SQL Server Admin 2014 :: Point In Time Restores Referencing Copy-only Backups?
Nov 25, 2014
On one of our SQL Server 2014 boxes each database has a copy-only full backup made every night, in addition to the maintenance plan schedule of a full backup weekly, daily differential backups and log backups.
When performing a PIT restore in SSMS the restore file list lists the most recent copy-only backup as the full backup to use, not the most recent plan full backup. I noticed that using SSMS 2008 to start a PIT restore on the 2014 box does not have this problem, and lists the correct restore file sequence (ignores the copy-only backups).

Have a SQL 2014 install and cannot for the life of me get the maintenance plan to remove old backups. I've tried everything. Rights to the folder where the backups are stored are adequate, extension set in the clean up task is as it should be, etc. Log shows the job ran successfully. Running the command manually shows successful completion, but backups are still not removed.

Until yesterday I had a server running SQL Server 2008 R2 - with all the SQL Server DB files on an attached disk array.
The server died - so I attached the disk array to a new server - and all the DB data files are visible there.
I installed SQL Server 2014 on the new server and am trying to work out how to point it at the existing database files.
I also have backups of the DB's - but they will take ages to copy over and restore - so it would be much easier to just use the db files. Should I restore the master db first (easy as its small)?

Im backing up to a network directory thats actually a mount point on a different server.My backup was slower than usual so i opened up perfmon to have a look.
When selecting the mount point from the Logical Disks section in perfmon i can see that writes/sec & write bytes/sec both show zero for a long period of time, even though the backup percent complete is increasing.Then all of a sudden the writes to the network share jump massively.
Is there some caching mechanism for backups in sql where during a backup data is only flushed to the disk periodically during backup?

I am trying to create a job that would backup a DB dynamically to a different folder based on the week day. So if it's Saturday, backup to folder Saturday.
I have this
DECLARE @BackupLoc nvarchar (100)
DECLARE @DayOfWeek nvarchar (100)
set @BackupLoc = N'D:Backup'
set @DayOfWeek = (SELECT DATENAME(dw,GETDATE()))
set @BackupLoc = @backuploc + @DayOfWeek
[Code] ....
But it's giving me permission errors, although the AGENT and MSSQL service accounts are members of the local admins group.

My recommendation to my manager is to base recovery on .bak and .trn files. However the .mdf and .ldf files can be backed up without being detached and I am wondering about the value of these file backups. He has set up backups to external drive of the .mdf and .ldf but not of the .bak and .trn files that I have set up. His recovery strategy is based on complete backup of the machine and bare metal recovery. I am finding it hard to defend my preference for going about recovery with a new SQL Server installation, then restoring .bak files. Has tried recovery from .mdf and .ldf? Please note that all the database files (system and user) are on a single drive, I think this was set up to allow the machine to be clustered. We are intending to do a test rebuild of the machine from his backups.

This is my first deployment of an always on availability group for SQL 2014 and I'm trying to get my custom backup procedure to handle all databases appropriately depending on the primary group. Basiscally I want the system databases and all databases that don't participate in the availability group to be backed up on both nodes and those that do participate backed up ONLY on the primary server. I've looked at the sys.fn_hadr_backup_is_preferred_replica funcation, but would like to only have to test for a single databases existance in the availability group. If the one database is in the group, only backup the system databases and those that don't participate, otherwise backup everydatabase. This would be the case for both full backups and transaction logs.

We have a Customized share point application with Very minimal data usage and we have used only 5 to 6 lists and libraries only in the share point.
Configuration is
Clients -- fire wall --- Load Balancer ---- WF1 and WF2 --- SQL DB
ROUTING IS VIA FIRE WALL.
SUDDENLY THE SITE GOT DEAD SLOW AND UNABLE TO TRACE THE PROBLEM AS EVERY THING LOOKS FINE.
Checked with the firewall Team and they stated its fine from their end & even we have verified the counters, CPU, Memory & Page life expectancy, buffer counters all looks good and even we do not have huge data in the database. We have only 50 concurrent users are working...

What is the best approach for a read only copy of a database that is ~ 1TB. The primary database is fed nightly with an ETL process. We are currently trying to duplicate the ETL to read only server but that process is not going well. So we are looking at other options to let SQL make the copy.
The primary database is on a Win12R2 with SQL 12 or 14, a 2 node A/P failover cluster.
The read only copy will be on a Win12R2 with SQL 12 or 14. It is not a requirement to fail over to the read only copy if the primary should go down.
What would best the approach to accomplish the end result?

Hi,
I set up DB mirror between a primary (SQL1) and a mirror (SQL2); no witness. I have a problem when I issue command:
alter database DBmirrorTest
Set Partner = N'TCP://SQL2.mycom.com:5022';
go
The error message is:
The remote copy of database "DBmirrorTest" has not been rolled forward to a point in time that is encompassed in the local copy of the database log.
I have the steps below prior to the command. (Note that both servers' service accounts use the same domain account. The domain account I login to do db mirror setup is a member of the local admin group.)
1. backup database DBmirrorTest on SQL1
2. backup database log
3. copy db and log backup files to SQL2
4. restore db with norecovery
5. restore log with norecovery
6. create endpoints on both SQL1 and SQL2
CREATE ENDPOINT [Mirroring]
STATE=STARTED
AS TCP (LISTENER_PORT = 5022, LISTENER_IP = ALL)
FOR DATA_MIRRORING (ROLE = PARTNER)
7. enable mirror on mirror server SQL2
:connect SQL2
alter database DBmirrorTest
Set Partner = N'TCP://SQL1.mycom.com:5022';
go
8. Enable mirror on primary server SQL1
:connect SQL1
alter database DBmirrorTest
Set Partner = N'TCP://SQL2.mycom.com:5022';
go
This is where I got the error.
The remote copy of database "DBmirrorTest" has not been rolled forward to a point in time that is encompassed in the local copy
Thanks for any help,
KT

Copy mssqlsystemresource.mdf of a recently upgraded server and paste to an old server have same effect of upgrading via .exe installation?
My idea is to save time and administrative efforts in upgrades (Service Packs and/or Cumulative Updates) using this method.
According to BOL:
The Resource database makes upgrading to a new version of SQL Server an easier and faster procedure. In earlier versions of SQL Server, upgrading required dropping and creating system objects. Because the Resource database file contains all system objects, an upgrade is now accomplished simply by copying the single Resource database file to the local server.

In Windows Server 2012. How do I do a System Restore to a previous restore point?I need to install the 64 bit and 32 bit Oracle Client Install for connections in SSIS and to create Oracle Linked Servers.
If you make a mistake it is not fun removing it. Sometimes it corrupts the machine and it is difficult to uninstall since there is not an Oracle Universal installer for Oracle 11g.If you install the 32 bit before the 64 you mess up the machine.how to create a restore point.

Is there any way to backup a remote SQL Server that is on a hosted account to a local drive? We have a web hosted account that has a SQL Server that we do not have full admin rights on, just dbo access to the data and structure. We would like to be able to do backups and restores to our local development server if possible. Perhaps vis DTS or some similar means? WE cannot use the normal backup/restore as we do not have right to these fucntions nor can we access the servers local drives directly.

I proposed on a new server that we separate Data Files, Log Files, tempDB, Backups, etc. onto separate LUNS on a SAN with High Speed Solid State Drives.I was told that with the new technology with solid state SAN's that it would decrease performance and that it did not work the same way as it did when you had RAID 5's etc.I thought that if things were cared out correctly by a SAN Administrator they would know how to configure for optimal performance.

I've migrated a server with SQL Server 2008R2 and Reporting services into a new box with SQL Server 2014, but forgot to change the timezone to the correct one. I've changed it later, but it seems like the reports are running by the old default timezone. The schedule says that the report should run at 6:30am, but the Last Run column shows 8:30 PM.
I need to fix it without manually updating each subscription with some date/time conversion.

I've used some info on here to generate random dates within a given range and also random times - independently they work fine, but I can't seem to join them into a single field of datetime. I'm not sure why. The following snippet works fine as two independent fields:
select CAST(CAST(ABS(CHECKSUM(NEWID()))%(780)+(33968) AS DATETIME) as DATE) as theDate,
CAST(CAST(DATEADD(milliSECOND,ABS(CHECKSUM(NEWID()))%86400000 ,'00:00') AS TIME) as varchar(50)) as theTimeBut when I try to make it a single datetime field:
select CAST(cast(cast(CAST(ABS(CHECKSUM(NEWID()))%(780)+(33968) AS DATETIME) as date) as varchar(50)) + ' ' + cast(CAST(CAST(DATEADD(milliSECOND,ABS(CHECKSUM(NEWID()))%86400000 ,'00:00') AS TIME) as varchar(50)) as varchar(50)) as datetime)
Which returns with: Conversion failed when converting date and/or time from character string.
So what I am really looking for is a way to join those two values into a single datetime field... Or failing that that how to generate random dates within a range including random times...

This store procedure will get some executable queries from the select statement, the cursor will fetch each rows to execute the query and insert the queries into table_3 to mark as 'E'. Until 17:00, this store procedure will stop execute the queries and just get the queries from select statement insert into table_3 to mark as 'C'.
I don't know why the outputs in table_3 are quiet different than I think. This store procedure comes out with two exactly same queries and one marked as C and another marked as E.
CREATE PROCEDURE procedure1
AS
DECLARE cursor_1 CURSOR FOR
SELECT
'This is a executable query'

DECLARE @table_2

Hi all,
A few weeks back I had a problem with setting up Maintenance Plans on my SQL Server, the only fix in the end was re-install the SQL along with SP1. Since then backing up or restoring our developers database takes around 15-20 minutes whereas before it would take 1-2 minutes.
The server doesn't seem to be the problem as I have restored it to a 2nd server and get exactly the same problem there. Other databases on the same server of around the same size backup as expected.
The database is approximately 150MB's with the log file being 800MB's.
The server in question is a Dual Core Opteron 2.2Ghz with 4GB's of RAM, running Windows 2003 x64, fully patched and up to date. The SQL version is 2005 Standard Edition x64 also including SP1.
Plenty of disk space and no CPU activity even at the time of backups taking place.
Any help is much appreciated.

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.

I make two full backups on Oct 1 and Oct 10. I want to restore the server to a state in Oct 5. So I just do as follows:
1.Perform a transaction log backup on the server on Oct 23. I have never backup transaction log in the past.
2. Restore the server with Oct 1 full backup with NORECOVERY option.
3.Try to restore to the point at Oct 5 12:00, with the transaction log.
But the restore fails and SQL Server said the transaction log does not contain the point. The point is too early. Why? Also my .LDF file is about 13G, but the transaction log backup is only 200MB. Why?

Hello all,
First off, I appreciate the time that those of you reading and responding to this request are offering. My quesiton is a theoretical and hopefully simple one, and yet I have been unable to find an answer to it on other searches or sources.
Here's the situation. I am working with SQL Server 2005 on a Windows Server 2003 machine. I have a series of databases, all of which are in Full recovery mode, using a backup device for the full database backups and a separate device for the log backups. The full backups are run every four days during non-business hours. The log backups are run every half hour.
Last week, one of my coworkers found that some rarely-used data was unavailable, and wanted to restore a database to a point in time where the data was available. He told me that point in time was some time back in November.
To accomplish this, I restored the database (in a separate database, as to not overwrite my production database) using the Point in Time Recovery option. I selected November from the "To a point in time" window (I should note that this window is always grey, never white like most active windows, it seems), and the full database backup and the subsequent logs all became available in the "Select the backup sets to restore" window.
I then tried a bevy of different options from the "Options" screen. However, every restore succeeds (ie: it doesn't error out), but seems to be bringing the database back to a current point in time. It's never actually going back to the point in time I specify.
My questions are as follows:
a) Is it possible to do a point in time recovery to a point in time BEFORE the last full database backup?
b) If so, what options would you recommend I use? (ie: "Overwrite the existing database", restore with recovery, etc etc).
I again appreciate any and all advice I receive, and I look forward to hearing from anyone and everyone on this topic. Thank you.
Ryan

Is is true that in SQL Server 7, a point in time recovery can not read the active logs? So that any point in time recovery has to be with in some time frame of the backups of the logs?
Example:
If you have a full backup at 5 am.
Log backups every 2 hours.
You need to recover at 3:55. You would have to go back to your full backup from 2 am and the transaction logs from 6, 8, 10, 12, and 2.
You would lose any work done from 2-3:55pm?
