Backup - full recovery model

So where do I change it please ?
Is this the "BackupFull" option in the BackupBizTalkServer properties window ?

The Backup BizTalk Server SQL
Server Agent job is the only supported method to back up the BizTalk Server databases.
This job requires all BizTalk Server databases to use a Full Recovery Model.
How to maintain and troubleshoot BizTalk Server databases
Using

After connecting to the appropriate instance of the SQL Server Database Engine, in Object Explorer, click the server name to expand the server tree.
Expand Databases, and, depending on the database, either select a user database or expand System Databases and select a system database.
Right-click the database, and then click Properties, which opens the Database Properties dialog box.
In the Select a page pane, click Options.
The current recovery model is displayed in the Recovery model list box.
Optionally, to change the recovery model select a different model list. The choices are Full, Bulk-logged, or Simple.
Click OK.

DPM is Only Allowing Express Full Backups For a Database Set to Full Recovery Model

I have just transitioned my SQL backups from a server running SCDPM 2012 SP1 to a different server running 2012 R2. All backups are working as expected except for one. The database in question is supposed to be backuped up iwht a daily express
full and hourly incremental schedule. Although the database is set to full recovery model, the new DPM server says that recovery points will be created for that database based on the express full backup schedule. I checked the logs on the old DPM
server and the transaction log backups were working just fine up until I stopped protection the data source. The SQL server is 2008 R2 SP2. Other databases on the same server that are set to full recovery model are working just fine. If we
switch the recovery model of a database that isn't protected by DPM and then start the wizard to add it to the protection group it properly sees the difference when we flip the recovery model back and forth. We also tried switching the recovery model
on the failing database from full to simple and then back again, but to no avail. Both the SQL server and the DPM server have been rebooted. We have successfully set up transaction log backups in a SQL maintenance plan as a test, so we know the
database is really using the full recovery model.
Is there anything that someone knows about that can trigger a false positive for recovery model to backup type mismatches?

I was having this same problem and appear to have found a solution. I wanted hourly recovery points for all my SQL databases. I was getting hourly for some but not for others. The others were only getting a recovery point for the Full Express
backup. I noted that some of the databases were in simple recovery mode so I changed them to full recovery mode but that did not solve my problem. I was still not getting the hourly recovery points.
I found an article that seemed to indicate that SCDPM did not recognize any change in the recovery model once protection had started. My database was in simple recovery mode when I added it (auto) to protection so even though I changed it to full recovery
mode SCDPM continued to treat it as simple.
I tested this by 1) verify my db is set to full recovery, 2) back it up and restore it with a new name, 3) allow SCDPM to automatically add it to protection over night, 4) verify the next day I am getting hourly recovery points on the copy of the db.
It worked. The original db was still only getting express full recovery points and the copy was getting hourly. I suppose that if I don't want to restore a production db with an alternate name I will have to remove the db from protection, verify
that it is set to full, and then add it back to protection. I have not tested this yet.
This is the article I read:

Backup strategy for FULL recovery model

Hi,
We currently have a DB that is in a FULL recovery model and is Synchronized (mirrored) to a DR site. For extra safety, we are told to take regular backups of this db. Now is it possible to take a weekly FULL backup and then differential throughout
the week. OR have two FULL backups (Sunday and Wednesday) and then differential on other days.
Does the recovery model affect how a backup can be taken. Will this affect the log file (it is currently set to restricted growth by 400mb)
System: SQL Server - 2008 R2
Thanks.

Thanks Ashwin and Prashant. Based on your responses and the acceptable RTO i have the below backup plan.
Sunday and Wednesday FULL backup
Everyday - Differential
The transaction log done every hour.
For example:
Sunday 11:50pm - FULL backup done
Differential done daily at 1:00 am
So if the DB crashed or corrupted on Wednesday @ 6:am , I would have to restore with the below ?
-- Use the Sunday FULL backup
-- Use the differential from Wednesday @ 1:00 am
-- Use the transaction logs from 1:00 am to 6 am.
Would that work?

Changing from full recovery model to simple in sql 2012 always on

how do I change from a full recovery model to simple in an always on sql 2012 setup? When I try to change it it gave this error

The physical size of the log file will not change unless you manually shrink the file. A backup marks the log space as "reusable" internally.

What are Full Recovery models configured to content databases

hi
now in my SharePoint farm SharePoint Content Database are not configured to run with Full Recovery model
what are these full recovery models and is needed
adil

With a full recovery mode you can (in case of appropriate backuping) to restore database to almost any specific time. Like "Monday, 2:34PM".
So if your SharePoint site is using to exchange documents and heavily updating - I recommend you to switch Full mode on and backup full database at least once per week, backup logs every hour or as your information policy requires.
If this is mostly readonly site (like publishing portal) it is not a problem to run it in Simple mode, IMHO.

SQL Server Database - Transaction logs growing largely with Simple Recovery model

Hello,
There is SQL server database on client side in production environment with huge transaction logs.
Requirement :
1. Take database backup
2. Transaction log backup is not required. - so it is set to Simple recovery model.
I am aware that, Simple Recovery model also increases the transaction logs same as in Full Recovery model as given on below link.
http://realsqlguy.com/origins-no-simple-mode-doesnt-disable-the-transaction-log/
Last week, this transaction log became of 1TB size and blocked everything on the database server.
How to over come with this situation?
PS : There are huge bulk uploads to the database tables.
Current Configuration :
1. Simple Recovery model
2. Target Recovery time : 3 Sec
3. Recovery interval : 0
4. No SQL Agent job schedule to shrink database.
5. No other checkpoints created except automatic ones.
Can anyone please guide me to have correct configuration on SQL server for client's production environment?
Please let me know if any other details required from server.
Thank you,
Mittal.

@dave_gona,
Thank you for your response.
Can you please explain me this in more details --
What do you mean by one batch ?
1. Number of rows to be inserted at a time ?
2. or Size of data in one cell does matter here.
As in my case, I am clubbing together all the data in one xml (on c# side) and inserting it as one record. Data is large in size, but only 1 record is inserted.
Is it a good idea to shrink transaction log periodically, as it is not happening itself in simple recovery model.
HI Mittal,
Shrinking is bad activity yu should not shrink log files regularly, in rare case if you want to recovery space you may do it.
Have manual chekpoints in Bulk insert operation.
I cannot tell upfront what should be batch size but you can start with 1/4 th of what you are currently inserting.
Most important what does below query return for database
select log_reuse_wait_desc from sys.databases where name='db_name'
The value it returns is what stopping the log from getting cleared and reused.
What is version and editon of SQl server we are talking about. What is output of
select @@version

Why db mirror can not set db recovery model to simple?

Hi ,All
I have a question .
DB replication can set db recovery model to simple ,why db mirror can not db recovery model to simple.
DB mirror must be set to full recovery model.
As far as I know, whatever db mirror and db replication ,there is a log reader to read the log in the ldf file
DB mirror and DB replication are almost the same principle to replicate the db to another db server
Thanks a lots
Love SQL

Database mirroring involves redoing every
insert, update, and delete operation that occurs on the principal database onto the mirror database as quickly as possible. Redoing is accomplished by sending a stream of active transaction log records to the mirror server, which applies log records to the
mirror database, in sequence, as quickly as possible. Unlike replication, which works at the logical level, database mirroring works at the level of the physical log record.
There is no log reader agent in case of mirroring its more internal. Mirroring
uses the transaction log to redo everything at the mirror site. In simple recovery model, the transaction log is effectively transitory and only enough information is kept in the log for undo/redo to keep the database consistent during
crash recovery. Thats why mirroring does not work in simple recovery model.

DIFFERENCE BETWEEN THE FULL AND BULK-LOGGED RECOVERY MODEL

DIFFERENCE BETWEEN THE FULL AND BULK-LOGGED RECOVERY MODEL

In bulk logged recovery mode certain bulk operations are minimally logged. In FULL recovery mode these are fully logged. These bulk operations are as mentioned below
1. SELECT INTO
2. BULK IMport operations including BULK INSERT and BCP
3. INSERT INTO SELECT command using the OPENROWSET(BULK) function
4. Partial updates to columns having large value data type
5. Using WRITE clause in UPDATE statements
6. Index operations e.g CREATE INDEX, ALTER INDEX REBUILD , DROP INDEX
In Bulk Logged Recovery Mode when you execute these operations SQL Server only logs the fact that these operation occured and information about space allocation. The actual change in the data is maintained in the BCM (Bulk
Changed Map)
Since the actual changes are not recorded in the log file, the log file size in the reletively less in size but this tradeoff comes with the price of increased backup time. This is so because during the log backup its not just the log being backup, but also
the extents that are marked by the Bulk Changed Map as changed.

Restore a log backup on to database whose recovery model is SIMPLE ?

Hi All,
Today, it was new thing I found when I was testing some log shipping?
Question is can we restore a LOG BACKUP on a database whose recovery model is SIMPLE?
Brief background:
I setup log shipping in SQL Server 2012 SP1 Enterprise Edition between 2 instances. Log shipping is in Standby/readonly mode. So, everything was working very fine...
Now I changed the recovery model of secondary database on 2nd instance from Full to SIMPLE, still the restores are happening very fine. So, is this a normal behavior? other thing is once after restore job is complete the recovery model is getting changed to
FULL automatically on secondary db and I verify it before and after restore job using below query:
select name,recovery_model_desc from sys.databases
Based on my knowledge when a database is in SIMPLE recovery model, we can't perform any log backups on the database and since no log backups, we cant perform Point in Time recovery?
Please clarify what I am seeing is normal ? Also, would like to know what is happening behind the scenes?
Thanks and appreciate your help.
Sam

Hi,
>>Question is can we restore a LOG BACKUP on a database whose recovery model is SIMPLE?
Yes you can restore Log backup on database which is in simple recovery.
You must understand what recovery model is for. Recovery model affects Logging and recovery of a database it does not puts restriction on what can be restore on it. Of course you cannot take log backup of database in simple recovery but you can restore.
Reason being in simple recovery log is truncated after checkpoint (unless something is holding logs like long running transaction). Recovery model also controls the extent of logging which would be done for transaction and hence recovery which you can do

Time Machine Full Recovery From Wireless Backup

I am reporting this as a learning experience for all.
I just had a hard drive fail on my MacBook. Apple Care was golden and now I have a clean install with Leopard.
Here is my situation. MacBook backed up via time machine on a wireless network. Windows on boot camp partition. Dedicated disk (1TB Buffalo) connected to wife's iMac via firewire.
I want to do a full recovery. I start up leopard and it gives me the option to do a full recovery during setup. I have no time machine backup list provided. I continue with setup. When I go to the recover option of time machine I am asked to select a file. This is when I call tech support.
Tech Support says I should have had the backup disk connected directly via firewire for setup to see it. Time machine stores the backup under these conditions as a Sparse bundle. Now that I am past setup I have to do a migration rather than a recovery. I start up the migration assistant and I still cannot access the sparse bundle as it is grayed out. The leap here is you have to mount the sparse bundle, double click, then it shows up as a disk you can migrate from.
Windows Partition, as TS puts it is "on its own".
The confusion for me was that I could not recover exactly as I had backed up.
I hope this helps someone. Cheers!

It seems to be. All music, photos, applications, etc. are present. I have not had time to do a complete review of my migration, I will track this post for a while and report any problems. There were significant OS updates which were required. I thought that they would be included as part of the migrate, not so. Perhaps they are on a true "full recovery" from setup, any one know?
Migration has no option for any part of the OS. It assumes you already have it.
If you recover your entire system from a TM backup (assuming nothing significant was excluded), you get your entire system back exactly the way it was: the OS, Apps, settings, preferences, user data, etc.
You don't load a new OS from the Leopard Install disc -- you only use it for it's copy of Disk Utility and the installer -- everything else comes from your TM backup.

Is it risk the data lost switch from Full Recovery mode to Simple Mode?

Please click the Mark as Answer button if a post solves your problem!

Also.. When you change recovery model of the database, first thing you do is the full database backup.
This is assure you that you do not loose data because of change in recovery model.
Please mark this reply as answer if it solved your issue or vote as helpful if it helped so that other forum members can benefit from it
Almost right, without question you need to take a backup if you are changing from Simple to Full; switching between full and bulk logged and vice versa does not affect your point in time recovery options; backing up after switching to Simple is not necessarily
essential but it is advisable.

SQL Server transaction log not truncating in simple recovery model mode

The transaction log for our SQL Server database is no longer truncating when it gets to the restricted file growth limit set by the autogrowth settings. Previously - as expected - it would reach this limit and then truncate allowing further entries. Now
it stays full and the application using it shuts down. We are using 2008 R2 and the recovery model is set to simple. Is this a known behaviour / fault which can be resolved ? Thanks.

As already suggested check wait type in log_reuse_wait_desc from sys.databases and open transaction on the database.
Also, check long running SPIDs are waiting for from sys.sysprocesses from wait_type column
0 = Nothing - What it sounds like.. Shouldn't be waiting
1 = Checkpoint - Waiting for a checkpoint to occur. This should happen and you should be fine - but there are some cases to look for here for later answers or edits.
2 = Log backup - You are waiting for a log backup to occur. Either you have them scheduled and it will happen soon, or you have the first problem described here and you now know how to fix it
3 = Active backup or restore - A backup or restore operation is running on the database
4 = Active transaction - * There is an active transaction that needs to complete (either way -
ROLLBACK or COMMIT) before the log can be backed up. This is the second reason described in this answer.
5 = Database mirroring Either a mirror is getting behind or under some latency in a high performance mirroring situation or mirroring is paused for some reason
6 = Replication - There can be issues with replication that would cause this - like a log reader agent not running, a database thinking it is marked for replication that no longer is and various other reasons. You can also see this reason and it is
perfectly normal because you are looking at just the right time, just as transactions are being consumed by the log reader
7 = Database snapshot creation You are creating a database snapshot, you'll see this if you look at just the right moment as a snapshot is being created
8 = Log Scan I have yet to encounter an issue with this running along forever. If you look long enough and frequently enough you can see this happen, but it shouldn't be a cause of excessive transaction log growth, that I've seen.
9 = An AlwaysOn Availability Groups secondary replica is applying transaction log records of this database to a corresponding secondary database

If your database in Full Recovery mode, can you use Bulk Insert Task to load data

If your database in Full Recovery mode, can you use Bulk Insert Task to load data

If your database in Full Recovery mode, can you use Bulk Insert Task to load data
Yes you can ofourse but dont be in idea that logging will be mininal. Loggign will be as per recovery model full. Every thing will be logged. If you are going to use bulk insert task you can consider switching recovery model to Bulk logged but you will not
have option to do point in time recovery.
PS: please dont create duplicate threads
If you read first Note section in below link it clearly states that yes logging will be full and you can use

Rman backup full then level 0 and level 1 Weekly

Please share your thoughts of backups.
Friday -> Take a full rman backup
Saturday -> Take a level 0 rman backup -> If recovery needed restore full and apply level 0 ?
Sunday -> Take a level 1 rman backup -> If recovery needed restore full and apply incremental 1 ?
Monday -> Take a level 2 rman backup -> If recover needed restore full and apply incremental 1 ?
Tuesday -> Take a level 1 rman backup -> If recover needed restore full and apply incremental 2 ?
Wednesday -> Take a level 2 rman backup -> If recovery needed restore full and apply incremental 1 ?
Thursday -> Take a level 1 rman backup -> If recovery need restore full and apply incremental 2 ?
Thanks

Please note that Full and level 0 backs are same...
Sunday -> Take a level 0 rman backup
Monday -> Take a level 1 rman backup
Tuesday -> Take a level 1 rman backup
Wednesday -> Take a level 2 rman backup
Thursday -> Take a level 1 rman backup
Friday-> Take a level 1 rman backup
Saturday -> Take a level 1 rman backup
Taking level 2 in the middle of the week, so that in case of any recovery you need ao apply changes since the last level 0, 1 or 2

Is backup full database , is backuing up controlfile ?

Hi
i am on 8174
is that enough to cold backup the database?
shutdown immediate;
startup mount;
run {
allocate channel t1 type 'SBT_TAPE';
send 'NB_ORA_POLICY=....';
backup full format 'bk_%U_%t' (database);
or do i need
backup current controlfile; ?
i can see here http://download-west.oracle.com/docs/cd/A87860_01/doc/server.817/a76990/rmanconc.htm#436070
this statment "A full backup is different from a whole database backup, which is a backup of all datafiles and the current control file."
is that means
backup full database , is backuing up controlfile ?(i think yes) and is restoring from it requires any archivelogs?(i think no)
Thanks very much
Edited by: user9145417 on 25-Aug-2010 16:42

The reason to have the current controlfile is that it keeps all the information of the database. If you lose the entire machine, it will be much more difficult to recover to another machine without that controlfile. That is one reason that control files are multiplexed, so that you do not lose all of them.
With 8174 I don't believe there was a method to always included it automatically like with 10g. So yes...always backup your control file with an exact statement.
Will you need archive logs? If you want to do a complete recovery you will need all the archivelogs that occur after the start of the backup untill the time the database crashes.
Do you need to backup the archivelogs within this script? Well that depends if you can think of any circumstance that would require you to recover to a point in time using the backup taken before this one.

Tim
