SQL Server Admin 2014 :: Append Differential Backup
Feb 10, 2015
Look at this scenario
1- I have created a backup device
2- I have created a maintenance plan full backup and run it - with overwrite option on the backup device
3- I have created a maintenance plan differential backup and run it with append option on the same file of backup device
4- I have created a maintenance plan log backup with append option on the same backup device
When I made restore database from the backup device i found three files the full and differential and log backup
5- I ran again the differential backup maintenance plan ( suppose to be ran everyday night )
when i made restore database I found only two backups the full and the last differential !!!
what I want to do is to take a full backup every week , append differential backup everyday and append log backup every hour
when I ran the last differential backup it erased the first differential and log backups, why is this happening and how to apply this scenario and keep the all differential backups on the same backup device .

I run the following:
EXECUTE dbo.DatabaseBackup
@Databases = 'F1SB',
@Directory = 'F:SqlBackup2014',
@BackupType = 'FULL',
@Compress = 'Y',
@Encrypt = 'Y',
[code]...
I cannot see the file created in the directory. The account under which sql server the agen job run have full privileges on it and is sysadmin.Then i run the Command in ssms
BACKUP DATABASE [F1SB] TO DISK = N'F:SqlBackup2014<server>F1SBFULLIGS-DB01_F1SB_FULL_20150510_214455.bak' WITH NO_CHECKSUM, COMPRESSION, ENCRYPTION (ALGORITHM = AES_256, SERVER CERTIFICATE = [serverCertificate])
and I get this error message:
Msg 3013, Level 16, State 1, Line 13
BACKUP DATABASE is terminating abnormally.

I need backup script to take all the database backups and we have the maintenance plan but our database character size is 98 and when we are taking the backups through maintenance plan while storing the backup history information it is adding the date and timezone information and exceeding the length to 128 so it is not writing the information on MSDB.
So we want to take the backup using the script and it has to create sub folder for each database. Also if any of the database fails it should continue with others.

I've got the below and have several variation and still cant seem to find a perfect way to query the server to bring back that last full backup per db. I'm shopwing mutilple records in the backup set db w/ type = 'D'. I look online and type D = Database. Which i assumed it meant full database backup. Apparently not. Try running the below on one of your full databases. Then check to see if the date is actually the last backup date.
DECLARE @db_name VARCHAR(100)
SELECT @db_name = DB_NAME()
-- Get Backup History for required database
SELECT TOP ( 30 ) s.database_name,
m.physical_device_name,
[Code] ....

Recently I have faced one DBA interview, below is the question they asked me.
" Does AlwaysON secondary replica support Full backup, if it is not why"?
I know AlwaysON secondary replicas support only copy_only and tlog backups, why they wont support full backup?

If data is modified (by an insert, update, or delete) while the backup is running, will the backup contain those changes or will it be added to the database afterwards?

With all the new functionality, can 2014 now restore a single table from a standard backup without using any third party tools? I have looked, but can't see this listed as a feature (though that doesn't mean it's not there, maybe I've just missed it).

I am planning to take one full backup and Transactional Log backups for every month ..as i will be making the changes in database only once in a month .
And I am aware of that in case of disaster i need to restore database with all the Transactional Log backups . My Plan is to have Transactional log backups for 5 Years and after 5 years i would be taking a full backup .
So should I need to take any other precautions or concerns with this approach.?

we currently use Backup Scripts from Ola Hallengren, It Says Full (non copy-only) and differential backups are performed on the primary replica. Full(Copy-only) backups and transaction log backups are performed on the preferred replica.
we currently do FULL(COPY_ONLY) Backup everyday and LOG Backups for every 15 min, is there any performance benefit on running the FULL (non copy-only) on the preferred replica .

I know that the performance of the database is bad if i shrink the database. What happens to full backup or transaction log backups?

What is the best way to restore a database from a folder of backups (including full, diff and log backups) without using the backup history in msdb?
I have a restore process that restores all backups on a regular schedule in order to fully verify their integrity. To do this, I use the backup history in msdb on each server that I'm monitoring. I had a thought the other day that I would be in trouble if I lost msdb. Then my backup history would only be as good as the last backup of msdb.
What I'd like to do is read a folder of backup files and generate a restore script up to a specified time. Would I use RESTORE HEADERONLY to do this? If so, would I use PowerShell to traverse each file in the folder?

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"?

I have an issue to restore an encrypted backup via GUI.I can restore an encrypted backup on another instance using t-sql command, but cannot do the same using the GUI of sql server 2014. The message error is: No backupset selected to be restored.I have restored the master key from the instance where the encrypted backup was created on the instance where I want to restore the encrypted backup, then restored the certificate. I managed to open the master key. I have the following versions:

I've a SQL server 2014 running on one of our server. We're in the process of implementing security steps for our databases. I've encrypted a column in one of the table in the database on the server. The issue is when I restore the backup on my local SQL server and run a query to decrypt the column data it gives me null values. On the other end when I decrypt the column data on the main server it works fine. I found a thread on this forum which states to do the following when restoring the encrypted database on different server.
USE [master];
GO
OPEN MASTER KEY DECRYPTION BY PASSWORD = 'StrongPassword';
ALTER MASTER KEY ADD ENCRYPTION BY SERVICE MASTER KEY;
GO
select File_Name
, CONVERT(nvarchar,DECRYPTBYKEY(File_Name))
from [test].[dbo].[Orders_Customer]
I tried doing above still no luck.

I did tried the encryption on server "A" for database "AdventureWorks2012". Then I tried to restore to server "B". There was the certificate issue, and I thought "of course : it's encrypted ! Let's deactivate it". So here I go "ALTER DATABASE AdventureWorks2012 SET ENCYRPTION OFF".I look at sys.databases : not encrypted.I backup using no encryption, I verify using msdb.dbo.backupset : not encrypted.
I move my backup to my other server where encryption was never configured (so no certificate, nothing...), and I have the error :
Msg 33111, Level 16, State 3, Line 1
Cannot find server certificate with thumbprint '0xFA130E58C999C4919B8975999C83A75A403B11D8'.
Msg 3013, Level 16, State 1, Line 1

I want to set up a database role so that users can use sp_readerrorlog through SSMS. It does a check on membership in the securityadmin role.
I have tested it and can see you can grant execute on xp_readerrorlog but the SSMS GUI uses sp_readerrorlog.
I thought I could create a user/certificate and add the signature to sp_readerrorlog but it's not permitted (likely because it's not a normal database object).
So the other solution is to add the users to the securityadmin role but then explicitly deny alter any login (best done with a custom server role in 2012+ but otherwise just manually in 2008). I tested this out and it works, I'm not able to alter any logins or increase my own permissions, I also did a check of what's reported from fn_my_permissions(null, null) and it shows minimal permissions like I'd expect.

JOIN TABLED AS D ON D.FK_PERMISSION_REF = C.PK_PERMISSION_ID
JOIN TABLEE AS E ON E.PK_PERSONNEL_ID = D.FK_PERSONNEL_REF
WHERE A.[OBJECT_NAME] = 'MyObjectName'
It's not working. I'm getting:

What I'm looking for is:

Hello,
I'm trying to run a differential backup on our new 7.0 box. It fails with an error message number 3242 "The file on Device 'E:MyFile' is not a valid Microsoft Tape Format backup set."
Why "Tape Format" if I said "Backup database [mydb] to disk"?..
When I run exactly the same query without "Differential" I got a full db backup.
Am I doing something wrong?
Thank you,
Anastasia.

Hi,
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

We have a 1TB Database. Our backup strategy looks like this.
Weekly Full backups - Saturday 10pm. (Takes anywhere between 5 - 9 hours)
twice Nightly Diffs (8:30p and 2:30am - Mid week this takes roughly 1.5 hours)
Hourly Log backups starting at 4:00am until 11pm.
I have an issue where I need to restore to 3:00 today. If my (2:30a)Diff is still running at that recovery point.
I am getting an error when trying to restore Full/2:30a Diff/4a Log with a stopat 3:00a.
Error telling me my log backup is incorrectly formed.
Can I, in fact, restore to this point at all? Do I need to go back to my previous Diff (8:30p) and restore the logs, if so, which ones?
My nighttime Diff ran from 8:30 - 10p.
I have logs at 9p, 10p, 11p, 4a

Using Ola Hallengren's scripts I do a full backup of a database on a Sunday. Then differential backups every 6 hours and log backups every hour. I would like to keep a full week of backups based off the full backup done on Sunday. Is there a way for me to clear out the diff and log folders after the successful full backup on Sunday nights?

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...

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.

Hi
Is there anyway I can implement a standby server in SQL Server 6.5 ? In addition are there any tools in the market which I can use to perform a differential backup ?
I believe SQL Server 7.0 can do this, will I be able to use ARCserverIT or seagates's backup exec to perform these functions ?
Vijay
