RAID Backup Schema?

I've a Mac Pro with the default 250GB HDD as the system drive. I also added a RAID 0 with two 400 GB WD HDDs giving me a fairly fast 745GB secondary 'drive' that I use for most of my larger projects.
I realize that I've now doubled the chances of a HDD failure wiping out my data. In fact it was made very obvious to me when I came in to my office one morning to find the RAID drive gone. Disk Utility wouldn't even boot up. I restarted the computer and still had nothing. At this point Disk Utility told me that there was only one of the two physical drives installed. I shut down again, pulled both disks out and reseated them in the same bays. Upon restart, voila, I was back in business and scared to death of it happening again.
I immediately ordered a 750 GB HDD to go in the fourth bay and to be dedicated to backing up the RAID. So here's my question: what would the experts suggest here as the best way to go about ensuring I'm able to keep my data safe?
I believe a RAID 10 requires 4 identical drives. My third drive is nearly twice the size of the individual RAID 0 drives but I don't think it works that way. Should I just use something like Retrospect/Backup/Lacie Silverlining to do a nightly backup or sync of the RAID to the new 750 GB drive?
Any suggestions?
Thanks much in advance.

Basic Backup
My personal recommendations are (order is not significant):
1. Retrospect Desktop (Commercial - not yet universal binary)
2. Synchronize! Pro X (Commercial)
3. Synk (Backup, Standard, or Pro)
4. Deja Vu (Shareware)
5. PsynchX 2.1.1 and RsyncX 2.1 (Freeware)
6. Carbon Copy Cloner (Freeware - 3.0 is a Universal Binary)
7. SuperDuper! (Commercial)
The following utilities can also be used for backup, but cannot create bootable clones:
1. Backup (requires a .Mac account with Apple both to get the software and to use it.)
2. Toast
3. Impression
4. arRSync
Apple's Backup is a full backup tool capable of also backing up across multiple media such as CD/DVD. However, it cannot create bootable backups. It is primarily an "archiving" utility as are the other two.

Using expdp/impdp to backup schemas to new tablespace

Hello,
I have tablespace A for schemas A1 and A2, and I wish back up these schemes to tablespace B using schema names B1 and B2 (so the contents of schemas A1 and A2 are copied into schemas B1 and B2, respectively, to use as backups in case something happens to schemas A1 or A2 or tablespace A).
I began by creating tablespace B, and schemas B1 and B2. Then I attempted to populate schemas B1 and B2 by doing the following:
EXPORT SCHEMAS:
expdp a1/a1password@myIdentifier ESTIMATE=BLOCKS DUMPFILE=myDpumpDirectory:a1.dmp LOGFILE=myDpumpDirectory:a1_export.log SCHEMAS=a1 COMPRESSION=METADATA_ONLY
expdp a2/a2password@myIdentifier ESTIMATE=BLOCKS DUMPFILE=myDpumpDirectory:a2.dmp LOGFILE=myDpumpDirectory:a2_export.log SCHEMAS=a2 COMPRESSION=METADATA_ONLY
IMPORT SCHEMAS:
impdp b1/b1password@myIdentifier DUMPFILE=myDpumpDirectory:a1.dmp LOGFILE=myDpumpDirectory:b1_import.log REMAP_SCHEMA=a1:b1
impdp b2/b2password@myIdentifier DUMPFILE=myDpumpDirectory:a2.dmp LOGFILE=myDpumpDirectory:b2_import.log REMAP_SCHEMA=a2:b2
This resulted in backing up schema A1 into schema B1, and schema A2 into B2, but the tablespaces for schemas B1 and B2 remained tablespace A (when I wanted them to be tablespace B).
I will drop schemas B1 and B2, create new schemas, and try again. What command should I use to get the tablespace correct this time?
Reviewing the documentation for data pump import
http://docs.oracle.com/cd/E11882_01/server.112/e22490/dp_import.htm#SUTIL300
specifically the section titled REMAP_TABLESPACE, I'm thinking that I could just add a switch to the above import commands to remap tablespace, such as:
impdp b1/b1password@myIdentifier DUMPFILE=myDpumpDirectory:a1.dmp LOGFILE=myDpumpDirectory:b1_import.log REMAP_SCHEMA=a1:b1 REMAP_TABLESPACE=a:b
impdp b2/b2password@myIdentifier DUMPFILE=myDpumpDirectory:a2.dmp LOGFILE=myDpumpDirectory:b2_import.log REMAP_SCHEMA=a2:b2 REMAP_TABLESPACE=a:b
Is that correct?
Also, is it OK to use the same export commands above, or should they change to support the REMAP_TABLESPACE?

Hi,
if i understand correctly, you want to import A1:B1 and A2:B2 with the Respective Tablespace. You are using the expdp with ESTIMATE it can not help you
You can use something like that with one dump file
expdp system/password directory=<myDpumpDirectory> dumpfile=A1_A2_Export.dmp logfile=A1_A2_Export.log schemas=A1,A2
impdp system/password directory=<myDpumpDirectory> dumpfile=A1_A2_Export.dmp logfile=A1_A2_Import.log remap_schemas=<A1:B1,A2:B2> REMAP_TABLESPACE=<TAB1:TAB2>

Times Machine backup scheme

I run a small office with three machines:
new Core i5 iMac, just purchased, (refurbished from Apple) running MacOS 10.8 (1 TB HDD)
Macbook, first generation, running MacOS 10.6.8 (160 GB HDD)
G4 iMac, used as a file server, being slowly phased out of use, running MacOS 10.4.11 & 9.2.2 "classic mode" (300 GB HDD)
I also store a common iPhoto library on a LaCie Rugged 300 GB hard disk, which will go back and forth between the new iMac and the MacBook.
My Time Machine questions:
I plan to use LaCie's SilverKeeper backup utility to back up the G4 iMac and the LaCie iPhoto drive, so they are not relevant.
My concern is with the newer iMac and the Macbook. Currently, the greatest capacity I have on an external hard drive is 500 GB. If I plug the new iMac into a 500 GB hard disk and start up Time Machine, will the Time Machine back up process really work? I do not have anywhere near 1 TB of data to back up. In fact, up until recently, the new iMac's predecessor was a (now dead) MacBook Pro and I was able to back up both laptops, the G4 iMac and the iPhoto drive on one 500 GB hard drive.
The other concern I have: I studied Time Machine on both Lynda.com and on my old MacBook Pro before it died. (It ran MacOS 10.6.8) I'm a little confused. Can a single backup drive be used to store Time Machine backups between two or more computers? It looks like Time Machine wants to use an entire hard drive per computer. Can I partition an external drive to have more than one mountable volume available for periodic Time Machine backups? Also: has the Time Machine interface changed significantly from MacOS 10.6 ("Snow Leopard") to today's 10.8 ("Mountain Lion")?
I've been hunting for deals on the internet for new backup hard drives. Does anyone here use cheap, USB-only portable bus-powered hard drives (like LaCie's Rugged drives) for easily carried, easily stowed Time Machine backup drives? If so, what brand and model do you use and how well does your drive-of-choice work? Does anyone here buy empty USB enclosures and laptop drives to assemble their own cheap Time Machine backup drives? If so, what is your preferred scheme?
Thanks in advance!

Do I need to partition an external backup hard disk for use with more than one computer?
That's usually a good idea. See Time Machine - Frequently Asked Question #4.
Should I at least put folders on the hard disk for each backup to be separate, or won't that matter?
You can't. Time Machine automatically creates a Backups.backupdb folder at the top level of a directly-connected drive, and will only back up to it. For backups made over a network, it creates a sparse bundle disk image named for the Mac it's backing-up at the top level of the drive, and will only back up to that.
Since you have an iMac and a MacBook, you have a much better alternative than switching the drive from one Mac to the other: Connect the drive directly to the iMac and let the iMac back up to it directly. Then back the MacBook up to that same drive (preferably a separate partition) over your network. That way, both can back up hourly as long as they're awake (and the MacBook is in range of your network) automatically. See Time Machine - Frequently Asked Question #22 for setup instructions.

2x 10.5.2 xServe + raid backup solutions - Suggestions please!

Hello,
I'll give a brief overview of what I'm rolling out. *Limited budget* So keep that in mind
Basically I'm just looking for suggestions on backup solutions for this particular setup. I have been hearing mixed reviews of most backup solutions under 10.5.x... (In 10.4.x server I was relatively confident with Retrospect and had performed restores before).
--2 xServes, One web server, one for local services like mail, OD, AFP, Cal, etc. each has 2x 80gb drive (boot volume + mirror). Advanced server config.
--1x raid configured as raid6 with 4TB useable after formatting and parity. Data (user directory, mail store, calendar, web sites and database, etc) will be on the raid volumes, the 80 gb drives in xserves are only for OS and log files.
--All clients are using MacBook Pro's and most users have minimal data. Most data will be mail and quicktime videos (compressed for web, originals on mini dv tapes).
--MacBook Pro's already live, current server is SBS 2003 and it handles backups via Retrospect.
--Backups will have to be D2D, tape is not an option in this case. This means two external drives for backup (one on site and one off site, cycle on friday). Probably 2TB FW800 for each drive as entire raid isn't being backed up, some of it is scratch storage so 2 TB is plenty for now).
Naturally I want to use time machine but I am hearing of horror stories using time machine to backup advanced server in 10.5. Also seeing issues with cyrus (mail) and time machine (I will be running mail services). In addition, I don't think I could do any sort of cycle with the two external drives using time machine? The lack of configurability in time machine worries me. And finally, I don't know how time machine does with active database' (Ie: sql database for web server, I just don't know if time machine will cause problems when trying to back live database up). If someone has experience with time machine in a similar setup I'd love to hear your thoughts / suggestions.
Alternatively there is retrospect. We already own a license and I am familiar with administering it on 10.4.x. How reliable is it for backing up 10.5.2 clients and 10.5.2 server? Including active databses (Again the web server sql databases, etc? Kind of a pain restoring anything from retrospect (Especially entire server if / when it has to be done) but it was tried and true for me in 10.4.x server installations.
These MacBook pro's will also likely become mobile homes once all is said and done (But currently are not as the xServes are not installed yet). Time machine + mobile home directory seems like a lot of data being backed up that is probably redundant?
To top it all off, until new office is ready (All gigabit when that happens in ~1 year) network is as follows:
Servers have 100 mbit full duplex connection
Clients have 10mbit half duplex (This is where time machine really frightens me with hourly client backup).
Considering above, I can either:
A: Run proactive backup script from retrospect for all clients and then nightly backup for select raid volume contents + server boot volumes.
B: Not backup clients directly via retrospect and only backup contents of the raid volume (Which is where the mobile homes will be stored). Mobile home sync would be set to occur on login / logout only (Considering 10mbit client connections, I don't want active or user initiated sync heh).
Thoughts / suggestions? Thanks in advance, any suggestions are much appreciated. Hardware is set in stone but backup solution is not so most aspects of backup solution can be changed =)

First of all, thanks for your reply!
Well I should clarify in that I wasn't going to operate "network" homes and that they were just going to be the mobile homes with sync only occurring at login / logout. Even then, I think I'd run in to issues with the 10base-T for the client systems. The servers are on 100base-T full duplex. Currently All of the Windows systems do the same and logging in / out isn't too terrible but I couldn't imagine actually running the home directories off the server on 10base-T.
Do you still think mobile homes would be too much with just the login / logout sync? If so, I'll simply avoid this option until we get our new building and gigabit networking all around in the next year.
You're correct in that all clients will be running 10.5.2.
If I am not running mobile homes, I suppose the easiest way then is to in fact backup clients via time machine to the raid volume and then backup the entire raid volume (Hence all of our sites, compressed video files and databases to a large external drive (Maybe I'll get a couple 3 or 4 TB raid drives instead... lol). Naturaly I'd select the scratch disk directories and tell time machine to ignore them. Only issue there being that I may run in to space concerns like you say. If it becomes a huge problem and apple still hasn't made TM more configurable by then, I could use the time machine editor app or modify the intervals myself. I'd rather not and will only do this if it becomes an issue
From what I can gather, time machine is not making complete duplicates of an active database (MS Entourage in this case) and is only backing up the changes. I was worried about how it handled this and whether it would detect a change and just backup the entire database again (Which would be a nightmare if it did this for our web directories as they have active databases running).
Do you know of time machine will wreak havoc with active databases (Like the ones our websites use, a couple small sql databases and one larger one).
I think time machine would work well with the method you suggested. So I can just set it to backup all clients to the raid volume and then setup time machine to backup the raid volume to the external disk? For my off site... I suppose I could just bring in the second identical external drive every Friday and copy the time machine backup database from the on site backup drive on to it and then get it out of there each evening.
As for backing up the servers themselves, they will not be storing much of anything and most everything will be pointed to the raid volume (Hence the 80GB drives). Because of this, the data on the servers themselves will not change THAT much compared to the raid volume which will change drastically every day so full backups of the servers is fine. Perhaps just setting psyncX (assuming it works in 10.5) to backup the 80GB boot volume for each server would be best? I could just set psyncX to backup each server boot volume to the same external drive the raid volume is backing up to and then each friday just copy the data from the on site drive to the external, killing two birds with one stone. (Tape would make this all easier but it isn't gonna happen in this case sigh).
I worry about the cyrus / mail issues I'm reading about on servers running time machine though.

Any reason I shouldn't do it this way? RAID backup question

I'm using three 1TB drives torn out of Western Digital external hard drives (hard to find internal drives in Italy) as a RAID 0 for 3TB internal storage in the three extra internal bays. I'd like to mirror that, or something close to it, for a reasonable price. Is there any reason I shouldn't just buy three more external 1TB drives (around €110 for USB2 each) and combine them into a RAID 0 using Disk Utility? Since I'll be using it as a backup for my internal raid, speed isn't really an issue. I'd like to be able to just use Synchronize Pro or Super Duper to regularly schedule backups.
I'm asking because it seems like the cheapest alternative is 4TB RAID boxes like Jobo, Lacie or WD that run about €1000.
Any thoughts would be greatly appreciated...

Hi,
The only draw back that I can see with mounting three more hard disks internally in the Mac Pro is that you may need to remove the DVD, the Mac Pro will run warmer and of course it will be louder. You will need to decide if this is what you want.
I find that the SeriTek/5PM is a better solution.
http://firmtek.stores.yahoo.net/sata5pm2se2.html
http://www.amug.org/amug-web/html/amug/reviews/articles/firmtek/5pm/
The SeriTek/5PM is quiet, provides great HD cooling, and allows the user to easily turn off or remove hard disks that are not currently needed. This reduces energy usage, helps backup disks last longer, keeps the Mac Pro cool and quiet and provides virtually unlimited hard disk capability as hard disks can be hot swapped as needed. It will cost more for this configuration but it provides much more flexibility.
Have fun!

External RAID backup

Would it be possible to have two External Hard Disks and make them work as a RAID Mirror, for backup purposes?

If you have FW800, then look for a dual drive case with mirror RAID capability.
http://www.macsales.com/firewire has some.
but normally you want two drives on a bus with enough bandwidth to write to both at an acceptable performance, and interface.

RAID/Backup Setup General Help/Advice Needed

I've got a PowerMac G5 Dual 1.8 with an internal 80GB (all apps) as well as an internal 300GB SATA Seagate (all files), as well as an external 120GB firewire drive I'm using for backup now.
I'm looking to setup a more professional system for backup since my business is growing rapidly and I need a better system than "dragging and dropping" whenever I think about it, and burning millions of DVDs and hoping I've backed up everything.
My initial thought was to put a couple 300–500GB drives in my G5, put all apps/OS/files on one of those drives, and setup RAID to have the other drive mirror it (i have basic understanding of all this, but not 100% yet).
I'm now looking into the Buffalo Terrastation and other options. I'm not sure a networked backup is right for me. Overall I'm very overwhelmed and I'm trying to narrow this down.
I do mostly print and web design daily, and my print project files can be as large as 10GB per project. I just want a system where I can work daily, and pretty much have the same good speed of work as I always have, and not really have to think about backup too much.
I'm open to all suggestions and sincerely appreciate anyone who takes the time to respond.
Thanks!

RAID 1, like Alan says, immediately writes to another drive, you lose the benefit of time. It's really only good for mission critical uses where a hard drive failure would be devastating, like recording ET or something.
RAID 0 is a high performance option that splits the data path as it flows so writes and reads are greatly increased. But it offers no backup, and if one drive dies it takes all your data on all the RAID 0 drives with it.
There are other forms of RAID involving lots of drives which offer different levels of speed, and redundancy. The two I give above are those offered by Apple's Disk Utility. The others are probably better served by a dedicated hardware controller as not to over tax your processors.
If your heavy into large data storage, video, audio then you'll need to look at a RAID 5 or a RAID 1+0 and something like a Apple X-RAID and a PCI Fiber-channel card.
Do I leave the externals running all the time? Will they mount to the desktop as well?
Well with anything that auto-clones/backups the participating drives must be on and mounted. Unfortunately Apple doesn't offer a "per drive" sleep function, sleeping a boot drive affects performance.
However if your security conscious like I am and keep your other drives disconnected, then you'll have to plug them in and use the software manually.
What sort of backup regiment you use is up to you, I keep most all my data on my RAID 0 as boot, clone occasionally to two other drives and keep them disconnected for maximum security.
You might want to do some sort of combination of both, file drive auto-backed up nightly and clone your boot drive once a week manually.

Seeking RAID/Backup advice...?

I'm looking for a solution that enables me to take home a backup of the 'work drive' from a 6-Mac design studio. This is not my area of expertise, so I'd appreciate any 'expert' advicve on this subject.
Current set-up:
PowerMac G4 'server' machine with a second HD which serves as our 'work drive' on our LAN. An external Maxtor HD is set-up to duplicate the work drive overnight, but that gives us no security againsy fire ot theft..!
I understand that a RAID system could be configured to give us insurance against drive failure, but is there an option to use a hot-swappable/removeable drive to mirror the data which can then be taken home at the end of each day?
Thanks in advance.

You could do this with an Xserve RAID with mirrored disks (although once your 'Work' drive grew beyond the capacity of a single disk, it would get slightly more complicated), but it would be an expensive solution, and is not really what the units were designed for.
You could save yourself a lot of cash by just getting two firewire disks, and setting up two Retrospect 'Backup Server' scripts that would automatically run nightly, to whichever drive happens to be attached.

Hey All,
Does anyone recommend any backup software for RAIDs other than rsync in the terminal?
I know we have gone over this topic multiple times, but I just wanted see if there is anything new for Snow Leopard Server. Rsync and Lingon are just becoming too much of a pain in the you know what lately!

Although I would steer you clear of Restrospect - I think most of the veteran users of this site might agree? Having said that there are some who have no problems with it. Who knows for you it might be the 'ideal' solution? If your data is precious to you do you want to risk it? For me it's too unreliable when it comes to restore. Additionally there have problems with it since Roxio took it over - Scripts disappearing and media being lost etc.
I've not tried all of the ones listed and no doubt there may well be others. The ones I have tried I've had no problems with - NetVault and BRU. In some environments and depending on the circumstances I've had no problems with TimeMachine.

Backup scheme for two destinations?

Hi all,I'm helping at a small school and am working on implementing a backup solution here. What we have is two practically identical Dells (T110 II) as backup servers, with ~11 TB of usable space each. A "full" campus backup is estimated at around 6 TB, so the theory is to do a full backup each week, alternating between the two servers as a destination. In other words, there is a full backup made somewhere every week, but each backup server gets a new full backup every other week.Full-A I1 I2 I3 I4 I5 --------------------------- Full-A I1 I2 I3 I4 I5
--------------------------- Full-B I1 I2 I3 I4 I5 --------------------------- We are planning on nightly incrementals, but I'm not sure if those too should alternate weeks (as hopefully illustrated above), or continue straight through. If the latter, network congestion may possibly be a...

Backup scheme

my 3 yr old 17" MBP 200gig HD if full. I plan to get (2) 750gig WD Scorpio drives from Newegg.
1. I need to copy my current internal drive to both new drives. I have a adapter to put the new naked drives in. What would be the best method to copy all data. Carbon Copy Cloner or something else, maybe TimeMachine. I need to keep the OS intact and functional.
2. I eventually need to put in the new 750gig drive and make backups to the other 750gig. I use TimeMachine now. I just want the backup drive to be able to be inserted in the MBP should drive 1 die one day.
thanks for any good ideas.

RAID Mirror using partitions

Hi all,
I've got 3 Samsung Spinpoint F1 1TB drives in my MacPro. One is dedicated entirely to Time Machine backup. The other two I would like to split into two equal partitions and then setup RAID (mirror) arrays using Disk Utility like this:
RAID 1 = Disk1,Partition1 + Disk2,Parition1
RAID 2 = Disk1,Partiton2 + Disk2,Partition2
The first RAID gets created without a hitch... but then the second RAID fails and won't create/mount.
Is this even possible on OS X 10.5.8? If so... I'd really appreciate any help, as it seems like this SHOULD work, but it just WON'T.
Thanks!

Kappy,
Thanks for the additional info. I've got scads of backup going on... I regularly (like, hourly) use Chronosync to synchronize all of my important files between my Mac Pro and my MacBook Pro so there's one... I also user SuperDuper to maintain bootable backups on separate external drives for both computers... AND I've got two separate external backups of my important client files (backed up into a secure sparse disk image on two different external drives).
So... I came up with the scheme of having the RAID on the boot disk while I was trying to re-allocate some new drives from my MacPro and external drive enclosures. I realized that the original, 320GB drive that came in the MacPro was a dog and was significantly hampering performance (the MacBook Pro is actually faster at performing disk-related tasks!). So... I had a Samsung SpinPoint F1 1TB drive that I was planning to put into an OWC FW800/400/USB2.0/eSATA drive enclosure to use as part of my external backup scheme that I thought would serve me better as my boot disk. But, since I've only got about 200GB of the 320GB filled on the current drive, I figured I had a lot of space on the 1TB drive that would go to waste.
Hence... I hatched the "brilliant scheme" of partitioning 2 of the 1TB drives in the MacPro equally and then creating a RAID... figuring that would provide at least some reason for having the overly-large drive for my boot disk. RAID mirroring would give me a level of protection against disk failure and would reduce the "clutter" of having too many drives/partitions showing up on the desktop and in Finder.
But... all of your comments are excellent ones. So, I'm sticking with the interim solution I posted earlier. No RAID on the boot disk partition, but a RAID on the important client files partition to provide drive-failure protection above-and-beyond my existing backup schemes.
Thanks, again, for all of your input.
Regards,

Raid Admin 1.5 - Recognize Array button not active

Hi all,
just updated to RaidAdmin 1.5, updated firmware on both controllers to 1.5 version.
I have 6 disks on which should be my lost array. Suddenly 'Recognize Array' button in utilities is not active.
Any idea?
Leos.

ok. The whole story:
Few month ago, I had RAID 3 schema on 6 disks. I did firmware update on my XRaid. This update WAS SUCCESSFUL. After XRaid restart, I lost my array. I didn't have backup. After unsuccessful local Apple support, I tried 3rd party companies to reascue my data. Noone helped me. I managed help from Apple in US, I sent my disks to them (quite expencive, I am from Czech Republic.). They recovered raid set on my disks to RAID 3 schema on 5 disks only - don't understand this. So I called them back a and I sent disks again, with detailed desription how it must be. Thay sayed OK and sent me back 6 disks, with no raid set schema - 6 unassigned to any array. And as a bonus, one of them was failed. So, now I have 6 disks, Apple claims, that raid schema is on disks (but i cannot see it on my raid - I realy tried everything - swapping possitions, controllers, cables .....). So when Raid Admin 1.5 brings this new function - recognize array, I started thinkink, that I have one more chance to recover my data back. But situation is as I described in first topic....
