Sql backup best practice on vms that are backed up as a complete vm

hi,
apologies as i am sure this has been asked many times before but i cant really find an answer to my question. so my situation is this. I have two types of backups; agent based and snap based backups.
For the vm's that are being backed up by snapshots the process is: vmware does the snap, then the san takes a snap of the storage and then the backup is taken from the san. we then have full vm backups.
For the agent based backups, these are only backing up file level stuff. so we use this for our sql cluster and some other servers. these are not snaps/full vm backups, but simply backups of databases and files etc.
this works well, but there are a couple of servers that need to be in the full vm snap category and therefore cant have the backup agent installed on that vm as it is already being backed up by the snap technology. so what would be the best practice on these
snapped vms that have sql installed as well? should i configure a reoccurring backup in sql management studio (if this is possible??) which is done before the vm snap backup? or is there another way i should be backing up the dbs?
any suggestions would be very welcome.
thanks
aaron

Hello Aaron,
If I understand correctly, you perform a snapshot backup of the complete VM.
In that case you also need to create a SQL Server backup schedule to perform Full and Transaction Log backups.
(if you do a filelevel backup of the .mdf and .ldf files with an agent you also need to do this)
I would run a database backup before the VM snapshot (to a SAN location if possible), then perform the Snapshot backup.
You should set up the transaction log backups depending on business recovery needs.
For instance: if your company accepts a maximum of 30 minutes data loss make sure to perform a transaction log backup every 30 minutes.
In case of emergency you could revert to the VM Snapshot, restore the full database backup and restore transaction log backups till the point in time you need.

Portal backup best practice!!

Hi ,
Can anyone let me know where can i get Portal Backup Best Practices!! We are using SAP EP7.
Thanks,
Raghavendra Pothula

Hi Tim: Here's my basic approach for this -- I create either a portal dynamic page or a stored procedure that renders an HTML parameter form. You can connect to the database and render what ever sort of drop downs, check boxes, etc you desire. To tie everything together, just make sure when you create the form, the names of the fields match that of the page parameters created on the page. This way, when the form posts to the same page, it appends the values for the page parameters to the URL.
By coding the entire form yourself, you avoid the inherent limitations of the simple parameter form. You can also use advanced JavaScript to dynamically update the drop downs based on the values selected or can cause the form to be submitted and update the other drop downs from the database if desired.
Unfortunately, it is beyond the scope of this forum to give you full technical details, but that is the approach I have used on a number of portal sites. Hope it helps!

Unity Backup Best Practices

We are looking at our Disaster Recovery when it comes to our Unity Voicemail servers and I am looking for some Best Practices when it comes to backing up Unity. Does anyone have any whitepapers/suggestions? Thanks.

if you mean unity backup as in backing up the data, then the suggested method is four fold...
1) using a backupExec or the likes, with a SQL agent, backup the SQL database(s) on unity.
2) using a backupExec or the likes, with an Exchange agent, backup the Exchange database(s) used by unity.
3) using a backupExec or the likes, perform a Windows 2000/2003 full backup including SystemState. (open file option is also available for backupExec)
4) for DR recovery purposes, using DiRT, backup the unity system.
see this link for more unity backup info:
http://www.cisco.com/en/US/products/sw/voicesw/ps2237/products_white_paper09186a00801f4ba7.shtml
if you mean backing up unity as far as failover, then you can use the link that follows to create a failover environment for your unity:

SQL server Best Practice Analyzer output in .CSV

Hi Team, I ran SQL server Best practice analyzer on our SQL 2008 R2 server. I was trying to export scan result in .csv format but it is only giving me option to save it in .xml format. I have been looking for ways to export output in such a way
that it can be readable and I can send it to our clients but no luck.
How can I export SQL BPA output in .csv or any other user friendly format?
Thanks in Advance.

Hi MSRS27,
You can run Best Practices Analyzer (BPA) scans either from Server Manager, by using the BPA GUI, or by using cmdlets in Windows PowerShell. We can view or save BPA results from Windows PowerShell session in different format.
If you want to export BPA results to a comma-separated values (CSV) text file, run the following cmdlet, where Path represents the path and text file name to which you want to save the CSV results.
CSV results can be imported into Microsoft® Excel, or other programs that display data in spreadsheets or grids.

HT4859 how do you see the items that are backed up to iCloud - I have 4.5 GB that I have used but I cant find where to see those items...help

how do you see the items that are backed up to iCloud - I have 4.5 GB that I have used but I cant find where to see those items...help

That is everything in your iCloud account. Videos and camera roll photos are only included in your backup, the size and content of which you can see on your phone in Settings>iCloud>Storage & Backup>Manage Storage>tap the name of your device under Backup. This will show you the size of "Camera Roll", where these are contained. (You can't see any detail beyond that.) Photo stream photos can only been seen in your photo stream album on your phone, and they don't count against your storage so they aren't part of the 4.5 GB. Everything esle is either in the backup, the items listed in Settings>iCloud>Storage & Backup>Manage Storage, or on icloud.com, where you can see your contacts, calendars, etc.

My phone was stolen. I first backe up from the icloud but then synced with my computer and lost some pictures that are backed up on the cloud. How do I get pics from my old phone which are backed up on the cloud but are not in my photostream?

If you have an iCloud backup, restore it to your phone as explained here: https://support.apple.com/kb/ph12521. If you have a backup on your computer instead, restore it to your phone by connecting your phone to your computer, opening iTunes and going to File>Devices>Restore from Backup.

If you delete your icloud backup will it delete everything that was backed up?

If you delete your icloud backup will it delete everything that was backed up?

It will only delete the backup from iCloud. It won't delete anything from your phone.

HT201269 I am not finding my backup of my Iphone 5 that I backed up in itunes. I need to put the old information on my replaced phone from Apple care.

I am not finding my backup of my Iphone 5 that I backed up in itunes. I need to put the old information on my replaced phone from Apple care.

the itunes back up can be found in preferences/devices on ur itunes
the preferences can be reached by going to:
windows pc: edit/preferences
mac pc: itunes/preferences
check ur icloud as well in case u had the 'back up to icloud' option checked instead of the 'to this computer' option when u backed it up to ur itunes.
if neither of those have ur back up then ur back up is not in that pc and not in ur icloud for that apple id. it might be somewhere else (another pc maybe) or it doesnt actually exist.

I have lost my iPhone 5. How can I get photos that are backed up on iCloud?

Hello,
I have lost my iPhone 5. How can I get photos that are backed up on iCloud?
Thanks!

I wish, essentially you have an image file of your personal information integrated with parts of IOS in the cloud server. If you had it on your computer - you could use one of the software extractors (bunch with google search, paid and free). From icloud server it can be restored to other iphone, ipod touch, ipad - then backed up or imported to computer for you. Then that other device can return to your friend or family member. That is the only way I can think of.

OVM Repository and VM Guest Backups - Best Practice?

Hey all,
Does anybody out there have any tips/best practices on backing up the OVM Repository as well ( of course ) the VM's? We are using NFS exclusively and have the ability to take snapshots at the storage level.
Some of the main points we'd like to do ( without using a backup agent within each VM ):
backup/recovery of the entire VM Guest
single file restore of a file within a VM Guest
backup/recovery of the entire repository.
The single file restore is probably the most difficult/manual. The rest can be done manually from the .snapshot directories, but when we're talking about having hundreds and hundreds of guests within OVM...this isn't overly appealing to me.
OVM has this lovely manner of naming it's underlying VM directories off of some abiguous number which has nothing to do with the name of the VM ( I've been told this is changing in an upcoming release ).
Brent

Please find below the response from the Oracle support on that.
In short :
- First, "manual" copies of files into the repository is not recommend nor supported.
- Second we have to go back and forth through templates and http (or ftp) server.
Note that when creating a template or creating a new VM from a template, we're tlaking about full copies. No "fast-clone" (snapshots) are involved.
This is ridiculous.
How to Back up a VM:1) Create a template from the OVM Manager console
Note: Creating a template requires the VM to be stopped (this is required because the if the copy of the virtual disk is done with the running will corrupt data) and the process to create the template make changes to the vm.cfg
2) Enable Storage Repository Back Ups using the step above:
http://docs.oracle.com/cd/E27300_01/E27309/html/vmusg-storage-repo-config.html#vmusg-repo-backup
2) Mount the NFS export created above on another server
3) Them create a compress file (tgz) using the the relevant files (cfg + img) from the Repository NFS mount:
Here is an example of the template:
$ tar tf OVM_EL5U2_X86_64_PVHVM_4GB.tgz
OVM_EL5U2_X86_64_PVHVM_4GB/
OVM_EL5U2_X86_64_PVHVM_4GB/vm.cfg
OVM_EL5U2_X86_64_PVHVM_4GB/System.img
OVM_EL5U2_X86_64_PVHVM_4GB/README
How to restore up a VM:1) Then upload the compress file (tgz) to an HTTP, HTTPS or FTP. server
2) Import to the OVM manager using the following instructions:
http://docs.oracle.com/cd/E27300_01/E27309/html/vmusg-repo.html#vmusg-repo-template-import
3) Clone the Virtual machine from the template imported above using the following instructions:

SAP Business One 2007 - SQL Security best practice

I have a client with a large user base running SAP Business One 2007.
We are concerned over the use of the sql sa user and the ability to change the password of this ID from the logon of SAP Business One.
We therefore want to move to use Windows Authentication (ie Trusted Connection) from the SAP BO logon. It appears however that this can only work by granting the window IDs (of the SAP users) sysadmin access in SQL.
Does anyone have a better method of securing SAP Business One or is there a recommended best practice. Any help would be appreciated.
Damian

See Administrators Guide for best practise.
U can use SQL Authentication mode Don't tick Remember password.

Development System Backup - Best Practice / Policy for offsite backups

Hi, I have not found any recommendations from SAP on best practices/recommendations on backing up Development systems offsite and so would appreciate some input on what policies other companies have for backing up Development systems. We continuously make enhancements to our SAP systems and perform daily backups; however, we do not send any Development system backups offsite which I feel is a risk (losing development work, losing transport & change logs...).
Does anyone know whether SAP have any recommendations on backuping up Development systems offsite? What policies does your company have?
Thanks,
Thomas

Thomas,
Your question does not mention consideration of both sides of the equation - you have mentioned the risk only. What about the incremental cost of frequent backups stored offsite? Shouldn't the question be how the 'frequent backup' cost matches up with the risk cost?
I have never worked on an SAP system where the developers had so much unique work in progress that they could not reproduce their efforts in an acceptable amount of time, at a acceptable cost. There is typically nothing in dev that is so valuable as to be irreplaceable (unlike production, where the loss of 'yesterday's' data is extremely costly). Given the frequency that an offsite dev backup is actually required for a restore (seldom), and given that the value of the daily backed-up data is already so low, the actual risk cost is virtually zero.
I have never seen SAP publish a 'best practice' in this area. Every business is different; and I don't see how SAP could possibly make a meaningful recommendation that would fit yours. In your business, the risk (the pro-rata cost of infrequently needing to use offsite storage to replace or rebuild 'lost' low cost development work) may in fact outweigh the ongoing incremental costs of creating and maintaining offsite daily recovery media. Your company will have to perform that calculation to make the business decision. I personally have never seen a situation where daily offsite backup storage of dev was even close to making any kind of economic sense.

PL/SQL Design: Best Practice

Hello everybody,
I'm trying to improve myself acquiring compentence in PL/SQL design. At now I am (or I wish to be) a good practitioner but I have to complain myself for lackings in designing architecture.
I mean, for example, how to organize procedure and functions in a package, how to use pattern architecture, logging and testing practices...
Do you know where I can find resources for these arguments? Which books do you suggest to start with?
Thank you very much.
Nicola

The best practices are the very same fundamentals that apply to all other languages and have existed for since the dawn of programming.
The single biggest fundamental principle is to modularise your design and code. A well designed program consists of building blocks. Different languages have different names for these - procedures, functions, units, packages, methods, routines, etc.
A program lives or dies by how well it is modularised.
If you only get that right, you can claim to be a Programmer and not a mere two bit developer.
