Suggest Backup Strategy

Internal HD = 230GB
External HD 1 = 1TB (WD Home Edition) (USB, Fire Wire, eSATA)
External HD 2 = 1TB (WD Essential Edition) (USB)
Unused External Drives
150GB x 2 (USB or Fire Wire)
60GB (USB or Fire Wire)
Right now the WD HDs are a mirror RAID through OS X
All my data (work files, photos, music, movies, etc) saved to the mirror RAID
Now that I upgraded to Leopard, I set time machine to save on the mirror RAID as well. Time machine has been running for about a week now and the mirror RAID space is being used up. Eventually, there will be no more space before Time Machine begins to delete old backups. This will eat up my space for adding additional files.
Anything savable, is saved on the mirror RAID. The internal HD is only used for software.
Goals:
Keep a backup in a safe. (change it out every week or so)
Continue to use Time Machine.
Keep the savables in a separate drive than the Time Machine Drive
What is the best way to accomplish my goals? Anyone have suggestions to better the use of my drives?
thanks!

This will not work. Time Machine needs to have a volume dedicated to it. And, it sounds like all your files that would need to be backed up are also on this RAID volume... so, are you backing up from the RAID to the RAID? If so, that's a very bad idea!
Goals:
Keep a backup in a safe. (change it out every week or so)
Very good goal. However, be aware that a fire-proof safe is not a media safe. In the event of a fire, the temperatures reached inside the safe should not destroy paper, but they would destroy digital media. You'd be safer if you kept that extra copy off-site instead. Or you could buy a media safe, though they're more expensive. Of course, if you already have a media safe, all this is moot.
Continue to use Time Machine.
Keep the savables in a separate drive than the Time Machine Drive
With Time Machine, it's not the easiest to switch out drives, but you can do it. You just have to switch it manually in the settings every time, from what I understand. (I use Carbon Copy Cloner for my two duplicate on-site/off-site drives.) And you definitely want the TM drive to be a different one than the one the documents are on.
What is the best way to accomplish my goals? Anyone have suggestions to better the use of my drives?
Well, I'm not quite sure you can do that with the drives you've got. Your TM drive should be bigger than what you're storing on it. Many people recommend 2-3 times larger, but I don't believe that's a hard and fast rule... I think it depends more on the size of the files that will be modified between each backup. Your unused drives are definitely not large enough for any useful backups, unless you're not using TM and don't have those two TB drives anywhere close to full.
If you could buy another 1 TB drive, you could use one of your 1 TB drives for data and the other two as a striped (not mirrored) RAID could be the backup. Of course, this only gives you one backup, so you don't have anything to put in a safe.
OTOH, if you're nowhere near the 1 TB capacity in documents, you could buy a smaller drive (or use some combination of your unused drives) and use TM to back up to one of your 1 TB drives. Do that for a week, then put it in the safe and switch to the other 1 TB drive. You'll now have redundant backups, so even if something happens to the computer and the drive sitting beside it, you'll still have the other.
Good luck!

Oracle Suggested Backup, to tape only - Tivoli Storage Manager

I´ve been asked to cancel future backups to disk and to setup oracle´s suggested backup to the tape device only (which underwater is the tdpo from Tivoli´s storage manager).
This way the expensive disks can be freed from recovery data.
I´ve had my share of problems with the tdpo, but besides the problem of this gateway driver between RMAN and TSM I would like to know if this is best for the whole suggested backup strategy.
Somehow I´m not convinced in backing up to "tape" devices only; for it is slower than local disks, and because we had problems before with the driver, but there may be a lot more reasosn why I should or should not accept this desired goal to be best for our company.
I hope some of you can help me straighten my vision on this.
Robin

The biggest problems I think we might face are the
big question "who is responsible for what", and the
administration of non Oracle systems/methods to
perform backupsi have no problems with such a setup. i provide the rman skript which will be called by TSM.
the TSM admins notify me if the backup failed. retention on TSM side is disabled, only RMAN deletes obsolete/expired backups.
All I want to care about is performing a backup to
Disk, or Disk and Tape, or just Tape from within
Oracle/RMAN and read the ouput from here.
Now where these external tape labraries like TSM come
in there will be more administration for the total
handling of a backup job. It´s not only RMAN, but a
tdpo and a TSM server which need to be monitored
closely. of course TSM has to be monitored but if you already have invested an infrastructure you should use it for every type of backups.
Sadly Oracle has yet to come up with it´s secure
backup for TSM systems, but I think it would be best
if I could let Oracle solely in charge of its own
backups.if TSM retention is disabled, RMAN has absolute control.
Then again, I don´t know if anyone has good
experiences with TSM as the only backup provider for
Oracle backups. (so no disk backups)it works very good. use staged pools on TSM. primary pool should be diskpool, secondary a tapepool. you can configure TSM to move the data from disk to tape based on fill level or age.

RMAN Backup Strategy Comment Needed

Hi,
Currently I'm trying to implement a backup strategy with RMAN.
Scenario: My side we're 5 days operational (Monday to Friday). I'm planning my backup as follow:
Mon – Incremental level 1 differential
Tue – Incremental level 1 differential
Wed – Incremental level 1 cumulative
Thurs – Incremental level 1 differential
Fri – Incremental level 0 (aka full database backup)
I planned Mon,Tues and Thurs as an incremental differential, while Wed as an incremental cumulative. With Wed as a cumulative backup, my thinking is that if my db is to fail on Thurs/Fri, my recovery will need to apply fewer backups but at the expense of storage.
Any comment or view about the strategy will be greatly appreciated.
Thanks and Regards

Need Advice on Backup strategy

Hi,
Database version:10.2.0.
Database Size:60GB.
Daily Updation Approximately :2GB.
I need some advice on my backup strategy.
My backup startegy:
Monthly Once, Date: 1 Full backup (Incremental level 0).
Daily Incremental level 2 backup from Date: 2 to 6.
Weekly Once Incremental leve 1 backup on Date:7.
Daily Incremental level 2 backup from Date:8 to 13.
Weekly Incremental level 1 backup on Date:14.
Daily Incremental level 2 backup from Date:15 to 21.
Weekly Incremental level 1 backup on Date:22.
Daily Incremental level 2 backup from Date:23 to 28.
Weekly Incremental level 1 backup on Date:29.
My system requirments are i have only 70GB disk to store the backups, i can store only the full backup in it.So what i am doing is, Am storing the full backup in my disk and am transfering the Incrmental level 1(weekly Once backup) to the Tape and deleting the Daily level 2 backups, after taking that weekly backup.
Is my strategy correct or should i do anything different plz give me some advice.
TIA,

This backup strategy doesn't look bad. However the 70G of free space will be a pain in the neck. I suggest you to increase storage. Have you considered archivelog too? This average 2G daily transaction rate will increase storage requirements, sooner or later, so backup storage requirements.

Best practice PDW database backup strategy/plan

Hello All,
We are ready with PDW infra , appliance is almost ready. we are planning for implementation.
but before that , I have to document best practice for PDW database backup strategy/plan.
since PDW environment is pretty new . Please help me with best backup strategy/plan which can
be followed to implement in my proposed PDW solution.
your suggestions will be highly appreciated.

Hi Anish.S,
According to your description, you want to backup SQL Server Parallel Data Warehouse (PDW) database.
Before we get to the backup and restore syntax, it’s worth noting that the Parallel Data Warehouse (PDW) appliance architecture offers an environment that greatly enhances backup times (due to dedicated storage and network interfaces, see the following post
for more information -
https://saldeloera.wordpress.com/2012/07/09/lesson-1-of-parallel-data-warehouse-basic-architecture-overview/).
For more details how to backup and restore database on PDW, please refer to the following blog:

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

Synchronous multimaster replication Backup strategy using RMAN

Hi all,
I am using synchronous multimaster replication. my question is backup strategy has to perofirm in all the master site or only in any of 1 mastersite? what all problems will encounter in RMAn backup in my scenario please help me out with your suggestion
nagaraj.K
[email protected]

You ask: "I want to configure backup strategy using RMAN. any one can help me that"
And the answer is clearly no we can not.
An RMAN backup strategy depends on your SLA (Service Level Agreement) with your customers that you didn't post. What is your down-time window? What is your skill set?
You ask: "How to configure for RMAN Incremental backup?"
Read the docs at http://tahiti.oracle.com for your version (which you didn't mention).
You ask: "What will be backup space and there size ?"
We have no idea. Are you going to create an image copy or a backup set? Read the docs and learn the difference. Are you going to turn on compression? Are you going to back up only changed blocks? We don't know.
You ask: "how to manage growing online archiving files?"
Again we can't help you without knowing your SLA. How many MG/GB are they? What period of time do you need to retain them to meet your SLA? When you figure this out back up to tape those you don't need to keep on the server.
You ask: "how to manage growing data and there disk space?"
This is one we can answer: BUY MORE DISK! That was easy.
You ask: "How we can give good performance our CPU and memory?"
Do you really expect that we can with zero knowledge of your environment, your version, your application, etc. distill into a few short paragraphs the collective wisdom of Cary Millsap, Jonathan Lewis, and the rest of the Oak Table Network membership?
Of course we can not. So what you need to do is buy Cary's book, Jonathan's book, and take their classes.
You ask: "we need keep all archive log in backup files or we need to remove old archive files?"
Remove the old ones after being absolutely sure you have a good backup.
You ask: "where we can take backup tape drive,SAN,disk removable hard disk? which one is better?"
No one solution is better than the other. They are all adequate.

Backup strategy and hardware usage

I am trying to establish a backup policy for Small Business Suite 6.6
(netware 6.5). On Friday evening I do a daily backup scheduled at 10P but
on Saturday, I also do a Weekly backup of system files etc. Since these
are unattended backups, there is no one to change the tape for the weekly
backup. I have another server on line with identical hardware but I can
not see the tape drive of the second server from the first. Is there a
way to use the tape drive (server1)from server0 so I can put the two
tapes to be used in their respective drives before I leave on Friday
night? I am using Backup Exec 9.2 Any other suggestions on backup
strategy would also be appreciated.
Thanks, Roger

Roger -
I do the following 12-tape backup:
Mon - Thur, week 1 (4 tapes)
Mon - Thur, Week 2 (4 tapes)
Fri 1, Fri 2, etc (4 tapes).
The rare 5th Friday can be a problem in the first year, but... You reuse
year-old tapes as month-end tapes after the first year.
The Thursday tapes go out the door on Friday afternoon, meaning that they're
always at least one tape offsite. Month-end tapes go to a long-term storage
spot, either offsite or in a fire-proof safe.
I make a calendar at the beginning of the year for all my clients to help
them keep the tapes straight.
In addition, I use rsync to do an onsite backup to a NAS box (free software,
old workstation) as a second backup. It doesn't back up eDir, and of course
it doesn't go offsite, but it's quick and easy when you need to restore a
file or two!

Time Capsule backup strategy for multiple drives and OS

I'd like a backup strategy based on Time Capsule but have a few twists from a straightforward situation and would appreciate any guidance with setting it up. My hardware situation is:
- Two MacBooks, on 10.5, one with an 80 gb drive, the other with a 120 gb drive.
- One G4 iMac, on 10.4, with a 60 gb drive
- One LaCie NAS drive, used primarily as the storage space for music and video, and currently not backed up anywhere (making me nervous!)
Ideally I'd like each of these four units to be backed up on Time Capsule; and my configuration questions are in two areas:
1) Backup software: I'll use Time Machine to backup the MacBooks, but not sure about the G4 and NAS drive. These could be backed up on a more ad hoc basis (I don't need hourly updates). Is this best handled with a third party app like SuperDuper to allow for incremental backups?
2) Partition/disk image: is it wise (or indeed necessary) to create partitions for each of the above sources (I gather from reading other posts is seems the best way to achieve a partition is to create a disk image). I'm not sure if there would be any unintended consequences by doing so (or not),and if so if a sparse image disk image is better than a sparse bundle disk image given the above, so any guidance to help make sure it's set up as flexibly as possible from the outset would be greatly appreciated.
Thanks in advance for any advice.

G'day Michael,
Sounds like it is time to buy OS X Server!!!!
I think you are on the right track. As a "left field" suggestion, why not get two big drives, and use one of them as a file server. Get everyone to use the file server for any critical documents that they want backed up centrally/continuously. Then back the file server system up onto the other big drive using TM.
This reduces administration somewhat, and privacy can be retained with careful username management across the network.
Assuming that the three MacBooks are similarly configured from a system perspective, there is not a lot of point in having full bootable clone's of each one. Perhaps create a bootable clone from one of them each week - and clone the other two into disk images (which are not bootable, but are restorable) as frequently as needed.
Cheers,
Rodney

Regarding an External HD Backup Strategy...

I have tried some of the suggestions for a backup strategy and need more help. I partitioned the external drive (LaCie 250 GB via Firewire 800) into three volumes: one volume large enough for a clone of my internal HD, one volume for Mac OS X and TechTool Pro, and one for data.
1. When partitioning using Apple's Disk Utility, I could only choose one "option" for all volumes: the best options included "GUID Partition Table" (If I want to use that disk to start up an Intel-based Mac) or Apple Partition Map (If I want to use that drive as a non-startup disk with any Mac). I checked the box for Mac OS 9 drivers to be installed and chose the Apple Partition Map. I did this because I used SuperDuper! to clone my HD and checked the option to make that backup bootable (which is an option in SuperDuper). Is it still bootable on a non-GUID formatted drive? Are the Mac OS 9 drivers necessary? Does it hurt to have them?
2. When I install Mac OS X and TechTool Pro on the other volume, how do I make that volume bootable? When this is done, do I have to boot from this volume to update to 10.4.9? Will the Mac OS 9 drivers hinder this volume when I try to boot from it?
3. In case I do need to reformat using the GUID Partition Table, can I still store data on a volume that I don't intend to boot from? Should I still install the Mac OS 9 drivers if I am installing Mac OS X?
4. Is there a way to safely test these bootable volumes and the backup?
Thank you for your time and advice.

1. GUID is fine, but you don't need an OS9 drivers on an Intel Mac, no harm if they are on there.
2. At start up you hold down [option] and it will list all possible Boot volumes, select the one you wish to use.
3. Yes you can store data on any format, the main impact the format has in that case is whether the volume is read/write capable from Mac OS and/or Windows.
4. Once you've made your clone of the main hard drive onto the external volume, reboot holding down [option] and try booting from it ...

Long-term retention backup strategy for Oracle 10g

Hello,
I need design a Archivelog, Level 0 and Level 1 long-term retention backup strategy for Oracle 10g, It must be based in Rman with tapes.
¿Somebody could tell me what it's the best option to configure long-term retention backups in Oracle?, "CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 1825 DAYS;" It's posibble ?
Regards and thanks in advance

Hello;
RECOVERY WINDOW is an integer so yes its possible. Does it make sense?
Later My bad, this is Oracle 11 only ( the gavinsoorma link ) . Getting harder and harder to think about 10. Don't think I would use RECOVERY WINDOW.
I would let the tape backup system handle the retention of your rman backups.
Using crosscheck and delete expired commands you can keep the catalog current with the available backups on tape.
Oracle 10
Keeping a Long-Term Backup: Example

http://web.njit.edu/info/oracle/DOC/backup.102/b14191/advmaint005.htm
Oracle 11
If you want to keep 5 years worth of backups I might just use KEEP specific date using the UNTIL TIME clause :
keep until time 'sysdate+1825'More info :
RMAN KEEP FOREVER, KEEP UNTIL TIME and FORCE commands

Need help with backup strategy

So my 2 TB backup drive failed this morning. I'm using a Seagate drive in an OWC external enclosure. I plugged it in and the drive didn't pop-up on the desktop, nor is it visible in Disk Utility.
I know that all drives eventually fail, but it seems like I've had more than my fair share of problems lately. This is of course making me think hard about my backup strategy. Here's what I'm doing now - I'd appreciate your thoughts on how to make it even more "bulletproof".
> TimeMachine back-up of boot drive and media drive (with photos, documents, movies, etc.)
> External clone of boot drive and media drive (on two partitions) - this is the one that failed
I suppose I could add a third external clone for redundancy, but an offsite backup would probably be even better. Not quite sure what the best option is there, though. Any ideas?

I too love automation. However, an automated backup requires the backup drive to be always connected (and maybe powered) in order to perform the backup. Also, the computer you speak of must remain on (by the sounds of it) 24/7 in order to do a nightly back up at midnight.
First of all, it probably is not the best to leave your puter on 24/7. I won't go into all the OS reasons why. But here are 2 other reasons to think about:
1) Your internal HD will always be powered, bad on drives
2) You are constantly using power to run your system. Not good for your power bill or the greater environment
As for the always connected Backup HD- I only connect, and power on my backup when I go to do a backup. This leaves it disconnected in case of virus infection. And powered down/disconnected removes some of the risk of damage from power surges/spikes (yes I use a UPS, but these can/have failed)
So to sum up: I back up everyday. What I do is after I am done working in LR for the day I shut it down, and than start it back up (ugh) so that I can back up my Library with all the work I just did (wish Adobe would do a back up upon closing!!!)
Than I close down LR AGAIN..... Than I connect my Back up HD. Via usb, once connected it automatically powers up and fires up the back up software. All I do is hit start. Since this is an incremental back up it only takes a short while. I go use the "John" grab a drink, and come back unplug the Back up HD, and turn off the system for the day.

InfoProviders backup Strategy in SAP BW

Hello;
Does any one experienced a backup issue with BW especially when you would like to perform a risky modification. Is there any backup strategy that is supported by SAP for any modifcation senario, if it is a small modification or also a big one affecting one or more infoproviders. if there is any document please share with us.
Regards
Anis

Hi,
After the modification if you want original cube structure mean you need to roll back your transports with help of basis team. About roll back you cross check with basis team
Before doing the changes first have exact informations from your client or users.
If you think like that as need original cube structure then you can on copy cube structure at prod and move to dev thru transport.
When you need same or old cube structure, from dev you can move to prod or roll back option.
Thanks

How do i set up this backup strategy?

Hi All,
I am currently running Oracle Suggested Backups using RMAN. I set it up through enterprise manager. The Oracle suggested Backups took a level 0 backup two weeks ago and has been doing incremental backups everynight. Here is the RMAN script that runs nightly:
Daily Script:
run {
allocate channel oem_disk_backup device type disk;
recover copy of database with tag 'ORA$OEM_LEVEL_0';
backup incremental level 1 cumulative copies=1 for recover of copy with tag 'ORA$OEM_LEVEL_0' database;
I want to change this up. I want to take a full hot backup every week (sunday) and then do incremental backups each night. I also want to backup the archive logs and delete any files that are outside the retention policy. I want to keep 14 days worth of backups.
I want to set this up in enterprise manager. Do i have to set one weekly job on Sundays to take the full lev0 backup and then another job to run nightly to take the incremental backups? Can someone please put me on the right track?
I want to conserve disk space and currently all my archive logs and backup files are not being deleted.
Thanks,

Hi
Personally I don't think that it' s a good idea to set a retention polity to 14 days and delete the archive log if older than a week.
If you don't want to delete the archive logs that your are just backing up you can remove the world delete input from the above script.
run {
allocate channel ch1 type disk format '/db/ARON/BACKUP/RMAN/backup_%d_%t_%s_%p_%U.bck';
backupincremental level 0
database
plus archivelog;
backup current controlfile;
backup spfile;release channel ch1;
}If the backup was successful than I suggest you to program a script (UNIX shell ...) that delete the archive logs.
Using rman you can execute command like:
RMAN> delete archivelog until time "sysdate - 7" backed up 2 times to device type disk;
released channel: ORA_DISK_1
released channel: ORA_SBT_TAPE_1
allocated channel: ORA_DISK_1
channel ORA_DISK_1: sid=15 devtype=DISK
specification does not match any archive log in the recovery catalogor
RMAN> delete backup of archivelog until time "sysdate - 7" device type disk;
released channel: ORA_DISK_1
released channel: ORA_SBT_TAPE_1
allocated channel: ORA_DISK_1
channel ORA_DISK_1: sid=15 devtype=DISK
