I have a MS SQL 2000 dB that is 3GB, the transaction log is about 2GB.
I do a full dB backup every night. My question is, shouldn't the
transaction log shrink down to next to nothing after a full dB backup?

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?
View 5 Replies View RelatedHello, 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

what is the differences between a differenctial backup and transaction log backup?
View 1 Replies View RelatedI 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!

Hello!
We have unusual situation. We increased the size of transaction log up to 100MB.
After we run the transaction log backup the physical size of transaction log file getting smaller and smaller from 100 to 88 and then to 76 and so on.
Do you now the reason?
Thank you,

I have a very serious problem, if somebody can help me quickly. my transaction log file is getting bigger and bigger even after truncating. today morning when i checked, it was 1.5 GB, by evening it has gone upto 3GB, the total size of the database is 3.4 GB, out of which 3GB is Transaction log. why is it growing heavily!!!!!!!!. there is not much transaction happening. even after truncating the transaction log it is still showing 3gb.
help!!!!!!!!!!!!!!!!!!!!!!!!!!!!
I currently have an database that is 110 mb and grows on an average of 5mb a week. THe enviornment is IIS 5.0 /ASP /SQL 6.5. However I find myself continously increasing the log file since it frequently fills up. At this point it is 300mb and can be filled in less than an hour with an average of 35 users. I realize that this file has alot of overhead and is affected directly by the application making the updates. Last week on a busy day (time card app) I witnessed the log increase from below 75% to 100% in a minute, forcing me to truncate the log. This application is an administrative nightmare! Any ideas what could cause this type of activity in the trans log.

We have here a small database (around 400 MB) with simple recovery. Also autogrowth is active.
But why does the transactionlog also sized up, when it is not in use?
Our TL is around 100 MB and filled with 5 MB.
Everytime the DB gets bigger, the TL also....
This isin continuation with my previous query. If i cannot reduce th T Log size , how can i stop it from increasing further. Can i make secondary log files which can be deleted later on?

I need to create a script that would return the size of transaction logs for all databases. I ran a select statement against the sysfiles table but you can only run it against one db at a time. Any suggestions?
Thanks.
Hello dear friends,
In my database i am not able to take the backup of transaction log.
Even if i took the back up and then shrunk the file it doesnt make any change to my transaction log size.
Still the size is same.
So in every two weeks i am restarting my server.
Once it is restarted then it is ok for another 2 weeks.
After 2 weeks my transaction log size will be more than the size of my datafile.
Can you suggest your openion.
No replication or log shipping exist.
Thank you

Hello, everyone:
I am deisgning the transaction log file, and having the rough idea for transaction numbers per hour. How to determine each transaction size?
Thanks a lot.

I have written an application which runs as a windows service. The application constantly requires to write data into the database.. pretty much every seond. Some of the tables have more than 800,000 rows.
the application works fine. Hoever I am noticing the transaction log grows very fast. All information added is handled through stored procedures. In one week the transaction log grew to 2GB. I assume a part of the reason was because I ran out of disk spae once. But generally this transaction log is growing fast. What could cause the transaction logs to grow fast, What could I do to keep the log file size down....I cant have the database down as the application needs to be running constantly.
I have a database whose recovery mode is FULL. I setup one maintenace plan do a backup for the database and another backup plan which backup the transaction log. The two maintenace plans runs daily.
However, the log file is still growing to a very large size. Should the log file be able to reuse after each backup of the transaction log ?
If I'd like to keep the database recovery mode as "FULL", what do I have to do to keep the transaction log within a reasonable size.
How the size of transaction file is calculated. are there any standards.
I created my database with 2000 mb data filesize and 200 log file size.
now my datafile size has reach to 11000 mb but log file size is still 200.
Therefore when I take the online backup my logsize totally consumed and I have to cancel my backup.
Please reply ASAP.

If I have a transaction log in a database of size 1GB ( space allocated is during creation of database) currently only 300 mb of its space is used i.e. nearly 700 mb is free. If I want to reduce physical file size of transaction log by 200 mb and release it for operating system then How can I do it???
View 4 Replies View RelatedHi,
I'm sure this question has been asked before but I need clarification on a couple of points.
I have a database (500 Mb) which is having a full backup every night at 2AM. I am doing a transaction log backup every 2 hours between 7AM and 7PM. I have noticed that the transaction log keeps growing bigger and bigger so I do a manual truncate.
- Will my transaction log keep growing bigger and bigger ?
- How can I automate a task to reduce the log size ?
- Does a full backup not truncate the log ?
Thanks for any advice,
Tim
I created a database and had its file size as automatic grow. Now the database file is of 17 MB and its transaction log file size is 230 MB. After checking transaction log file properties I came to that it is using 13 mb only and the rest of the 230 MB i.e 217 MB is free. I want that area in the transaction log to be freed and get the transaction file size to its actual size. Any help will be greatly appreciated.
Thank you in advance.
P.S: It is very urgent.
My database's transaction log has become 1.7 GB. Can I reduce it's size? I have tried to shrink database and also set truncate on checkpoint option and also taken the backup after that. but nothing helps. Please advice.
View 1 Replies View RelatedHi,
A very quick (and probably simple to answer) question.
I have a database for which I used Enterprise Manager to set up a complete backup at 2AM every day and a transaction log backup every 2 hours between 8AM and 8PM.
I have noticed that the transaction log is growing huge but I thought that it is supposed to get truncated every complete database backup !!
What can I do to "manage" the log file size ? (preferably automatic task)
Thanks,

Hi !
How can I find or calculate the exact space occupied by the database and transaction log in the hard disk?

How do you reduce the file size of the transaction log? Is it safe to delete the transaction log? I tried clicking on the ellipse (...) box in database properties, but even tho i'm the dba, it says i don't have permissions to do that! I see the "automatically grow transaction log" and "maximum file size for transaction log" dialogs, but our transaction log is already 5.5 GB, and we need for it to be WAY smaller! Is there a way to back it up, then start over with a new one or something?
DB data file size: 200GB
giant table A: 100GB
Sometimes we've had to do ALTER TABLE statements on giant table A such as converting from int to float that ballooned to using 200+ GB of transaction log to make a copy of the table with the new field type, copy the data in, rename and delete all in a transaction. So we ended up with a 250 GB log file that sits around being 98% empty most of the time as we do log file backups every 3 hours. This seems like a waste of SAN space, however there are times when we do need to do a conversion and we need the space available so it stays. Using a local hard drive for extra log space I would think would severely slow down the conversion. So how do most people handle this. Perhaps have a temp drive tray plugged in just for conversions shared by the data center? Any other suggestions?
I'm thinking we really only need the log file to be big enough to do all the index maintenance day to day and only grow it large when we know downtime and a conversion will be going on. Growing a log file to 250GB is time consuming in itself. No instant initialization of log files in SQL 2005.
Hi,
Currently my db size is only 6 GB but the transaction log file initial size was set to 20 GB and has grown much way beyond the db size with the autogrowth feature turn on. The database was originally a test/development DB and was migrated to a production server including the log file. This probably caused the accumulation of transactions on the log.
We run backup everyday and tried to shrinkfile and file size did not change.
Can I change the "initial size" setting of the transaction log without causing any problems? Do I need to stop the service before I made the change assuming I made the change after the backup run? Or can I change it on the fly?
Thanks in advance.
We have a database that is backed up every night (full backup). The database size is around 5GB and the transaciton log is about 3GB. And it's 3GB after the backup too. I thought the log size should shrink after each full backup. I can't imagine what data the log needs to maintain after a full backup is complete.
What can be done about this large transaction log?
TIA,

Hi,
How can I increase the transaction log size of my sql server 2005 database? i can execute the shrink and backup log which can shrink the .ldf file to 1MB. However, since my dts involves a lot of inserts and updates, the my transaction log grows to 700MB in the middle of my dts execution. How can i increase the transaction log size maximum capacity to probably 1.5GB just so it can accommodate my full dts execution?
BTW, this is my commands to shrink the log file:
DBCC SHRINKFILE(<dbname>_log, 1)
BACKUP LOG <dbname> WITH NO_LOG
DBCC SHRINKFILE(<dbname>_log, 1)

Hi,
Database transaction log file has reached to 1 GB and (99% of this space is free). When try to reclaim the unused space, I have no luck. Initial size of the transaction log has now reaches 1GB. When trying to change the initial size to 5 MB, it does not work.
I have backup the transaction log with Truncate the transaction log but system is no releasing the space.
Please Guide.
Thanks

Why is it that lately our full backup (.bak) file size is more than 2x the size of the actual database file size (.mdb)?
View 9 Replies View RelatedCan anyone help me reduce a transaction log. It is currently at 2.5GB because it was set to autogrow with no backup !?
I need to drastically reduce it and have backed it up and tried dbcc shrinkfile...but...it now says space used is 120MB but current size is still 2.5GB.
How can i reduce this down please ??

hi, i'm a newbie in SQL Server and have recently setup a test SQL 7 server. I used all the defaults at the beginning, and now the MDB file is about 500MB and the LDF file is of similar size.
i'm still trying to figure out how to reduce the size of the transaction log file. Currently I only have full backup of the database once a week, and there is no backup for transaction log.
as of this moment, the transaction log is of not much use to me, but I really want to get it reduced as i'm running out of disk space.
and i'd also greatly appreciate if someone could suggest a good DBA practice on the proper setup/handling of transaction logs (how to balance the disk-space usage AND be able to use the transacton logs for proper roll-over during a recovery process).
i'd soon be setting up a SQL 7 server where about 10 active users are expected at any one time. I've read that the transaction log file should be about 40% to 50% of the estimated size of the database file, and should be allowed "auto-grow". So what happens if the more space is required by the transaction logs? Does a full-backup purge the transaction logs (like the way they do in Exchange Server)?
Thanks!
