This is a silly question but I am not sure of the answer.
Each day I do a complete DB backup and houly I backup the Translog file with the append mode.
Question Is the Transaction log truncated each time I do a Transaction Log Backup?
SQL7:
I have a 300MB db, and a transaction log near 1.3GB. Upon notification, I backed up the db log with truncate_only - no luck getting it smaller. Later, tried backup with no_log ( assuming the o/s was full - no diff)
I tried shinkfile (logfile,truncateonly) and no luck.
I tried dbcc opentrans to see if any pending trans. The db looks fine with dbcc checkdb. I managed to free up a mere 50MB. I checked the permissions on the db, and added backup db, and backup log in the db permissions for the user logged in (also tried this with sa)
I am unable to free up the space to the os. Can I somehow rid the log file and start off with a fresh log file? I need this space. As a patch I moved the log to a larger filesystem as a temporarily fix.
start/stop SQL- nothing? reboot -nothing? I played with waiting game. This log does not want to release space. The log grew from data loads.
Question1: Suggestions how to truncate this log? The contents are not really impt, but the space is.
Question2: Can I add another logfile, then use EMPTYFILE to transfer the contents to the newly added log file, then REMOVE The original logfile? In theory does this make sense?
Thanks,
Jason
Does anyone know who I can truncate the transaction log of a database that
is on a linked server?
TRUNCATE LOG [linked server].[dbo].[database] WITH TRUNCATE_ONLY
does not work.
Thanks,

I have a trans log backup that runs every 15 minutes on san, works fine until I do a backup after a large load. I get the below error message. Anyone had this before?
Executed as user: DPSCSDOMsqlexec. The file on device 'n:sqllogsmdentallgdmp' is not a valid Microsoft Tape Format backup set. [SQLSTATE 42000] (Error 3242) BACKUP LOG is terminating abnormally. [SQLSTATE 42000] (Error 3013). The step fail
Is there anyway in SQL to backup the Database and Transaction log without truncte the Transaction log? :o. I would like to keep all or as much of the Transaction log info as possable. I know the Trans log will get large but HD space is not a problem. I use the transaction log to report field changes usung Log Explorer.
Thanks
Hi Every one,
According to our stratergy we are taking trans log backup of every user database everuy two hours.things seem to work great and with success at the day time and at night once at 12.03 and 2.03 they fail and when i checked the error log i found that there is only one database for which its failing and it gives the following error.
Database ors: Transaction Log Backup...
Destination: [D:BackupTranLogorsors_tlog_200108280203.TRN]

We had a option called select into/bulccopy set which i disabled once this failure has occured but still the problem persists....there are no other options set...i am out of resources i donno what to do..could you suggest me something and how to solve this problem its happening in prod.
Thanks for your help.

Hi,
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.
Thanks.
Hi,
Can someone please express their experience and recommendations for the following questions?
1. Do you need to unable SQL-Backup if you already using a 3rd party software utility to backup the SQL data drives?
2. If you do not want to shutdown SQL services for backup can you use Volume Shadow Copy as a solution to open files?
3. What size would you recommended to use for the Transaction Logs DB if my Data DB size is 2GB
I am running Windows 2003 with SQL 2000/SP3. Obviously, I am not an expert in SQL so I appreciate your help.
Thanks
how do i modify this so that it will truncate the log before backup?
SQLMAINT.EXE -D mimi-BkUpDB E:SQLBackups -BkUpMedia DISK -DelBkUps 1 -Rpt E:SQLMaintmimi_maint.rpt
thanks
According to BOL<---BACKUP LOGSpecifies a backup of the transaction log only. The log is backed upfrom the last successfully executed LOG backup to the current end ofthe log. Once the log is backed up, the space may be truncated when nolonger required by replication or active transactions.--->Does this mean I could do something else to truncate the log or is itsaying that the backup log command may truncate the log if it feelslike it?I want ot get a log from a client site onto my server for analysis butI want ot make absolute certain that my backing up the log on theirserver won't truncate it there.

I wanna use backup database task in SSIS to implement SQL statement
BACKUP LOG WITH truncate only.
But in this task, seems that you must at least to choose a location to store backup. No way to just truncate log in SSIS?
any help will be appreciated.
I have been unsuccessful in getting the Backup Log with
No Truncate option to work.
Any tips, tricks, suggestions, etc., would be appreciated.
Thanks!!!
Hi all,If I set recovery model SIMPLE then truncation of log files will beautomated , but I will losedatabase changes made since the last backup was taken.Is there any way to automate truncation of log file andbackup of database upto last change has been done????Plz Help.
View 3 Replies View RelatedI would like to know what happens if i shrink the database with truncate only option and do a full backup or transaction log backup ? are the full backup or transaction log backup valid?

View 9 Replies View RelatedHello all - I have a SQL Server 2000 database setup using the Full Recovery Model. Each night, we backup the entire database, and as such would like to truncate the log at this time as well.
Is the best way to do this to also backup the Transaction Log, and then perform a DBCC SHRINKFILE command? It just seems like there should be an easier way...?
Thanks!
With a database size of almost 2 GB, I run the 'truncate table eventlog command' which completes successfully, but the database size only decreases by about 10 MB so stays too large - indeed the number of rows in the eventlog table is minimal, but the otehr tables in this database don't show such an amount of tables large enough to cause the size issue either. What could be the reason and how can I reduce it (possibly truncating another table but then which one, how could I determine which is too large and needs truncating?).
View 3 Replies View RelatedHi all...
Please forgive the elementary nature of my question, but could someone please explain the differences between these two database backup types:
1. Log backup
2. Log backup no truncate
From what I understand and have read, the "no truncate" backup method keeps the entire transaction log indefinitely. Using the truncation method, the transaction log is either 1) compressed or 2) cleaned up so that any completed transactions are removed from the log. Which one of these is true?
And, for the big question: is it better to run a backup of the transaction log with truncation or not? Our current backup scheme is similar to the following:
Full backup every 24 hours
transaction log backup every hour with no truncation
Should we insert a truncation backup somewhere in here? What is the danger of removing (or compressing) parts of the transaction log? Will this affect the restore process?
Thanks in advance!
I wnat to have a log file with all the updates and inserts made to the DB.
I understand I have to do a trans-log,how?
in order to make a query a transaction do I only have to declare trans...commit ??

I have set up a simple trans rep from a server in the office to the web. both servers are NT4sp6aSQL 7.0. Tables only.
The publication and distribution db are on the server at the office, and there is a full time connection through the firewall.
The initialization and first replication works perfectly, but after that, there is a message from the snapshot agent that "no subscriptions needed initialization", the logreader says thare are no replicated transactions and the Distribution agent says there are no replicated transactions. What am I missing?
Thanks in advance
Does anyone know how to move the transaction log(s) of a LIVE database to a new location. I must move the log of a database to a new mirrored drive without any disruption to users. I cannot take the database offline or use the sp_detach_db stored procedure. Your inputs are much appreciated!

Here's my situation (SQL2K)
We have a testing database we're using to convert large amounts of data from 1 system to another. We might process 5-6 million records, but don't care about being able to recover point-in-time.
I set recovery mode to simple, do a full backup every night. I keep getting large transaction logs. I manually run Shrink Database when I realize the logs are big
What can I do to prevent the logs from getting big in the first place ?? Can I prevent logging from happening ?
I keep reading various books and BOL, but I guess I don't quite "get it" yet ......
Any plain spoken, detailed suggestions would be very appreciated .... thanks in advance.

If you are set up for AutoCommit why would you or should you set a explicit transaction? I have noticed that in some called stored procudures from a "container" stored procedure. (Hope I got that right) that in the called stored procedure a Begin tran is used. Can anyone help with the why and what fors? It seems to me that you want to let SQL Server handle this becuase of the danger of leaving out a Commit or Rollback? But thats me. I may be very wrong? Thanks.

Hi,
I was just wondering, if I have a DB for log shipping, and change the recovery model to bulk-insert before I do a dbreindex, does the log still grow as big as the full recovery model? as in when the DB in bulk-insert model, will dbreindex still writes to the log? What i'm trying to do is try to make the log files smaller for log ship when i'm doing the db reindexing job.
Thanks.
I’m really scratching my head with this Transact-SQL, say you wanted to cycle through a set of rows, then perform an operation on each row, so in VB/DAO it might look like this:
Dim rsTables As Recordset, rsIndex As Recordset
Set rsTables = dbSource.OpenRecordset("SELECT * FROM INFORMATION_SCHEMA.tables")
Do While rsTables.EOF
Set rsIndex = dbSource.OpenRecordset("Select * From SysIndexes Where Name = '" & rsTables!Table_Name & "'")
DoSomethingToIndex rsIndex!Name
rsTables.MoveNext
Loop
How can you do this cycling with Trans-SQL?
Hi all,
Just wondering if the virtual filesize of the transaction log can be changed to suite us.
run dbcc loginfo(sagent_dev) display the followings:

Note that the virtual filesize can comprise of different configuration. In other database I can specify this logical size to whatever I like.

We would like to replicate from a SQL 7 DB some data onto a SQL 2000 Server running SQL 2000. We plan to take some data off the SQL 7 DB's and create a Data Warehouse on the SQL 2000 Box.
Question: Will the data replicate successfully from the SQL 7 box onto the SQL 2000 box?

Hi,
I am trying to disable transactional replication, but am having some problems. I used the wizard, however, it has taken 7 hours so far and is still not done. SQL Server (7.0) is showing the connection as runnable but it seems as if nothing is being removed. Am I missing something? Should I have done something else before running the wizard? I can't even kill the SPID.
Can anyone help or offer some advice?
Thanks in advance...
We're running Lawson software on our SQL 2000 box. We're using Veritas
Backup Exec to back up the databases to tape. I'm also using a Maint
Plan for an extra backup (kinda redundant, but I need the practice at
all this). I just added transaction logs to the maint plan (so I
thought) but I only see a log for 1 of the 3 databases.
Also, my trans log file is 11 gig. I thought backing up the trans logs
would get the trans to delete afterwards (databases are recovery
model=full). Can anyone point a newbie in the right direction.
Fortunately it's not in production yet, and we haven't had any disasters
(yet).
No I did not write this below, this is from a vendor, I used profiler and I believe their SP is causing a blocking problem on their vendor supplied DB. It thought at the least always have a begin end or a begin trans commit trans. ANy quick opinions greatly appreciated

Guys,
Should the transaction log of the system databases be backed up and if so, how often should this be done, generally?
Currently, we are backing up the system databases daily. The transaction log of the system databases, however, is not backed up.
Recently, I was wondering what exactly could happen, which would imply that we need to back up the transaction log of the system databases.
As far as I understand, 'msdb' contains things like jobs, dts. As such, if no jobs/dts are added in the middle of the day, there is no need to back up the trans log of this db - there could even be no reason, in such case, to back this db up at all!
'master' db would change if we add/modify objects/properties and so on ... so unless many changes are made, no need for backing up its trans log.
Having said that, could anyone enlighten me as to whether it is necessary to back up the transaction log of the system dbs and/or what it depends on and/or when it is suggested to do so?
Thanks you
