I would like to know what happens if i shrink the database with truncate only option and do a full backup or transaction log backup ? are the full backup or transaction log backup valid? I know that the performance of the database is bad if i shrink the database. What happens to full backup or transaction log backups?
View 9 RepliesI have a database that I am trying to recover space from, it consists mostly of unallocated space, but I can’t seem to get that unused space released.
Database size: 40,245.13 MB
DatafileMB: 38,063.63, DataAvailableMB: 37,085.15
LogfileMB: 2181.51
Sysfiles shows:
fileidgroupidsizemaxsizegrowthstatusperfname
114872144-112820SomeDB
202792332684354561010486420SomeDB_log
The DB is in simple recovery mode. There are no open transactions (used dbcc opentran).
The server is running SQL Server 2014 and the DB is in compatibility mode SQL Server 2008 (100). It was upgraded to 2014 a month or two ago.
I have tried to re-size the log to 100mb, but any way I have tried (none gave errors), the log file remains the same size. I have tied to shrink the log file (through the UI and via DBCC commands) without success; no errors, but also no change in file size.
I have checked Log Reuse Waits, just in case, and as expected it showed “NOTHING” (select log_reuse_wait_desc, name from sys.databases)
I tried running a checkpoint, but that did not allow any resize or shrink to work.
I have tied creating large transactions to move the used point in the log file, in case this was the issue. I did this by creating tables that I drop after large inserts. While it shows me that the log space % used increased, the log file still does not allow the space to be reduced.
The following is what I was using for the transactions to get the log used.
BEGIN TRAN
select a.* into testtable from sysobjects a, sysobjects b, sysobjects c
ROLLBACK TRAN
Each insert creates 93,576,664 rows.
Running dbcc SQLPerf(logspace) :

02114373427211437424645701280
Do I just need to continue running large transactions until the log space used gets high enough to get the “end point” in the log to really move? Is there an easier way to accomplish this (I have several DBs that have the almost identical problem), what I am using moves the Log Space Percent Used about a percent on each execution.
is there a way to backup all stored procedures in a database?

View 1 Replies View RelatedI 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 :

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 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.

View 5 Replies View RelatedIs there a way to backing up SQL DB without having to stop users from connecting to it.
View 5 Replies View RelatedLook 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?

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 .

View 2 Replies View RelatedI'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.

View 3 Replies View RelatedQuery to show logins that don't have any permissions within the SQL instance? I'm tasked with doing some cleanup and have found some cases where the database was deleted or moved to another server but the logins that used it were not deleted. I'd like to identify them to research.
For instance a query to show logins that have no permissions in any of the existing databases would be handy. I'm thinking it would be complicated by the need to loop through all of the existing databases and then outer join it to the list of instance level logins. Going to try to write something like that but was hoping that a script already exists.
I have multiple SQL 2008 severs with databases. Also, 1 mirroring server in place.

I want to Replace The Big Log database with A new one ( A database with same structure).But current DB has many connection .
This is my plan :
1- Create a new database with same structure.
2- Rename current database to olddb with this code :
USE master
GO
EXEC sp_dboption CurDataBase, 'Single User', True
EXEC sp_renamedb 'CurDataBase', 'OldDataBase'
GO
3- Rename Newdb to current DB.
USE master
GO
EXEC sp_renamedb 'NewDataBase', 'CurDataBase'
is it true ? and Tsql code is ok ? (dont forget many of connection to curdatabase (that Is a log db) and loss some seconds data is not problems)
