Transaction Log Backup On Server With Less HDD Space

Nov 29, 2007

Hi,

I started working in one company as a DBA where the Ex-DBA left the company long time back. So all the databases have huge transaction logs (50-80GB) in size. But the problem is-
1. HDD space on the m/c its only 45GB. When I ran TLog backup cmd on that m/c, the hdd space was started reducing around 1GB/min and in few minutes I saw hdd space left is only 15GB so I stopped cmd (It had completed only 37% of the backup).
Second time again I tried to take TLog backup on hdd placed on n/w path but again I saw it was eating local disk space very fast.

So my question is, Is it like when you take Tlog backup of size say 80GB it will use 80GB local hdd as a temporary storage?

2. For this I found 1 workaround- I took Full backup then I restored it on some other m/c, then shrun the log files to few MB's then I again took Full backup of this shrunk db and restored it on production.
Is this only solution to my problem(Very less space on production's local HDD)? If anyone knows better soln than this then plz suggest me.

Thanks in Advance.

Problem With Space Allocated For Transaction Log Space

Dec 5, 2001

Hello,

Somebody know how to reduce the space allocated for the transaction log space for my SQL_DB ?

3700 MB allocated but only 100 MB used and 3600 MB are free !

Transaction log properties :
Automatically grow file are filled
file growth by percent = 5%
maximum file size - restrict filegrowth = 3700 MB (we can't reduce it !)

Thank you for your precious help !

Required Free Disk Space For SQL Server Backup Operations

Feb 4, 2008

What is the percentage of FREE disk space that is needed for a backup? I have backups that are failing with no disk space errors. But there is enough disk. Does SQL Server need a percentage of free space all the time?

Thanks

SQL Server Admin 2014 :: Unable To Access Physical Server To Backup Transaction Log

Dec 5, 2014

I've recently started working with a public sector organisation who have 4 clustered sql instances that has 80% of it's db mirrored.

Looking at the transaction log - it seems that a transaction log backup is a good idea as the log is 4x larger than the data file.But I'm not allowed access to the physical server to check onto which drive I can create the trn. No RDP, no vmware - let's be honest I'm not even allowed to launch cmd line Also the Server Manager informs me "We will need to carefully look at database backups if you guys want to start doing these backups on box, as that will break our off box backup routine (it will screw the transaction chain)."

I don't understand how backing up the transaction log could break the "transaction chain"?

Transaction Log 73.6% Space Used

Feb 20, 2001

Hi Folks,

It has come to my attention recently that my Transaction Log 200MB and a 1Gb Data Device has gotten much bigger than it used to be after
I deleted several thousand rows of data.
It used to be under 5% space used and now has settled at around 70 % space used. I have dumped the transaction log with no_log and done
backups immediately after on several ocassions and this has not solved the problem. I have also increased the log size from 150MB to 175MB
but this does not seem to have solved my problem.

Anyone got any ideas on how to decrease the % used log space in the Transaction Log ?

Is it bador unwise to have so much of the Transaction Log space used up ?

Thanks in advance,
Alan

SQL Server 2000 - Run Transaction Log Backup Using Windows CMD File

Mar 19, 2007

How I can run a SQL Server Transaction Log Backup using a Windows CMD File.  It's that posible?  Anyone know the command or how do this?

We already have a application monitoring our SQL databases.  Everytime the transaction log get full, it sends us an alert.  Would be better if our application repair the problem itself, executing a command (Windows CMD File).

I'm not a expert using SQL databases or MS DOS Prompt commands.

Any help will be appreciate.

SQL Security :: Full Backup Needed After Restoration Of Database Before Transaction Log Backup

Jul 15, 2015

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?

Transaction Log Space To Large

Feb 24, 2000

I am new to SQL and might be missing something very easy. I have a situation where the space allocated to the transaction log of a database is extremly large (5 Gig). I can not manually reduce it. This gives me a "Error 21335: [SQL-DMO]The new DBfile size must be larger than its current size." This is a problem because the increase in size has taken all available space on the server.

How Much Space Used In Each Transaction Log File

Mar 22, 2007

Is there a way to know how much space is free in each transaction log file of the same database?

Example:

A database with 3, 1GB files for transaction log: A, B and C created in this sequence.

From what I have read, since SQL Server 2005 writes to a single transaction log only, I guess if the transaction log is using 2.5GB than A and B are full and B is only half full. Is this correct?

Thanks.

Why Does Database Need Minimal Space In Transaction Log?

Jul 27, 2000

The transaction log takes up a lot of space on my database, and even after I try truncating the log, doing a transaction log backup, and then shrinking it, I am not allowed to reduce the size of the transaction log to less than 250MB. Is there some reason why this space is required?

Should Full Backup And Transaction Backup Be From One Plan?

Mar 11, 2008

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

Is It Possible To Restore From A Database Backup Without A Transaction Log Backup?

Oct 14, 2007

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!

today I've put in production a big database accessed by 200 concurrent users, this database has READ_COMMITTED_SNAPHOT set to ON.I know that RCSI set to ON is very aggressive on tempDB so I'm monitoring it.I've noticed that the Transaction log space usage (%) on TempDB is slowly but ever increasing, I mean in the last 24 hours I've started from a 99% space free, now we are 37% space free...is it normal? TempDB log is 35GB in size.

Problem Backing Up Database And Transaction Log Due To Disk Space Limitations

Jul 23, 2005

I am having a problem backing up my database and TLog files due to alack of local diskspace. The db file is about 30GB and the TLog isabout 20GB each on a different hard disk. Each disk doesn't haveenough available space to accomadate a backup. I also can't shrink thefiles because part of that procedure would require a backup.Question: Can I use a redirected drive for the backup media? Is therea way to trick SQL into allowing this? If the answer is no, doesanyone have a suggestion as to want I should do? I am in the processof requesting more disk space,but that could take a while.Thanks,

Backup Failing, Plenty Of Disk Space

Jan 4, 2008

Good morning,

We get frequent (1 out of 3) "sqlmaint.exe failed" errors during backups for one of our larger databases (40GB). So i removed the maintenance plan and put in a custom backup job to get a better error msg in the log:

BackupMedium::ReportIoError: write failure on backup device 'F:MSSQLmydb_2008_1_3_21_45.BAK'. Operating system error 112(There is not enough space on the disk.).

However, we have PLENTY of space on disk:
LOG DISK - NTFS - used space = 2GB, free space = 81GB
BACKUP DISK - NTFS - used space = 29GB, free space = 82GB
So even if it doubled in size, there would still be 50GB free.

Any ideas?
Thanks!!

Transaction Log Backup

Sep 18, 2001

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

Transaction Log Backup

Jun 9, 1999

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

Transaction Log Backup

Feb 21, 2001

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

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.
