase (DBABC, 10)
it looks "backup log ABC with truncate_only" has conflicts with the every90 minutes backup transaction log.
Question: could I keep the backup transaction log every90 minutes, but still could shrink the log file. The log file is growing very fast.
Or I have to use differential backup instead of backup tran log?
I have full backups scheduled weekly, differentails scheduled daily and tran log ackups scheduled for every 15 minutes.
The tran log backups only work for the first 40 minutes or so after the daily backup. Once the daily has occured, the tran backups will work again, but for only 40 minutes.
I run consistency checks on the db daily and there are no errors.
The error returned from the tran log backup is 'BACKUP LOG cannot be performed because there is no current database backup'
I am running an Execute SQL task that does a Begin Tran, then the next task in the sequence is a data task which imports a XML file into two tables. If i doo a Rollback Tran only one of the two tables is rolled back.
Is it possible to have both tables rolled back from one Begin tran command or do i need to split the datatasl into two and treat each import as a seperate issue ?
I want to rollback my t-sql if it encounters an error. I wrote this code:
begin tran mytrans; insert into table1 values (1, 'test'); insert into table1 values (1, 'jsaureouwrolsjflseorwurw'); -- it will encounter error here since max value to be inputted is 10 commit tran mytrans;
I forced my insert to have an error by putting a value that exceeds the data size. However, I didn't do any rollback. Anything i missed out?
I've truncated and shrunk the database and now, it says that the size of the db is 14 mb and 8mb is free. However, on the file system, the mdb and ldb files together adds up to 14 mb. How can I free up the 8 mb for other usage?
Help on Backup of Logs I get the following errors when I am trying to backup log every 15 minutes. It fails only during the peak hours.Does anyone have any ideas why it happens.
Cannot allow BACKUP LOG because file 'XX_data' 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 4200
I am trying to backup my Transaction Logs using T-SQL with the aid of a job. The problem I am running into is that I need it to backup every three hours and retain one days worth of transactional logs. This is the query I got so far.
BACKUP LOG CA001 TO DISK = 'S:AZTARGPCA001ca001_TRN_bkuplog.trn' with retaindays = 1
I've got a Sql server 2000 box that currently backs up to tape in full every night. I also want to back the box up off site but not in full (as 30GB is a little too much to transfer every evening).
So my plan was to do a full backup to tape at 7pm then a differential at 8pm (to transfer off site).
The problem I am having is that after my differential has been done the logs get truncated so if I want to replay them for any reason I need to get that differential back to site.
We have received a backup file that is 6G in size. The log file isabout 74G while the MDF is about 5 G when we restored. Is there a wayto run a SQL script to restore the .BAK file without restoring the logfile as we do not have enough space on the server.PS. We are running Sql2K5.Thanks!
I have configured maintenace plan to do a full backup of sql server at 5:00 Am followed by transaction log backup every 15 mts.The transaction log backup basically appends to existing backups so there is only one file of transaction log backup. I want to modify that the transaction logs backup only has transaction logs after 5:00 Am full backup.Right now the transaction backup has backup of all the transaction logs since i have scheduled.
I am in the process of migrating databases from a SQL Server 2000 server to a 2005 server.
I have taken full backups and restored without recovery on the 2005 server. I now need to take transaction log backups and restore with recovery tonight to complete the operation. My question is this:
Some of the transaction logs have grown very large. Is it safe practice to perform a backup tran with truncate only and then run dbcc shrinkfile to reduce the size before I back up? This would make the process much quicker.
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
Is there any problem with implementating some kind of replication andbacking up transaction logs at the same time? SQL Server 2000 StandardEditionThe server is configured to back up log files regularly, with thepresenceof a(New) Disaster recovery server and with an inability forstandby(Standard Edition)I am planning to implement some kind ofreplication hopefully still backing up the transaction logs to enablea point in time recovery.Thanks in advance for your great ideasVincento
I've got a couple of backup database tasks setup to run one after the other. The are set up the same, Alldatabases, backup to a device each, and overwrite every time. The task on databases full works fine but the one on logs fails every time, right away with the following rather esoteric error pulled from logging in the event log. Event Type: Error Event Source: SQLISPackage Event Category: None Event ID: 12550 Date: 29/01/2008 Time: 09:54:11 User: OILCATSsqlservice Computer: GUNKVBPROC Description: Event Name: OnError Message: The Execute method on the task returned error code 0x80004003 (Object reference not set to an instance of an object.). The Execute method must succeed, and indicate the result using an "out" parameter.

What is this elusive Execute method that is only relevant to the log aspect of this task?
We run a disk backup (full) early in the evening, and then another bull backup to tape later at night. We also keep independent backups of the logs.
It seems that any full backup "resets" the ability to apply logs when restoring?
I want to be able to restore a full backup, and apply logs forward possibly more than 1 day, in case a backup is corrupted and not usable. But it seems I can only apply logs up until the time of the next full backup.
Hi guys, just wanna ask about the backup and restore database method. What's the best way for database and restore which able to view all the transaction logs after the database being restored. Currently I backup my database daily for recovery purposes. However, if I restore the backup file at another server and use SQL log application for viewing the prefer database's transaction log, it shows all the previous log had been truncated.
Therefore, I want to know is there any way that able to get the transaction logs after restore from a database backup file? Hope able to get any assistance here as soon as possible. Thank you.
In my case I have to log the errors raised by any task in a package to either windows event log, text file or SQL server. Also I need to send an email notifications to a group of people telling them about the error.
Now can I use SSIS package logging for logging the errors into the required destinations. I mean right clicking on the package and selecting Logging, then adding the required log providers and enabling the events for logging into those. I think I have to upfront select the log providers to log the error, I will not have the liberty to log the error to the destination, the name of which is passed as a variable to the package. This is okay with me though.
Now what will a custom log provider help me to do in this case. Also can I somehow configure my package to call the send mail task everytime an error is raised.
Also, one more option can be developing a package that only does the error handling. It will take in the paramters or the error codes and descriptions, the destination to write to and a flag to send mail or not for that particular type of error.
I have a transaction log that is over f gig in size....what can be done with this..and what are the pros and cons if I delete it...also how can I keep this from getting that big in the future. Thanks!
On my SQL 6.5 box, I have a corrupt Tran log. I do not use my Tran log but now I am getting an 1105 error, that the log is full. I run Dump tran with no log but it does not work. I cannot perform any other function without getting the 1105 error. Now I tried to reboot and now it is hanging during reboot. It is hanging while checking the partition where the tran log resides. I went in to VGA Mode. Any ideas would be appreciated.
Does this seem right? We have our transaction logs set to "Truncate Log on Checkpoint" and they still grow over 1GB. Is it possible that one transaction (to a checkpoint) generates this much logged information? Will transaction log backups every 5-10 minutes help me out better or is this just a poorly written application?
