Backup Transaction Logs And Replication Simultaneously
Jul 20, 2005
Is there any problem with implementating some kind of replication and
backing up transaction logs at the same time? SQL Server 2000 Standard
Edition
The server is configured to back up log files regularly, with the
presence
of a(New) Disaster recovery server and with an inability for
standby(Standard Edition)I am planning to implement some kind of
replication hopefully still backing up the transaction logs to enable
a point in time recovery.
Thanks in advance for your great ideas

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
Any suggestions welcomed.

Hi:
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.
Thanks for your help.

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

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.
Best Regards,
Hans

Alright, here's the deal. I'm testing some backup/restore strategies, and hitting a (slight) sticking point.
We've got collections of database and log backups created by the usual maintenance plans on a 2000 Enterprise machine. I'm trying to run through a restore onto a new 2005 machine (Developer Edition on my test workstation) using the collection of .bak and .trn files copied from the 2000 server. When I try to restore to a new database on 2005 via SSMS, and select all the .bak and .trn files for the restore, I get the ol' "The volume on device '[trimmed]' is not part of a multiple family media set. BACKUP WITH FORMAT can be used to form a new media set." error.
I'm assuming this just means that SQL Server can't verify that these log backups are in fact part of a functional "set", even if they aren't part of a traditional backup media set. Is there any way to tell SSMS, "It's okay man, just restore the database from these files, in this order - trust me," or is the only solution restoring every individual log file one at a time? (Which seems to work fine, though is a tremendous pain with any more than a few log backups.) Seems like there ought to be a good one-shot method to restore a bunch of backups to a different server, and I'm just not finding it.

to take the transaction log back up regularly I should have truncate log on check point false. If I do so then how will I truncate the log.

I need to move transaction logs to a different drive and am looking for a way to do it without detaching the db.
Can I create a second transaction log file for the DB and then delete the original log file?
What is the best way to do this for db's that are being replicated?
Thanks,
Ken Nicholson

i have several sql servers doing maintenance plans and backing up the transaction logs to tape. unfortunately it seems that the server keeps adding the transaction logs to the same tape, without overwriting them. Nowadays a transaction log backup to disk takes 2 minutes but when done to tape it is taking up 1hr54minutes. What can i do so that the tape is automatically initialised without having to do it manually... Thanks

through the FC. then we put *.bak and *.trn on to local disk RAID 1 drive?
Any performance isues?

Is there a way to view the transactions from a .TRN transaction log file? If so can I overwrite some of the transactions on the file and then restore from it? I am just curious.

Hi, I know just about nothing about SQL Server. I am getting this error:The log file for database 'my_database' is full. Back up the transaction logfor the database to free up some log space.I can't access the transaction logs to back them up. I am told that my ISP'stech support should have it set up to shrink those logs automatically everyso often. Is that true?Why are they needed? Up till Monday, the logs are just of our getting SQLServer set up, so couldn't the logs just be deleted? Most of my site can'trun with this problem.I'd appreciate any enlightenment anyone can give me!Thanks, Jill

This seems like it'd be a really stupid question, but for the life of me Ihaven't been able to find an answer that works....I have a database that's approximately 400MB when shrunk... and thetransaction logs are at about 4.8GB when shrunk... I can't seem to get thetransaction log any smaller, no what I try. How can I get the log downbelow 1GB and keep it there? I've only got an 18GB hard drive and I need torun 2 copies of this database.-steve

Hello,
I am trying to figure out the time a certain store procedure was executed. I know the SP's name and approximetly the time it was executed. Is this possible to do?
Honestly, i am not sure if SQL server 2005 is smart enough to keep track of commited transaction on the server.
Any suggestins?
Thanks

I have seen quite a few people post this type of problem, but I am finding few solutions. Your advice and/or experiences are greatly appreciated.
Here's my scenario:
Environment: Windows NT 4.0 SP 6, SQL 7.0 (set up for Transactional Replication)
Problem: We have several remote dB machines configured for full recovery. On these machines are several dB's that are capturing aprox. 280 data points per second per unit. (Each dB represents one unit, and we have 21 units) No problem here. The problem is the transaction logs, that obviously grow profusely, will not SHRINK after, backups, dbcc commands and TSQL has been issued in failed attempts to shrink the logs. (in other words we've tried everything)
My questions are:
1. Because we are replicating, is it absolutely necessary to configure dB's for FULL recovery? How do I check in 7.0 if the dB is certainly in FULL vs. SIMPLE recovery mode?
2. I work with SQL 2000 and shrinking files is no problem. How can we shrink these log files in SQL 7.0?
It is rather urgent I find a solution as we are running out of hard drive space on our remote machines. Please help :-(

Currently, my databases and their corresponding transaction logs are all on the same disk array. I finally was able to acquire a seperate disk, specifically to seperate the logs, in case of failure, etc.
Now, I need to figure out how to go about moving the tansaction logs off the current disk array and on to the new disk.
In Enterprise Manager, I brought up "Properties" for the first database, and went to the "Transaction Log" tab. Clicked on the "browse" or "..." button in the location field and got the following message:
"A transaction log file's physical name cannot be changed once the transaction log file has been created". :(
I have been looking through Books On Line, but have been unable to find anything helpful yet.
Can anyone help me figure out how to go about moving a transaction log's location? There has to be some way.
Even if it involves shutting down the server, altering system tables, etc. I need to get these moved.
Your help is appreciated. Thanks.

Hi all,
I have set up a maintenance plan to backup my databases but when I view the maintenance plan history the transaction log backup steps have a success tick but a message saying :
"Backup can not be performed on this database. This sub task is ignored"
I have looked in my backup directory and only see *.BAK files and no *.TRN.
The transaction logs are supposed to back up at 1AM and the databases at 2AM
All my databases being backed up have the truncate log on checkpoint option set. Is this best practise according to my backup schedule ?
Help !!!!
Regards,
Tim

Hi all,
I am restoring database from Transaction Logs. I followed all the steps
mentioned in the book. Just before the last step there are three options
1. Leave Database Operational. No Additional Logs can be Restored.
2. Leave Database Nonoperational But Able to Restore Additional
Transaction Logs.
3. Leave Database Read_Only And Able To Restore Additional Transaction Logs.
Option 2 and 3 aresupposed to set on the NORECOVERY flag.
I tried both options 2, and 3 , But still got messages that I did not
specify WITH NORECOVERY or WITH STANDBY.
Can anyone please tell me what I am doing wrong?
Thanks in Advance.

I am currently having a problem with a transaction log not emptying even when backed up and truncated. I have done a full database backup and then a transaction log backup expecting this to flush the log however the log is not emptied and it is growing larger and larger. Even when I truncate the log it still doesn't free any space up. Can anybody out there spot the fundemental error in my working??? most grateful. Andy (SQL allegedly)

I have a MS SQL Server 6.5/SP5A database running on NT 4.0/SP4 Enterprise Edition with MS Cluster Server. On my Production box, I dump the transaction logs every 30 minutes. I need to recreate a point in time on a separate TEST box with the same hardware/software. I created a "DBA database" from a previous night of Production - no problem. However, when I start applying the transaction logs, it complains about being out of sequence. The timestamps that it is reporting are accurate for the transaction logs, but it is basically using the database load time to compare it with. (Granted I am moving from one box to another, but I didn't think this would be a problem). I created a "DBA database" on Production, went through the same steps, and it takes the database load and the transaction logs. I am assuming that the sequence numbers on the transaction logs are identified internally on the file, not per server? Ideas as to why it would complain on an out of sequence condition (Error 4305) when I move to a different box?
