Jul 20, 2005If a full backup kicks off at 6pm within SQL Server, and takes 2 hours
to complete, will transactions between 6pm and 8pm be included in the
backup?

SQL Server 2005 Full/Differential Backup Issues
Jun 29, 2007Hi,
After some advice - I have a SQL Server 2005 database which is part
of an anti-virus setup. The main database is 25Gb is size, and it
is running in simple recovery mode. There are two backup jobs in
place, one to do a differential backup each Mon-Sat, and one to
do a full backup on Sun. Although the backups do get done they
are taking 5 hours to do. Any wiz out there care to suggest what
the problem is, I would've though that maybe an hour was more
acceptable ?
Cheers,
Gordon

Would the transactional log backup with out a full backup after the restoration of a database be valid?
View 5 Replies View RelatedRecovery :: Differential Backup Much Larger Than Database / Full Backup
Nov 16, 2015I 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...

View 2 Replies View RelatedProper Way To Truncate Log After Performing Full Backup (SQL Server 2000)
Jan 29, 2007Hello 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...?

Does A Full Backup Include Data Changes Made During The Backup?
Nov 29, 2007If 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,

Differential Backup Fails Because Of Erroneous Full Backup
Jul 19, 2007Hi
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, 2007Hello,
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.

SQL Server 2008 :: Test Backup Restores (full And Log) - Restore Databases Automatically?
Apr 4, 2015I am working towards automating the process of testing our backups. For the meantime, I do it all manually - I copy the backup files (full + transaction logs) to our test server and then run the restore script. Once database restored I run the DBCC CheckDB. The results of checkdb I manually upload to our Sharepoint portal as proof that the backup file is intact with no errors.
here are some ideas I have but have not yet tested:
Create a maintenance plan with each 3 jobs:
--> Powershell script to copy the files from Prod server to Test server - add this scrip to Job1
--> Powershell script to restore databases files - add this script to Job2
--> Run the DBCC in powershell (yet to find if possible in PS) - add this script to Job3
I would like to use seperate jobs as to get a report on the duration and status of each job
Would also like to get the results of the DBCC Checkdb as proof that no errors were found for upload to our Sharepoint portal. Dont know if possible via the job.
Should Full Backup And Transaction Backup Be From One Plan?
Mar 11, 2008Hello, 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

Differential Backup Not Smaller Than The Full Backup
Jun 6, 2007Hi,
Using SQL Server 2005, we have a 2.8Gb database under the Simple recovery model. The database contains ~50M rows and each night ~60k rows are loaded(appended) to the database by a SSIS task.
We configured a Maintenance Plan which is executed once a week to perform a full backup of the database. The resulting backup file is ~2.8Gb, as expected.
We also configured another Maintenance Plan which is executed every day, a few hours after the SSIS task is executed, to perform a differential backup. To our surprise, the resulting backup file is about the same size as the full backup, ~2.8Gb when it should only be a few MB (only 60k rows are added to the database)
When we launch the "Restore Database" wizzard we clearly see the different backup set, Full and Differential but they all have about the same size (same for the physical backup file on disk).
Is there anything we are missing, why are the differential backup that big?
Thanks for any advice.

View 1 Replies View RelatedFull Backup And Tran Log Backup
Jun 14, 2007Hi:
I have 30 databases on sql server 2005 that I need to do a full backup every morning at 7:00 and tran log backup every 30 minutes until 7:00 PM. If I create a maintenance plan for a backup using the wizard I have the option of starting a full backup at 7 am and then an option of doing tran log backups every hour using a different schedule. I plan on selecting the option to create a different folder for every database. I just need to confirm that in this way the way to restore the data would be
1. to restore a full backup
2. apply all the tran logs depending on the time they want to recover back to.
I just think this is the easiest approach to have 30 databases on the same backup scheme instead of creating a separate backup device for each database and doing a full backup on that device and appending all tran logs to that device which means just 1 bak file versus the above strategy with a number of tran log files. Please advise.
Thanks

I have 1000's of table in my database. Manually doing so is not possible.

Transaction Log Needed When Full Backup Is Done?
Apr 30, 2008Please correct me if I am wrong with this:
I am using SQL Server 2000, when I do a backup I use the database maintenance plan at enterprise manager. I select my database and then I schedule the complete backup and transaction log backup to "everyday at 22:00:00"
My question is, do I really need to do the transaction log backup? If I am not wrong with the complete backup I can already recover all my data, the transaction log backup is useless if done at the same time that I do the complete backup, right?
Backup And Restore(full + Transaction Log)
Mar 10, 2008I have this database "DB1" which is in FULL recovery mode.
I run full daily backup -Monday to Saturday
DB1_Mon.bak
DB1_Tue.bak
DB1_Wed.bak
DB1_Thur.bak
DB1_Fri.bak
DB1_Sat.bak
Come Sunday - for the first time I have run transaction log backup.
DB1_Sun.trn
And now, I need to restore DB1 - but the only full backup that I have is the Monday - "DB1_Mon.bak"
Is my database complete if I restore only "DB1_Mon.bak" plus the "DB1_Sun.trn"?

Simple Recovery And Full Backup
Jun 10, 2006Hi MVPS/MS Experts:
Pardon me and my ignorance for asking this question. I just want to understand the backup architecture more clearly. According to BOL (both in SQL 2k and SQL 2k5) in simple recovery mode trasaction log backup is not possible since the log is truncated on checkpoint which is true. Also we know that FULL backup backups both the db and transaction log as well.
My question is what happens when a database is in simple recovery mode and a full backup is done. since the tran log cannot be backed up does only the db backup is done when a full backup is done?. What exactly happens behind the scenarios?. Is it that only the active log gets backed up when a full backup is done in simple recovery mode?. I am trying to understand how a full backup in simple recovery mode behaves without contradicting the full backup architecture and that the veracity of the statement (both db and tran log backup in full backup mode) holds true for a simple recovery scenario.
MVPs/ MS Experts if you could Please explain it in detail, I would really appreciate it.
Thanks
