Why Backup database then backup archivelog from time...

Dear Experts,
I found in one of our rman scripts the 2 following statements:
backup database;
backup archivelog from time 'SYSDATE -8';
It seems to me that a "backup database plus archivelog;" is more simple/accurate instead of these 2 lines as the retention windows is defined (5 days) for this DB so rman will manage the retention of datafiles and archived log, isn't it ?
Why this separate statement for the archivelog ? I find it redondant but is it...
Any advice is as usual greatly appreciated.
Best Regards,
Guillaume

You are right. The use of backup database plus archivelog; is much better and you are sure that you backup all archived log you need.
Probably that is an old script, previous version or the responsable of this script didn't know RMAN so good and the option you posted.
Bye, Aron

i want to ask about daily backup script.mainly (archivelog from time 'SYSDATE-3';),,,,,,,it is taking daily 3 days archivelog backup
what will be exact command instead of (archivelog from time 'SYSDATE-3';)

I assume you mean so that the daily doesn't constantly re-backup an archivelog that was already backed up?
If so, you could use the following:
run
backup as compressed backupset
device type disk
tag "daily_archivelog"
format '/sw/daily11_archivelog_%d_t%t_c%c_s%s_p%p'
archivelog all not backed up 1 times;
}or you could CONFIGURE BACKUP OPTIMIZATION ON or consider using DELETE INPUT to avoid the multiple backup of the same archivelogs.

Reinstall system to solve beachball issue, then get files from time machine backup.. will the bring beachball back

Hi,
My iMac has a beachball issue to the extent that now it not even starts up anymore, I don't even get to the desktop screen. I plan to reinstall the system from with the CD I got when I purchased the iMac 2 years ago, then update the operating system to the latest version, and then get my files and programs back from my latest time machine backup, which was completed c. 2 weeks ago.
1) Will this process generally work? I am running Mavericks 10.9, so the CD I want to install from will be an older version, but I then plan to upgrade to 10.9 before accessing the time machine files.
2) Post upgrading the op system to the latest version, when I then get the programs and files back from time machine, will that bring also back the beach ball issue, or given that everything will be saved and installed 'cleanly' it will be alright?
I am not a mac pro, so still learning, please forgive if I am not posting required info. Let me know what you need.
Thanks

1. Yes.
2. Depending on what is causing the beachball, restoring may or may not bring the problem back.

HT1751 words is iTunes set up to do this , or do I have to use AppData...Backup directory then re-direct from there?

Does iTunes offer any functionality for permanet backup to external hard drive? Or, do we have to just copy files form AppData...Backup, re-direct, etc?
This is on a Windows Vista machine.

See this backup tip. The main thing to backup is your iTunes library. Although you can also backup the device backup sets reintegrating these into iTunes isn't easy. In the event of a problem it is best to restore/migrate the library to an new/rebuilt machine and then immediately backup your devices rather than attempting to move the iOS backups. Note that iTunes normal maintains one rolling backup of each device. I've just discovered that Mac users can optionally archive these but for Windows user the only way to do the same thing is to backup and then immediately restore the device. Doing this every month or so gives you a chance to recover if don't discover a problem until after you've backed up a device.

Office 2011 for Mac - Error rebuilding database following full restore from Time machine

This is my first time on here, so will try to be brief and specific.
I have been using Outlook without issues. I had a logic board failure and had to replace my logic board on my Macbook pro.
After repair, I then restored the entire computer from my Time machine backup
Everything worked perfectly until I tried to use Outlook, when I was given an error message saying "Your Office database index is missing and needs to be rebuilt. This is usually caused by restoring an identity with Time Machine." It then offers
me a chance to rebuild using the Database Utility.
I went ahead and tried to rebuild, but after running through the 5 steps, the task failed and I was given another error msg: :Your database could not be rebuilt [-18000]
I did some research online and found an article which suggested I go back in time on my Time machine and find an old version of my 'Main Identity' folder from when Outlook was working. Then to copy that folder,
rename it 'Restored Main Identity' and paste it into the 'Office 2011 Identities' folder on my HD.
I have done that, so it now appears with the other identities in the Microsoft Database Utility, and then tried to rebuild again, but still no luck.
Any ideas on how I can get around this issue…. don't really understand how Outlook is the only thing that I can't get working after restoring my old data.
Tried to get some help from Microsoft, but they pointed me to this forum or wanted to charge me for advice…
Any help would be much appreciated,
Paul

Why does restoring a Hard Drive from Time Machine break all my software registration?

I've just upgraded the hard drive in my MacBook Pro using a Time Machine backup. (In the past I've used Carbon Copy cloner to duplicate the drive before installing it, but this seemed like an easier option.) The restore from TM went fine... but now all my apps are acting as if I've just installed them for the first time. Mail and Dropbox went thru their first time startup screens, and are reimporting all my files/messages. Word and Photoshop are asking for the registration serial numbers. What a hassle!
Does anyone know what Time Machine is doing, and why? Why aren't my apps fully restored? And is there any workaround?

I imagine it is because of the way CCC does makes an exact clone of your drive.
Time Machine restores the drive file-by-file and doesn't necessarily restore support files. Most apps know when they've been moved and ask for serial numbers.
However, I have never restored a complete hard drive with Time Machine, so I don't know exactly what to expect.
Pondini may have some info here: http://pondini.org/TM/14.html

How to full restore OS X state to a specific date from Time Machine backup?

Hello! Could someone please advice how to restore the state of my iMac to a specific date?
NOT to the latest backup?

The only way I found to make a full restoration of OS X to specific date from a TM backup is to launch OS X in recovery mode (Cmd+R during startup) and then choose "Recover from Time Machine". Full restoration took approx 2 hours.
Dislike it very much. During my being a Windows user I could roll back in a matter of minutes with system utilities

Can't backup database in NOarchivelog mode

I altered it in archivelog mode.
Now I can run a backup database command from rman?What does it cost to try it and see? What would be the worst thing that could possibly happen? An error message saying you can't do that?
And please note, this forum is not a chat line. Operators are NOT standing by. Posting a new message every two minutes to give an update on the fact that the database hasn't shut down yet is not necessary and not productive.
If there are a lot of pending transactions when you issue SHUTDOWN IMMEDIATE, they will all have to be rolled back as part of the shutdown. That can take some time. And if you bypass that with SHUTDOWN ABORT, they will have to be rolled back as part of instance crash recovery on the next startup, which will also take some time. Five minutes may feel like an eternity when you are sitting there waiting for your command to complete, but is no reason to panic.

Create server role for backups (BACKUP DATABASE and RESTORE HEADERONLY)

Hello-
I wish to create a server role that will allow any users assigned to it to be able to issue a BACKUP DATABASE and RESTORE HEADERONLY for any database on the server. I've been searching Google and MSDN but haven't had much luck. I can create the
user (CREATE SERVER ROLE backupuser;) but don't really know how to assign the permissions to it that I want. I wish to keep the permissions as narrow as possible for good practice; I could just assign the user to the sysadmin group but that shouldn't
be necessary.
If anyone can help, I would much appreciate it.

Whenever you need to find out the required permissions for a command, the best way is to look up these commands in Books Online, and to the Permissions/Securities section. This is what I always do when people asks these questions, because I rarely knows
the answer by heart.
So, let's see what the topic for BACKUP has to say:
   BACKUP DATABASE and BACKUP LOG permissions default to members of the
   sysadmin fixed server role and the db_owner and db_backupoperator fixed
   database roles
The permission section for RESTORE HEADERONLY says:
   Beginning in SQL Server 2008, obtaining information about a backup set or
   backup device requires CREATE DATABASE permission. For more information,
   see GRANT Database Permissions (Transact-SQL).
So it seems that if you want a user that has server-level rights to back up databases, this must be sysadmin, which is a little disappointing. One possibility is to package the BACKUP command in a stored procedure, which you sign with a certificate. Then
you create a login from the certiticate, and add that login to sysadmin. BACKUP accepts parameters for many of its arguments, so you don't have to build dynamic SQL. Still it is not really a satisfactory solution, since this user will have to work with
BACKUP "commands" that will be procedure calls.

Would you use scripts to take database out of archivelog mode?

Background: we do not use RMAN for this production database and we do cold backups each night.
I've been asked to take one of our databases out of archivelog mode for a few days and then to put it back into archivelog mode.
Being somewhat neurotic about these things - I've only ever done it manually - so that I can make sure nothing goes wrong and to check that there was a last successful cold backup prior to the switch.
However, management have asked that it be done automatically by scripts after the backup.
Whilst I can create a script that will do this - the question I'd like to ask the forum is - have you and would you?

I do not agree with taking any Oracle database out of archivelog mode and I do not approve of management's decision and have told them why and all the risks they run.
This is not a test database - it IS a production database and other users do make changes daily.
What I did not reveal until now is that I have also been asked to take this database out of archivelog mode for 5 days and suspend all cold back-ups for the whole server (with 3 other instances on the server - also impacted) - and have warned them accordingly.
However, management have been swayed by someone who feels they know better - who claims to be a qualified Oracle DBA - I'm OCP but seems to have little sway since this person has convinced management that my 6 years experience and qualification is less than his application experience in GIS.
They want to run an upload which will take around 5 days to do - I'm somewhat miffed that an upload can take that length of time and question whether a GIS system should need such an upload for such a length of time.
Let's no go into the problem with tablespaces and space within the tablespaces - the upload will fail because they do not understand that if the tablespace fills up - the upload will fail - but despite asking - I've been told that there is no problem - there will be a problem - since I refuse to allow autoextend on this database - because of the potential to run out of disk space.
I've explained until I'm blue in the face - never mind that even if the upload is successful - the cold backup tape won't be able to backup the data because it'll be potentially over the limit.
I've even warned of my past experience x 3 - when a RAID controller failed - literally died in front of my eyes - I just happened to be standing next to one of the servers talking to someone - and the whole server was lost - but because we had the archivelogs - and the previous day's backup - we got it up and running after Dell replaced the RAID controller - within 1 hour.
That's the joy of Oracle - nothing is lost other than the last archivelog - depending on the time you set the switch.
I love this system - it's so recoverable - it such a joy to work with.
But then when I get told to suspend cold backups and then at the same time suspend archivelog mode - I go mad.
Don't get me started - I've gone down the usual path of why hire an OCP when you won't listen to what I say, etc.
Management are demanding I switch it automatically out of archivelog mode etc.
I can do it - but my question is still - have you guys?
And why did you do it?
All I can say is that I hope that the server has a RAID contoller failure and finally they listen to me - the chances of that are minimal - so management are saying - do it or else.
Oh and by the way - the GIS team have asked for this to be bi-monthly - automated.
And have said that:
"You can not rollback or recover the loading process using the log files because it involves a far more complex operation that would most likely not be successful."
Nice phrase that to an OCP.
I welcome your comments - as I really am in a hole here.
Thanks.

IMac won't startup after restore from time machine

After I restore my backup from time machine ( twice ) mi iMac halt at startup and won't startup. It stuck at the apple logo forever. I also restarted holding down command R safe mode and install OS X and it will startup okay but can't see my buck up files and applications here. Then I restore from time machine again using an earlier backup and it won't startup again. Please any help I will appreciate.

There could be a few reasons for this.
First what version of OS X do you have installed?
What version of OS X is the Time Machine Backup file from?
Did Reinstalling OS X from Recovery install the same version you had before reinstalling?
If you have not changed OS X versions then:
It sounds like there may be a bad file in the backup that is causing the computer to not startup after restoring it. This is especailly true if the computer boots just fine after a fresh installation of OS X, but without the Migrated Data being restored.
If that is the case, then the solution is not a quick one. You have to hunt down the bad file.
Moving Files Manually (Not in Migration Assistant)
Manually access your Time Machine backup folder from within Finder (you should see the backup drive in a Finder Window or on your Desktop). Once open, manually move data from the User folder (documents, music, movies, photos etc.) into their respective folders on the Mac. Reboot after each folder you move to see which folder contains the corrupted file then delete the affected folder/file after reinstalling OS X from Recovery.
If none of the files cause the computer to hang at startup after moving all your User data, then the issue is from within the System or Library folders.
NOTE: DO NOT manually move Applications, System, or System Library files over to the Mac. You can cause major issues with the current installation by doing so. It is safer to just reinstall all the Apps from wherever you got them so they can recreate their support files and such themselves.
2- Using Migration Assistant
Basically, if you have discovered the affected file. You can just simply delete it from the backup folder.
Reinstall OS X after you have done that, and use Migration Assistant to automatically migrate the data over minus the affected file/folder.
Its a pain in the rear, but it will at least let you salvage most of your data.
Let me know what happens riorec!

Going back to leopard from snow leopard Can I restore from Time machine

My Imac continues to lock up about three times a day since I went to Snow Leopard.
I want to go back to Leopard where I did not have these problems.
Can I reformat and do a clean install and then restore everything from time machine even though the back up is from Snow Leopard?

You can restore the system to any previous dated state shown in your Time Machine backups. However, this will not preserve anything you created after that date. You can also restore individual files & folders from later backups but you may or may not be able to use files you created using Snow Leopard while running Leopard, depending on the parent application & if it was updated to use a new file format with Snow Leopard.
It is generally much better to resolve the issues you have with Snow Leopard & continue using it than to try to do this. Most issues are fairly easy to resolve. If you want help with that, let us know.
