Basic questation about sql backup

HI all, sorry for my englisch . I have quetstaion about DPM and SQL 2012 database recovery model .
If I select recovery model simple , that DPM always backup full backup ... This create with vss providera ?
If I select full backup what work synchranization ? Every log files is copy to replica , and after copy truncate log ?
thanx
Falcon

For application data that support incremental backups (exchange, SQL Db's in full recovery mode) there are two job types.
A) Synchronization - This is equivalent of an incremental backup and only brings over log changes. Each incremental synchronization is equivalent to a recovery point. Each incremental synchronization results in application log truncation which
is performed by the application (SQL / Exchange)
B) Express full - This is equivalent to FULL backup, however only brings over Database changed blocks and applies them to the replica volume then makes a snapshot Each express full backup is recoverable. Express full backups do not result
in log truncation by the application. There is a 512 snapshot limit for express full backups.
For applications that do not support incremental backups (SharePoint, SQL Db's in simple recovery mode, Hyper-V VMs) always use express full backups.

Basic questation about backup SQL database

Hi I have basic questation about backup database . If I set DPM to backup database and the database have full model and another application truncate log. Detect this dpm and create full backup or create error ?
Falcon

Hi,
If you want another backup process to truncate the logs instead of DPM, you can just configure DPM to synchronize
just before a recovery point. That basically tells DPM to just perform express full backups which will not truncate logs.

Basic questation about VSS and windows backup

hi all, basic questation about backup and VSS
Environment:
windows 2008r2,NAS backup disk connected with iSCSI
If i create in the windows backup server job , where i backup disk D , target is NAS disk and start it . Windows backup is requester and is created shadow copy . This shadow copy is created in the disk D or in the NAS disk ? If in the disk D is created for
everyone application snapshot ? After created snapshot the windows backup copy data from snapshot to windowsimagebackup ? And If windows backup create different snapshot how detect which files is changed ?
thank you
Falcon

Hi,
Windows Server Backup stores backup versions in volume shadow copies. After the data write is complete, Windows Server Backup creates a shadow copy of the volume where the backup is stored using Volume Shadow Copy Service (VSS). This shadow copy retains the
state of the storage volume as a “backup version” or “point-in-time” of the backup and must restore using this backup version.
You could refer to the article below to know the steps of a back up operation performs:
Backup Version and Space Management in Windows Server Backup
http://blogs.technet.com/b/filecab/archive/2009/06/22/backup-version-and-space-management-in-windows-server-backup.aspx
Windows Server Backup uses Volume Shadow Copy Service (VSS) and block-level backup technology to back up and recover your operating system, files and folders, and volumes. The Volume Shadow Copy Service is used to differentiate between backup sets, and to track
where the various blocks are being written to within the shadow copy storage.

Basic questation about MBAM

HI all , sorry for basic questation .
I try set with gpo mbam client in the windows 7 . I set requerid encrypt os drive and fixed drivers .and questtaion :
in the error log is write :
detect OS volume encryption policies conflict . check bitlocker anb MBAM policies related OS drive protectors .
I set MBAM only in MBAM GPO .
an second quetstaion .
I cannot enable bitlocker only with GPO ? I must enable manualy ?
thanx
Falcon

Recovery key and the PIN are two different protectors. PIN is something you set to unlock your machine at boot. It provides an additional protection. You can always change the PIN choosing option, bitlocker drive encryption option from control panel.
Recovery key is to log in the machine if your machine goes into the recovery mode. If you will not be able to access your OS Drive how you will be able to boot. TPM string is called as the Ownership Hash password which is different from the recovery string
of the OS Drive which is a 48 digit numerical password.

Some basic questation about mbam and bitlocker

Sorry for questation . What doing options Auto-unlock ?
allow auto-unlock and require auto-unlock .
and exist some construction betwen setting fixed drive and os drive . If I disable encrypting fixed drive or set only read fixed drive it mean that os drive is set to ?

Basic questation about how works DPM

HI all,
sorry how DPM detect which files is changed I must copy to replika ? Or how is created replika . DPM also reguester create full backup and then use incremental backup copy-and-write method ?
thanx
Falcon

Closing for housekeeping.
DPM uses a file system filter driver (DPMFilter) to track block level changes between backup times and only transmits changed file blocks during synhronizations for file data. DPM never transfers the whole file except for initial replica
creation.

Basic questions about config backup/restore

I've searched around with limited success. I've just inherited the Ironport devices in our enviornment and need to perform an OS upgrade of our cluster. Prior to doing so, I want to backup each members config file. (also, I want to do this before doing any config changes)
If I back up each member's config to the device, how I can access/edit these config files so I can replaced the masked password fields with the actual passwords?
I'm aware of the unmasked/hashed password version of the file, but we'd like to avoid that if we can.

The config file itself is just a text/xml file and most good text editors (vi/textpad) will handle it easily.
Even when passwords are not masked, they are always encrypted. The only way to manually insert a password would be to encrypt it and put the result back in the config file.
As long as you are choosing strong passwords (hint) it is not at all an easy task to force decrypt the hashed password string. Even if you are completely paranoid, just store the config file somewhere in an encrypted format.
Bottom line: don't mess up your "backup" by manipulating it in a way that could render it useless just when you most need it. Manual editing of config files is tricky and AFAIK not officially supported in any way.

Basic questation

HI ,
I have 2 basic questation about adobe premiere element 7 . Can I intergarte 2 clips to one clips ? And can I cahnge speed of the clip with the keyframe ? I wan in the begin clip slow and accelerate .....
thanx

Marek,
To elaborate on what Steve says in Post 10, what you have on your Timeline is a pair "virtual" Clips. They appear as separate on the Timeline only, but Premiere is referencing back to your original Clip, which is in your Project Panel. It has not been physically cut, but has just had references added to it for editing.
When you Delete the second Clip, the one you "created," and drag the end of the first Clip back out, you are just erasing those references. Your Clip is essentially now unchanged.
The Undo (Ctrl-z) works while you are editing. If you Save your Project and close it, you cannot use the Undo. You can also use your History Palette (Window>History) to have multiple Undo's. These also disappear when you Save and Close, then reopen PE.

DPM failing SQL backups due to error: "the SQL Server instance refused a connection to the protection agent. (ID 30172 Details: Internal error code: 0x80990F85)

I ran across this error starting on 6/4/2011 and have been unable to find the root of the problem. In our environment, we have a DPM 2010 server dedicated to backing up all our SQL envrionment (about 45 SQL Servers total). All of the SQL
environment is backing up fine except for a SQL Cluster Application. This particular SQL Instances is part of a 6 node failover cluster with 6 SQL Instances distributed amongst them. The other 5 SQL instances in the cluster are backing
up fine; only one instance is failing. The DPM Alerts section shows this error when attempting to do a SQL backup of one of the databases on this SQL instance:

I have checked the cluster node this particular SQL instance is running on using Perfmon and the machine is nowhere near capacity on CPU, memory, network, or Disk I/O.  I have failed this SQL Application to another node in the cluster and
receive the same error (this other node has another clustered SQL application on it that is actively running as well as backing up fine). The only thing that I am aware of that has changed is that we installed SP2 for SQL 2008 about 2 weeks prior
to when the failures started to occur. However, we updated all six clustered SQL Instances at the same time and only this one is having this issue so I don't believe that caused the problem. We are running SQL 2008 SP2 (version 10.0.4000.0)
on all clustered instances along with DPM 2010 (version 3.0.7696.0) on this particular DPM server that has the issue.
One last thing, I have also noticed errors in the event log pertaining to the same SQL backups that are failing (but the time stamps are not concurrent with each backup attempt):

Any help would be greatly appreciated!

Don't know if this helps or not, but I also noticed another peculiar issue that is derived from this problem. If I go to "Modify protection group", then expand the cluster, then expand all six nodes in the cluster, five of them show "All SQL Servers"
and allow me to expand the SQL Instance and show all databases; the one that is having a problem backing up, when I expand the node, doesn't even show that SQL exists on the node, when in fact, it does.
I would also like to add that the databases on this node that will not backup are running fine. They run hundreds of transactions daily so we know SQL itself is OK. Even though it is a busy SQL Server, there is plenty of available resources as
the SQL buffer and memory counters show the node is not under durress.

Basic Questions about Package Installation

I have one basic question about installing packages.
How can I find out if needed software is already installed without knowing the name of the package?
For e.g. I want to know, if the MYSQL Server is already installed but I don't know the Package name.
How can I find out the package name of needed software?

Difficult.
Assuming the string "MYSQL" appears somewhere in the package
name or the package description, you can grep the output from
"pkginfo". That is "pkginfo | grep -i sql" would list all installed
packages that contain the substring "sql" with either upper- or
lowercase letters.

Questation about instaling MBAM 2.5

b)if I try install Administration website the installer want ASP.NET MVC runtime . In the microsoft pages I found link and try install . but in the firts step is download and install express database why ???
thank you for answer

Basic question about importing wma files

Hi, I have a basic question about importing wma files. I ripped some cd's on a Mindows computer using Media Player, but now want to copy them to my Mac and use them in iTunes on my Mac. when I use Import in iTunes, nothing happens and I cant even seem to copy them one by one using the Music folder.
Can someone help me?
thanks
eMac Mac OS X (10.4.4)

iTunes for Mac doesn't support .wma files.
If you can use a PC to convert them, you can use one of many freeware applications. Google for 'wma to mp3'.
For the Mac there's the shareware program EasyWMA that can convert them.
Hope this helps.

Here's a very basic question about 2 TB external drives and Time Machine.

Here's a very basic question about 2 TB external drives and Time Machine.
Ihave a Mac Pro with a .75 TB and 1 TB drive. It also has a 1 TB 2ndinternal drive. My current external drive is too small so I'll begetting a 1.5 TB or 2 TB drive.
Obviouslythe new larger 2 TB drive will backup everything on the Mac Prointernal drive with Time Machine. But there will be 1 TB of space leftover going to waste.
ShouldI partition the external drive so that the TM portion will be 1 TB andthe use the remaining extra partition for additional file backups withCarbon Copy?
Thanks for any insights.
I tried searching around on the new Apple discussion forum, but I find it much harder to use than the old forum I used to use.

The problem with terabyte drives is that that a 3 TB is about as big as you can get without going into RAID territory. Ideally, a Time Machine drive should be 3 times as large as all the drives you are backing up. So, if you have 2.75 TB of internal storage, you should have 8 TB of Time Machine space.
Of course, that is "should". If your TB drives are mostly empty, then you can get away with something 3 times the size of your used disk space. Just remember that you are pushing it. Linc is right about Time Machine needing space to work.
It is unlikely that you have regular churn on 2.75 TB of disk. I suggest identifying which drives and folders have the most activity and excluding those drives and directories that don't change much. It would be better to archive the data that doesn't change often and keep it out of Time Machine. Then you may be able to get away with a 2 TB Time Machine drive.

Advice on SQL Backup POC tests

Hello,
We are going to be performing a POC for backup software. I don't know much about restoring SQL2008 and SQL2010 so I would like to know what tests SQL pros would want to see succeed before approving a solution. One of our DBAs will be participating later in
the process.
Thanks,
Robert

Robert,
Just as an FYI - there is no such thing as "SQL2010".
Most backup software uses an agent and runs through VSS which is great if you want to backup windows, but isn't so great when it comes to SQL Server.
Things to watch out for:
1. The need of point in time recovery: While VSS does support this for SQL Server, it will not truncate the logs which means some other process will need to be run if the database is in full or bulk logged recovery model.
2. Use of Log shipping in the environment: Since part of log shipping is to take log backups and "ship" them to other servers, your essentially making this null and void. This is because SQL Server takes the log backups (which your software will now take
over doing) and puts them somewhere (configurable). Since the software will be taking over, it'll either need to have the ability to do the file movement needed for log shipping or you'll pretty much have to abandon the use of it. Also, see point #1 as log
shipping require the full or bulk_logged recovery model.
3. The use of Availability Groups in the environment: Akin to #2, backups can be taken on databases in an availability group. VSS does not take this into account as it doesn't need to. This is a SQL Server level item, not an OS level item. You'll somehow
need to build logic into the agent to first check and see if the database is part of an availability group, then check to see where the preferred backup place is, then if both are good take the backup. It also won't truncate the log as per #1 since availability
groups need the full recover model. (See a pattern?)
4. Differential: AFAIK since this is at a SQL Server level, it's not possible with VSS or agents unless the agent issues T-SQL Backup commands... at which point why run an agent or buy backup software?
5. File, Filegroup, ReadOnly filegroups, etc: See #4 for the same reason.
So that's just a few things to think about for backups, now for restores:
1. Does the software support restoring to other servers with dissimilar drive layouts?
2. Does the software support leaving databases to a point in time recovery not at a restore point? For example, at 2:53:02.666 AM or at a marked transaction (if those are used)?
3. Does the software support truncating logs after a log backup is complete?
4. Does the software support native backups with copy_only to not break log chains when needing to send to a vendor or otherwise take an out of band backup?
5. Does the software support piecemeal or partial restores (if enterprise edition and backup strategy supports it) for larger or more important databases?
Now for some admin (non-technical) items...
1. Who will be in charge of backups?
2. Who will be in charge of restores?
3. Who and how will people get/be notified if a backup fails?
4. Will your SLAs be blown if VSS has an issue (which generally required a reboot to fix) and database can't be backed up?
5. Is it possible to get a native backup out of the system if another team, project, or company needs it?
It might seem simple at first, I mean it's just a backup right... but there is definitely more going on depending on needs. If you're the kind of company that does simple recovery model for everything and plain vanilla the rest of the way - you might not
have any issues and pretty much anything will work for you. If you're the kind of company that runs different configurations, have dev environments that need refreshed daily or weekly, use any advanced features of current t-sql based backups, etc, you'll probably
end up not using the agent for the backup software and just sweeping disk or something of the like.
Good luck.
