Veritas Backup Very Slow

Jan 28, 2004

Hi,

The last five days, the SQL Server Production backups to tape have been incredibly slow. Actually, they don't complete because they have been going on for 60 hours. Everything on the servers (clustered production environment) seems fine. Nothing untoward unusual. Any ideas what could be causing it? We're thinking of rebooting tonight.

Any help would be appreciated.

Backup Slow Throughput

Nov 16, 2006

Hi Team,

I have a SQL 2000 instance with 46 Databases (all databases put together will be 15 GB in size). I am running a SQL Backup using a third party software.

My full backup of the SQL instance which backs up 15 GB of data finishes within 30-45 minutes. But, my differential backup of the same instance which backs up only 150 -250 MB of data takes 12 hours to backup.

I found a knowledge article from MS Support site which says, differntial backup would take more time than full in few scenarios.

http://support.microsoft.com/default.aspx?scid=kb;en-us;196658

But the above document is for SQL 7.0. Will it be the same for SQL 2000 and 2005 too? If yes, can you please tell if I can increase the speed of differential backup in my environment. Should I modify any SQL Parameters?

Please let me know your thoughts on this..

Thanks
Santhosh

SQL 2012 :: Slow Backup On HA Secondary

Nov 2, 2015

2 Boxes in HA, identical hardware (VMs) and both utilising identical storage systems (Nimble SANs).Was needing to do a copy only backup of a few databases for an escrow environment we have, so decided to perform this on the secondary box.Small ~10GB ish database first, seemed to be really slow, so opened resource monitor and noticed that disk read / write was getting limited to about 15MB/s so took a little while (the big one is over 1TB)

Tried this again on the primary it was done in seconds disk rate in the order of 250MB/s (same settings re compression etc).. I decided to make a copy of the backup file on the secondary, the copy disk to disk went in the region of 150MB/s , so it appears that SQL Server is the bottleneck?

BACKUP LOG Cannot Be Performed Because There Is No Current Database Backup. BACKUP LOG Is Terminating Abnormally.

Jan 31, 2008



Hi there

I'm getting this message on my third automated backup of the transaction logs of the day. Both databases are in full recovery mode, both successfully backed up at 01.00. The transaction logs backed up perfectly happily at 01:30 and 05:30, but failed at 09:30.

The only difference between 05:30 and 09:30's backups is that the log files were shrunk at 08:15 (the databases in question are the ones that sit under ILM2007, and keeping the log files small keeps the system running better).


Is it possible that shrinking the log files causes the database to think that there hasn't been a full database backup?

Thanks

Jane

SQL 2012 :: Error (backup Failed To Complete The Command BACKUP LOG) In Event Viewer

Aug 23, 2013

On the SQL Server the Event Viewer shows the same messages and errors every evening between 22:05:00 and 22:08:00. The following information messages are shown for every database:

"I/O is frozen on database <database name>. No user action is required. However, if I/O is not resumed promptly, you could cancel the backup."

"I/O was resumed on database <database name>. No user action is required."

"Database backed up. Database: <database name>, creation date(time): 2003/04/08(09:13:36), pages dumped: 306, first LSN: 44:148:37, last LSN: 44:165:1, number of dump devices: 1, device information: (FILE=1, TYPE=VIRTUAL_DEVICE: {'{A79410F7-4AC5-47CE-9E9B-F91660F1072B}4'}). This is an informational message only. No user action is required."

After the 3 messages the following error message is shown for every database:

"BACKUP failed to complete the command BACKUP LOG <database name>. Check the backup application log for detailed messages."

I have added a Maintenance Plan but these jobs run after 02:00:00 at night.

Where can I find the command or setup which will backup all databases and log files at 22:00:00 in the evening?

SQL Server 2008 :: Backup Running Long And Backup Threads Show Suspended

Feb 18, 2015

SQL Server 2008 r2 - 6 GB memory...I attempted a backup on a 500GB database but it was taking way too long. I checked the resources on the box and saw the CPU at 100%. I checked the SQL Server activity log and saw a hung query (user was not even logged on) that had multiple threads so I killed it and now the CPU utilization is back to normal.

Trouble is, now all of the threads in the activity monitor for the backup show 'suspended' and the backup appears to be not doing anything.

SQL 2012 :: Backup Cleanup Of Differential And Log Backups Based On Full Backup?

Can Windows 2003 Server Backup Utility Be Used To Backup A SQL 2000 Dbase

Dec 28, 2007

Windows 2003 backup utility uses the shadow copy option that allows it to copy open files.
Therefore, can I use this utility to backup the .mdf and .ldf files for my SQL 2000 database?
I can then attach the .mdf files if I need to restore the database to another server.
Can anyone tell me if this is safe? I've tried it and it worked but I'm worried there maybe some lurking danger in using this approach.

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?

Recovery :: Differential Backup Much Larger Than Database / Full Backup

Nov 16, 2015

I have a database that is just over 1.5GB and the Full backup that is 13GB not sure how this is since we have compression on for full backups and my other full backups are much smaller than there respective databases...Now my full backup is taken every Sunday night and the differentials are taken every 6 hours after the full backup. Now I have been thrown into this DBA role with little to no experience just what I have picked up and read. So my understanding of backups are limited but what I think I understand is that we take a full backup and the differential only captures what changes in the database so my question is why is my database 1.5GB but my differential is 15.4GB? I have others database that are on the same instance and don't seem to have this problem. I also just noticed that we do not rebuild the index before a full backup like we do on other instances...

Newbie Question Regarding Backup Device And Backup Foile

May 10, 2001

This is probably a simple question but I have to ask it anyway. When backing up I can backup to a file on my local drive but I also can create a device to the same location on my local drive. Is this doing the same thing. If I so desire to backup to the local drive(bear with me) what is the difference between creating a device and a file called mybackup or just choosing to backup to a file called mybackup? Should I always create a device? I know these are dumb question but....

Does A Full Backup Include Data Changes Made During The Backup?

Nov 29, 2007

If my backup starts at 8PM and take 1 hour to complete, will the changes made to the database during that hour be captured in the full backup?

Stated another way, will my backup be a snapshot of:
a) 8PM when the backup started
b) 8PM with some of the changes made between the hour
c) 9PM when the backup finished?

Anybody know the exact way SQL Server handles that logic?

Thanks,

Marc

Differential Backup Fails Because Of Erroneous Full Backup

Jul 19, 2007

Hi

I am using the Simple recovery model and I'm taking a weekly full backup each Monday morning with differentials taken every 4 hours during the day.

On Wednesday afternoon, a programmer ran a process that corrupted the db and I had to restore to the most recent differential. It was 5pm in the afternoon and a differential backup had just occured at 4pm. No problem, I figured.

I restored the full backup from Monday morning and tried to restore the most recent differential backup. The differential restore failed. Since I had used T-SQL for the initial attempt, I tried using Enterprise Manager to try again.

When viewing the backup history, I see my initial full backup taken on Monday plus all the differentials. BUT, on closer inspection, I noticed another full backup in the backup history that was taken early Tuesday morning. I can't figure out where this Tuesday morning full backup came from. It wasn't taken by me (or scheduled by me) and I'm the only one with access to the server. My full backups are usually named something like HCMPRP_20070718_FULL.bak. This erroneous full backup was named something like HCMPRP_03a_361adk2k_dd53.bak. It seemed like it was a system generated name. Not something I would choose. To top it off, I could not find this backup file anywhere on the server and when I tried to restore using this full backup, it failed.

Does anyone have any clues as to where this full backup might come from? Does SQL Server trigger a full backup on its own if some threshold is reached?

I ended up having to restore using the differential taken just before this erroneous full backup and lost a day of transactions.

Any insight is greatly appreciated.

How Can I Trigger Full Backup On Tran Log Backup Error?

Aug 8, 2007

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.

How To Restore A Database From Backup With A Splitted Backup File

Apr 1, 2008

I should restore a SQL Server 2005 Database from backup. The backup contains three files, named user.bak0, user.bak1 and user.bak2.

How is the syntax of the restore filelistonly and the restore database ... ?

I usualy write
restore filelistonly from disk = 'path and filenam.bak'
restore database. zy
from disk = 'path and filename.bak'
with replace,
move.....
move....

This works but I cannot use it with a splitted backup file. The files are much too big to put together to one file.

Thanks in advance for any help.

Is There A MS SQL Backup Tool That Will Zip Or Compress The Backup Files?

Feb 27, 2007

Currently we use a SQL maintenance plan to do a full backup of all our databases daily (about 40 databases on our production server).  As you can imagine, this eats up disk space quickly so currently we manually zip the backup files and/or move them to an archive drive.  I considered writing an application to walk through the backup folder structure and zip any .bak file it finds, but I know there are some third party tools out there that will backup/restore a MS SQL database.
I was wondering if any of these also zip the backups once they are created.  Any recommendations or suggestions are welcome.

SQL Server Backup And Third Part Backup Tool

Oct 2, 2001

SQL 7.0 SP1.
We do SQL Server backup and also third part backup (with SQL agent active) of SQL Server databases.
Sometimes happen this situation:

01.00 SQL Server backup of DB1
01.00 third part backup of DB1
02.00 SQL Server T-LOG backup of DB1
03.00 SQL Server T-LOG backup of DB1
03.30 SQL Server differnatial DB backup of DB1
04.00 SQL Server T-LOG backup of DB1

or this situation:

01.00 SQL Server backup of DB1
02.00 SQL Server T-LOG backup of DB1
03.00 SQL Server T-LOG backup of DB1
03.10 third part backup of DB1
03.30 SQL Server differnatial DB backup of DB1
04.00 SQL Server T-LOG backup of DB1

My questions now are:
Are my SQL Server backups valid (DB,Differenatial and T-LOG)?
In case of a restore operation, can I use my SQL Server backups without problem?
In other words, can we leave the third part backup tool active or it should be taken away?


Can anybody clarify this for me?
Thank you in advance.

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.
