Is this the backup strategy easily recoverable??

hi,
I m not good at backup recovery tasks, i have to set an AUTO backup strategy for HOTEL MANAGEMENT SYSTEM in ORACLE 11g R2.
the strategy is:
The database is in archive log mode, the backup is through backup set.
Weekly 1 full online backup at night and daily incremental backup of datafiles,control file, spfile and archives.
is this the backup strategy easily recoverable and how??

is this the backup strategy easily recoverable and how??It's easily recoverable - if you have properly protected your backupsets and if you have practiced several different recovery scenarios. And by "practice" I mean actual, hands on recovery in a test environment. 2:00 am with the production system down is not the time to start "practice" or to discover some weakness in your backup strategy.
And the fact that it is a HOTEL MANAGEMENT SYSTEM (why the shouting, btw) is really irrelevant. To oracle, it's all just data. Hotel management data is no different than automobile manufacturing data.

The backup strategy

What would be the backup strategy for the following database:
Documentum application. The database keeps references to the files on filesystem. Both database and filesystem with documents should be in sync.
Using only the RMAN probably not the perfect solution here; I do not know whether it is possible to backup plain filesystem from it.
So far, I end up creating snapshots of the database and documents' file-structure when the database in hot-backup mode or down. The snapshot is the feature of the NetApp filer and once created it can be backed up on a conventional way by copying files to the backup media. The creation of the snapshot is also instantaneous so the down time for the application and database is minimal. The disadvantage of such method is in complicated recovery, but I did not find anything better than this so far. Any ideas will be appreciated.

Leonid

Hi.To building backup recovery strategy depend some reasons.This strategy must prevent and safe your database against media fails(disk problem) user fails(human errors).Therefore firstly place your database in archivelog mode as:
sqlplus "/as sysdba"
shutdown immediate;
startup mount;
alter system set db_recovery_file_dest='flash_recovery_area'
/*(recommended that backups including all archivelogs placed in FRA)*/
alter database archivelog;
alter database open; Also you can take every day incremental backup using RMAN and weekend you can take full(level 0) backup
rman target /
run{
backup incremantal level 1 for recover of copy with tag 'incr_db' database ;
recover copy of database with tag 'incr_db';
}and enable flashback on for user errors.In additionally you can use dataguard,create standby database.Using this way you prevent your database against disasters. For more information see below links;

What is the backup strategy for your rpool?

Hi all,
May I know what is your backup strategy for rpool? like how to integrate with the netbackup or any other backup software
Is it using zfs send a data stream to a file and backup that file using backup software??
Aside the above method, can we also use the UFS method?
     backup software to backup entire / /var.......... etc....
     1. re install the OS
     2. install the backup client
     3. create a zpool (rpool-restore) using a 2nd disk,
     4. mount the new zpool (rpool-restore) to /restore
     5. restore all the file in /restore
     6. install boot blk,
     7. boot from 2nd disk
Any more idea?

HI Willy,
According to the Flash Archives limitation stated in Oracle website, if the OS is with a child zone, it will not work right?
http://docs.oracle.com/cd/E19253-01/821-0436/6nlg6fi8u/index.html
I am thinking that using the traditional way to do it.
Use a backup software, for example, networker, TSM, netbackup.. to back up the following:
/rpool
/export/
/export/home
     1. re install the OS
     2. install the backup client
     3. create a zpool (rpool-restore) using a 2nd disk,
     4. mount the new zpool (rpool-restore) to /restore
     5. restore all the file in /restore
     6. install boot blk,
     7. boot from 2nd disk
will it still works?

Backup strategy for ebs R12?

Hi,
I have a couple of questions regarding to backup strategy for ebs R12.
Let's say that we have one application server and one database server running, and we would like to have a backup periodically for both servers.
This means that we want to have the exactly same backup of configurations and other files for the application server and the database server in case of any fatal crashes in the servers.
I went through some discussion threads and it seems common way is to use RMAN for the data of database and file system copy for application and database servers. But, I would like to know what's the best way or recommended way for the backup strategy for data and server files of Oracle e-business suite.
Do you guys have any suggestion for this?
Thanks in advance.
Cheers,
SH

Hi SH;
I suggest check first our previous discussion
backup and recovery startegy for EBS
Re: Backup System
Backup Policy for EBS can
If you make search you can find many other thread which is mention same question
For your issue basicly what we do
1. For our prod db, if possible we take weekly cold backup(sunday) and take rman backup also daily(full backup, but it depends system you can prefer to take incremental)
2. For our system we take file system backup weekly(OS base)
3. For application we take backup every sunday(for some system 15 days or 30 days period). The most important point here if your system prod, and if you need to apply patch to your system you need to have valid backup and also need backup for after patching
One other important issue is we run preclone sh before take backup for apps and db tier

SMD Diagnostics Agent Backup Strategy?

Posting this question here as well as the Solution Manager forum since we're running SAP on the iSeries.
My organization has just started deploying SMD agents across our SAP landscape and we're considering how this new component (the agent) fits in our backup strategy. Should the agents even be included in our periods backups? They're small, easy to reinstall if necessary, and don't store any data, but would have to be re-registered. Any other backup consideration? We're interested in how other organizations have dealt with this question, thanks for your input!
Robert Garst
Perrigo SAP Basis Team

Hi Robert,
as you already supposed I wouldn't include SMD agents in the backup strategy since they are little and don't store data. What's important is the central Solution Manager System itself. There the data reported by SMD agents is used and stored.
Best regards,
Christoph

Questions on Oracle EBS backup strategy

Hi all,
Currently I am planning the backup strategy for the EBS. May I know apart from backup the database using RMAN, is there anything (e.g. log files) that I need to backup such that I can fully restore the system?
Thanks a lot in advance.
Alex

I see that this is your first post, and you have not searched on this forum or on google about n-number of responses to your question that various people have already asked.
You didn't mentioned the applicaiton version you are using.
Anyways, you need to take the complete backup of the application tier directories i.e., appl_top, common_top, inst_top, etc.

Defining a backup strategy

Hello all,
I have to help someone to implement a backup strategy on a database.
Before defining the backup strategy I'm doing a document with some questions that the clients needs to answer, so I can recommend the most adequate backup strategy.
I will leave here the questions that I think are useful to ask. Please help me out with this by correcting or adding or discussing questions:
Questions to the client:
- What type of database do you have (data warehouse, transactional,...)?
- Whats the size of the database and what is the expected growth per month/ year ?
- How much information is inserted/updated into the database per day/month?
- What type of backups do you need? daily? weekly? ...
- What MTTR (mean time to recover/repair) do you need for the database?
- How will the backups be done? to the hard drive? to tape? ....
- Do you have a backup agent? If so, witch one do you have? Does the agent has its own scripts or do we need to create them ourself.
- Does the database works 24x7, or can it have any downtime for backup?
I really apreciate you help.

A good start point is the reading of Best Practices for Oracle Database 10g Backup and Recovery which discuss against three important questions :
• How quickly should recovery complete for a datafile, tablespace, and database?
• What is the tolerance for data loss?
• How far back should backups be kept to satisfy the data retention policy?

HT3275 The backup disk image "/Volumes/Data/Macintosh.sparsebundle" is already in use.

What do I do to fix this: The backup disk image “/Volumes/Data/Macintosh.sparsebundle” is already in use.

Pull the power cord from the back of the Time Capsule
Count to 10
Plug the power cord back in to the back of the Time Capsule
This simple reset will fix this bug 98% of the time. If you are in the 2% category, see this excellent support document for more fixes.

Error: "This backup is too large for the backup volume."

Well TM is acting up. I get an error that reads:
"This backup is too large for the backup volume."
Both the internal boot disk and the external baclup drive are 1TB. The internal one has a two partitions, the OSX one that is 900GBs and a 32GB NTFS one for Boot Camp.
The external drive is a single OSX Extended part. that is 932GBs.
Both the Time Machine disk, and the Boot Camp disk are excluded from the backup along with a "Crap" folder for temporary large files as well as the EyeTV temp folder.
Time Machine says it needs 938GBs to backup only the OSX disk, which has 806GBs in use with the rest free. WTFFF? The TM pane says that "only" 782GBs are going to be backed up. Where did the 938GBs figure come from?
This happened after moving a large folder (128GB in total) from the root of the OSX disk over to my Home Folder.
I have reformated the Time Machine drive and have no backups at all of my data and it refuses to backup!!
Why would it need 938GBs of space to backup if the disk has "only" 806 GBs in use??? Is there anyway to reset Time Machine completely???

TM makes an initial "estimate" of how much space it needs, "including padding", that is often quite high. Why that is, and Just exactly what it means by "padding" are rather mysterious. But it does also need work space on any drive, including your TM drive.
But beyond that, your TM disk really is too small for what you're backing-up. The general "rule of thumb" is it should be 2-3 times the size of what it's backing-up, but it really depends on how you use your Mac. If you frequently update lots of large files, even 3 times may not be enough. If you're a light user, you might get by with 1.5 times. But that's about the lower limit.
Note that although it does skip a few system caches, work files, etc., by default it backs up everything else, and does not do any compression.
All this is because TM is designed to manage it's backups and space for you. Once it's initial, full backup is done, it will by default then back-up any changes hourly. It only keeps those hourly backups for 24 hours, but converts the first of the day to a "daily" backup, which it keeps for a month. After a month, it converts one per week into a "weekly" backup that it will keep for as long as it has room
What you're up against is, room for those 30 dailies and up to 24 hourlies.
You might be able to get it to work, sort of, temporarily, by excluding something large, like your home folder, until that first full backup completes, then remove the exclusion for the next run. But pretty soon, it will begin to fail again, and you'll have to delete backups manually (from the TM interface, not via the Finder).
Longer term, you need a bigger disk; or exclude some large items (back-them up to a portable external or even DVD/RWs first); or a different strategy.
You might want to investigate CarbonCopyCloner, SuperDuper!, and other apps that can be used to make bootable "clones". Their advantage, beyond needing less room, is when your HD fails, you can immediately boot and run from the clone, rather than waiting to restore from TM to your repaired or replaced HD.
Their disadvantages are, you don't have the previous versions of changed or deleted files, and because of the way they work, their "incremental" backups of changed items take much longer and far more CPU.
Many of us use both a "clone" (I use CCC) and TM. On my small (roughly 30 gb) system, the difference is dramatic: I rarely notice TM's hourly backups -- they usually run under 30 seconds; CCC takes at least 15 minutes and most of my CPU.

"This backup is too large for the backup disk" WHY?

My iMac has a 2tb internal drive.
I got a 4th gen 2tb Time Capsule to back it up.
Problem is I get this message - "This backup is too large for the backup disk. The backup requires 2.10 TB but only 2.00 TB are available." WHY?
My internal drive is using 1.75gb of 2tb. Time Capsule is 4th gen 2tb, firmware up to date.
2nd Question - can the WAN and/or wifi ports be easily replaced if they are faulty on another Time Capsule?

Sorry, but that's too small.
Since Time Machine keeps copies of things that have been changed or deleted, it needs much more space than the data it's backing-up. See Time Machine - Frequently Asked Question #1.
Your options are not good. You can connect a larger USB drive and back up to that instead, but I'm not sure how large a drive the TC can handle. It would probably need a powered hub, as the USB port is underpowered.
Or, you could use a different backup app. CarbonCopyCloner and ChronoSync might be workable alteratives.
Problem is I get this message - "This backup is too large for the backup disk. The backup requires 2.10 TB but only 2.00 TB are available." WHY?
It adds "padding" in case the initial estimate is too low, and for workspace on the destination.

HT201269 itunes cannot see my iphone backup. I have a backup of the backup on an external HD, but even tech support cannot figure this one out. I copy and paste backups into the correct folder but itunes still does not see it. All I need are my contact

Sorry for short novel I am writing. I just wanted to cover as much backround as possible.
So, here it goes. I backed up my iphone 4 after renting a movie. The movie only played the starting credits before I was called on for daddy duty. A few days later the movie would not play, so I restored my phone from my backup. The movie would still would not play so itunes support refunded my purchase and ended my viewing privileges for that rental after verifying that I had not viewed the movie. I then had a problem with my contacts showing up twice in the contacts list after the restore. So I attempted another restore. All was well at this point. I then started having trouble with my pc and decided to copy the internal drive to an external source. A week later I had a system failure and did a factory restore on my computer. I re-installed itunes and tried to copy and paste the old backup into the new itunes. Now itunes just flat out does not see the backup file (I failed to mention that I did a factory reset on the iphone after the last backup, hopping to start fresh). Tech support had me uninstall and re-install itunes and then copy and paste the old backup into the newly installed itunes with no luck. The files are all there, but itunes just doesn't see them (itunes says the device has not been backed up to the cloud or to the local machine). We then tried backing up the factory restored iphone and replacing that restore file with one of my old backups on the external drive. Ok, this is where it gets weird. We replaced the guts of the folder but left the folder itself so itunes would continue to recognize the new backup folder with the old files. Whoohoo, itunes now see's a backup folder full of old files, or so we thought. The new files were deleted using shift delete so they would be gone for good and not mix with any files or folders. When I restore my phone, it restores the files that were deleted from the restore file (pause here for a moment and imagine the stupid look on the face of tech support and I while we silently wonder how files that were permanently deleted were restored). This left tech support and I both scratching our heads. My service issue was escalated to the next level. I waited for the phone call the next day that was scheduled at 10am to my wife's phone, but the call never came through. As usual, apple disappoints again. I just bought an iphone 5s and still have the iphone 4, and am looking for a solution to retrieve my contacts and restore to the 4 or 5s. I am guessing that files in other folders must be associated with the iphone backup in order for itunes to retrieve the files. Any ideas or support in retrieving my contacts would be greatly appreciated.

Recently backing up my ipad onto my macbook, which is the backup server for all of my gadgets. This includes all my photos and tons of music. The macbook said it could not backup the ipad because there was insufficient disc space to do so. What now?

I have a macbook operating OSX10.6.7. Recently backing up my ipad which had lots of photos from a recent vacation. I use this laptop as the backup server for all of my gadgets so it has thousands of photos and tons of music. It just told me that it couldn't back up the ipad bc there wasn't enough disc space. I was afraid that this would happen eventually. What next? Newer laptop with more space? I'm not sure what files I could sacrifice to free up more space as most of these are important.

What size hard drive do you have in your MacBook? The cheapest options are, a larger internal hard drive, or an external drive. Or you could get a cheap desktop PC and network to it for storage. I've got one that lives in the hall with 3 Terabytes (That's 3000gb) of storage.

Can someone help.
I tried doing my backup restore on the same computer as I once did a year ago. and THis time I cant do the restore on the iphone.
computer osx is 10.5.8
itunes version 10.
I do not wish to go to ios 7 at this time.

Settings > General > Reset > Reset Network Settings.
Basic troubleshooting is reset, restart, restore (first from backup then as new). Try each of these in order until the issue is resolved.
If the issue continues, contact the carrier to troubleshoot the network connectivity issues.

I don't understand stage 5: how and where do I select the disk or volume that contains Time Machine backups ? How do I know which it is? My disk utility lists 160.04 TOSHIBA MK... with sub-heading Macintosh HD. It also lists (with a "CD" icon) HL-DT-ST DVDRW GS22N

Mac Help says:
If you back up to a Time Capsule or network disk:
Open the Time Machine pane of System Preferences, and slide the switch to Off.
Open Time Machine preferences
Open Disk Utility, which is in the Utilities folder in the Applications folder.
Open Disk Utility
Make sure the Time Capsule or network disk is turned on and available.
Open a Finder window, select your Time Capsule or network disk in the Shared section of the sidebar, and click Connect. If necessary, enter your user name and password.
On the Time Capsule or network disk, select the disk or volume that contains Time Machine backups. Depending on how your Time Capsule is set up, there may be one or more disks or volumes.
Locate your backup, and drag it to the Disk Utility sidebar.You can identify your backup by looking for your computer’s name in the backup’s filename.
