Splitting backup between two EHDs?

I hope to buy a new iMac this week. The HD is 640GB, if I remember right. My EHD for backups is only 300 GB, which is enough for right now, but I'm not sure what to do when I get more than 300 GB of data on my computer!
Would it be better just to buy a bigger EHD? Or can I use Time Machine to split my backups between two smaller EHDs? (For example, my jpg-containing folders would always back up to one EHD, while my png-containing folders would always back up to the other.)
I'd really rather just buy a second 300 GB EHD, if possible, because then I can start using it right away for selective duplicate backups of my really important stuff. Just not sure how that will work when I get more than 300GB of data on my computer.
Thanks!

Time Machine can not work with more than one backup drive.
The rule of thumb for a TM drive is to size it to twice the size of the drive you want to back up. TM is not just a simple backup program. One very important reason to use TM is to be able to restore deleted or older versions of files. This requires more storage than just the size of the boot drive.
External hard drives are usually fairly easy to upgrade by purchasing a larger drive and installing it into the external case.
You can also choose to exempt certain large collections of data from the TM backup, like music, video, photos, or folders and then use a program like SuperDuper to run a schedule to back those folders up to a different drive on a regular basis.
You could also use your exising drive as a bootable backup with your OS and most important files copied on a regular basis with a program like SuperDuper! so that you have a bootable backup to test with, or to continue work with in the event your main drive fails.

Is it possible to set up a backup between two external drives

Is it possible to set up a backup between two external drives?
i use time machine to back up my imac onto an external 2T.
i also have two external 3T drives. i am looking for redundancy of data, tried software RAID and it failed. i also see some limitations with RAID that a backup would avoid.
thanks for sharing your expertise.
be well,
tony

so thanks to all of you, particularly rkaufmann87 i have decided to stop the plan of setting up a software RAID set. instead i have downloaded ccc and am in the process of setting up the secone 3t external drive as a clone. i will use time machine to back up the internal hard drive only and if possible see if i can clone that as well onto one of the 3t's.
this gives me the peace of mind i sounght and avoids the problem of total corruption that exists with the raid solution i was exploring.
thank you all for making this an enjoyable and informative experience. what a powerful community.
be well

Sharing a Time Machine backup between two Macs

Hi
So I was running my music production software on a first gen Mac Mini. I would store all of my project files on an external drive and backup that external drive to a second external drive using Time Machine. I had Time Machine set so that it excluded everything on the Mac Mini except my original external drive.
Now I've stepped up to the latest and the greatest Macbook Pro 15 inch. I'm running the same music production software on it and loading up all my files from the same external drive. When I go to back it up with Time Machine, it wants to start a separate backup for the Macbook Pro, even though it is only backing up the same stuff from the Mac Mini. The thing is that there aren't any system specific files being backed up, just my project files. For the life of me I can't get it to continue the original backup. I plan on using both Macs for music production and plan on using the same drive for both. I would like to back up every time I finish a session on either computer.
Is there anyway I can get Time Machine on each computer just continue one backup??
I know I can access the backup from each computer by "Browsing Other Time Machine Disks", but I want to backup, not restore.
If not, is there any other software you can recommend? Although I would hate to lose the backups that I already do have...
Thanks!
jg

That's probably a good option for you. It's not easy to keep a 3 way sync.
If you really want to keep certain files synced on your Mac Mini, you might want to look at ChronoSync. It appears it's a good backup-sync program. Don't know if will keep synced between the 2 computers and external drive without a little manuel effort, but would be easy to sync at least 2 devices, such as MacBook to Mac Mini, or MacBook to external.
If you don't need to keep synced files, then best option is to do a full TM backup of both computers. Since you have 2 externals, use one for each. You can still use TM to access files if you need, and if you have a hard drive failure, it's an easy replace drive and restore the whole computer from TM.
And don't overlook the option of File Sharing between the 2 computers to access each others files or a shared folder. That's a real easy way just to copy a few files when you need them.
Anyway, Good Luck and Happy Holidays

How to do a locked split-screen between two different video tracks

I'm creating two time-lapse videos and then I'm planning to to play them side-by-side in one sequence.
The way I was planning to do this was to scoot one video track over using the "center" tool in the motion panel, and then crop it on its right-hand edge to reveal the other video track beneath.
The problem with doing this however is that, as the camera gets bumped or moved slightly as the months go on, and I then have to cut and reposition the "center" location for the clip, I have to then adjust the amount of crop on that video clip since I've moved its position. This means the center split-screen location keeps changing as I move the video around.
Is there a way where I can just lock the split screen smack in the middle of the frame as I tinker with each side of the frame (video track) independently? I tried adding a split-screen transition in the very beginning to the top track, but I can't make cuts on a transition to then adjust the motion attributes.
Any ideas on how to simplify this process would really be appreciated. Originally, I thought there was no easier way to do this, but I was so blown away by all the answers to my motion effects question today (and all the things I never knew about FCP) that I thought it wouldn't hurt to see if someone out there had one more ace up their sleeve. If not, I'll assume this is one of those things that can't be simplified anymore than what I'm doing.
Thanks again guys,
Chris

Though David's Motion Tracking suggestion would eliminate alot of later finagling, you could try something similar to Reink's, without using Photoshop.
Try this...
1. In a seperate timeline, drop a Matte/Color Solid into the new timeline (using dropdown at bottom right of Viewer window).
2. Dbl-click the color solid, click on Controls tab and set Parameters as H/0, S/0, B/100. Then click the Motion tab/Crop Right-50.
3. Click the Viewer's Video tab and go to Export/QTConversion/Still Image (png) and name it something like WhiteMatte_CropR50.
4. Import that into your project.
5. Now with your two timelapse clips on V1 and V2 with in/out points at head/tails and both tracks highlighted...'Nest' the sequence...Main Menu/Sequence/Nest Item(s).
6. Next, with the nested sequence active (single clip will look light purple)...option-double click on it and and drop an Image Mask Filter on it, then drag the WhiteMatte.png clip into the 'image well' (little box that has a question mark in it). Keep the channel on Luminance.
7. Now, if you dbl-click the nest, it will open it's host sequence, that you can do your 'Motion Tab/Centering' on, without affecting the 50% split down the middle.
May seem like alot of work, but it's not really.
K
p.s...there are probably other ways to do this as well.

Split library between two drives

I'm sure this has been talked about but I couldn't find it. I have all my photos stored in the Aperture library. The Aperture library has out grown my 750GB drive. I want to add a seconded drive and have the library continue on that. How can I tell Aperture to continue on the seconded drive?
Thanks

Ian Wood wrote:
The images are always visible in Aperture whether they are referenced or managed. Basically, as long as the master files are online (the drive they are stored on is powered up and mounted) there is no practical difference inside Aperture between referenced and managed Masters.
I suggest you have a look through http://www.bagelturf.com/aparticles/ref/index.html for more info and pros/cons on referenced Masters.
Except for being able to back them up to an Aperture Vault. You'll need to backup your referenced files manually.
You didn't mention what kind of RAID you have. As long as you're backing up your Library, why not a larger concatenated RAID?

Backup between two locations

We have 2 offices. Instead of using cloud space to have an offsite backup, I am thinking of putting a Mac Mini in each office and backing up the other offices files every other night. We both have fiber optic internet service at 10mbps up and down. I was planning to VPN in to each server and then use Super Duper or something else. Time Machine would be great if it will work. I could run Lion server or Snow leopard server.
Does anyone see a problem with this setup? Any bottlenecks? Suggestions?
Thanks,
Rich

I'll chime in here because I do the exact same thing now and it works beautifully.
We have an Xserve at one end and a Mac Mini at the other. Every night the Xserve backs up to external storage attached to the Mini at the remote location. The connection is made through a Point2Point circuit (fiber).
I use Carbon Copy Cloner (http://bombich.com). I HIGHLY recommend this app. You can schedule your backup tasks to run at specific times or at a regular interval, and it sends you email notifications so you don't have to comb log files to make sure your backup ran.
There are no bottlenecks or problems that I've encountered. It backs up your data thru an SSH tunnel. Part of the setup process involves the app generating public and private keys, and then you install the public key on your remote machine to falicitate the SSH connection.
This is pretty much a flawless backup strategy. I've never had a problem with it.

How can I split a backup on two hard drives with Time Machine ?

Back-up of my Imac with time machine is 1,3 TB. I have two 1 TB external hard drives but even if I had both as available in Time machine, it seems it doesn't allow to split the backup between the two hard drives. Any way to resolve this without buying another hard drive with more space?
Thanks in advance

You cannot directly split a backup. Your only option would be to open the TimeMachine preferences from System Prefs. and add things to the exclusion list for one of the backups. Then, when you go to do the other backup you would reverse the process and add everything else to the exclusion list and remove the things you had on there in the first place.
Seems fairly intensive though when you could just go and buy a 2 or 3TB external drive and do it all in one...Black Friday is coming up

How do I set Time Machine to alternate between two attached external drives (so that if one fails I will have a separate backup to use)?

Hi Everyone.
Thanks in advance for your help.
Right off the bat let me say I am using Mavericks 10.9.1 on a 2011 Macbook Pro and using all Lacie external hard drives.
I am trying to get Time Machine to alternate between two attached external hard drives, trying to be safe in case one of the backup drives itself fails.
I have both drives set in Time Machine.
From what I gather Time Machine should by default alternate between drives when backing up (I would assume it does one big initial backup on each then subsequent backups are just changes).
But this is not how it seems to be working and I cannot find a straight answer despite much Googling and Foruming
Unfortunately it seems to only be backing up to "External Hard Drive 1".
There have been 4 backups since I set it up, all on "External Hard Drive 1", even though "External Hard Drive 2" is also attached and set in Time Machine.
I manually clicked "Back Up Now" and it started to work on "External Hard Drive 2" (like I want it to) for a minute but it appears to have stopped and gone back to backing up to "External Hard Drive 1".
Am I missing something? Does Time Machine only move on to another disk when the first one runs out of space? Do I have to turn one off in order to force it to back up to the other drive (that would be less convenient of course)?
I am hoping that I am missing something and that it will just alternate between the two. Otherwise it is not the most comforting and thorough backup system as I had hoped when I purchased the additional external hard drive.
I have a 1TB drive and a 500gig partition on another drive, both dedicated to backups (my Macbook HD is 475gig). It will take awhile for each to fill up and who knows what could happen during that time. Having Time Machine alternate between hard drives would be a nice small bit of security if the worst happened.
I realize that there are tons of other options for backing up but I just want to use Time Machine if I can.
Again thank you for your help!

You cannot use Time Machine in that way. I'm not sure where you heard that Time Machine alternates between drives automatically. What you can do is create a mirrored RAID array for the backup. This automatically duplicates whatever is on one drive onto the other drive.
Both drives must be the same size, and prefereably, exactly the same make and model. RAIDs can be configured using OS X's Disk Utility.
RAID Basics
For basic definitions and discussion of what a RAID is and the different types of RAIDs see RAIDs. Additional discussions plus advantages and disadvantages of RAIDs and different RAID arrays see:

Hardware or Software RAID?
RAID Hardware Vs RAID Software - What is your best option?
RAID is a method of combining multiple disk drives into a single entity in order to improve the overall performance and reliability of your system. The different options for combining the disks are referred to as RAID levels. There are several different levels of RAID available depending on the needs of your system. One of the options available to you is whether you should use a Hardware RAID solution or a Software RAID solution.
RAID Hardware is always a disk controller to which you can cable up the disk drives. RAID Software is a set of kernel modules coupled together with management utilities that implement RAID in Software and require no additional hardware.
Pros and cons
Software RAID is more flexible than Hardware RAID. Software RAID is also considerably less expensive. On the other hand, a Software RAID system requires more CPU cycles and power to run well than a comparable Hardware RAID System. Also, because Software RAID operates on a partition by partition basis where a number of individual disk partitions are grouped together as opposed to Hardware RAID systems which generally group together entire disk drives, Software RAID tends be slightly more complicated to run. This is because it has more available configurations and options. An added benefit to the slightly more expensive Hardware RAID solution is that many Hardware RAID systems incorporate features that are specialized for optimizing the performance of your system.
For more detailed information on the differences between Software RAID and Hardware RAID you may want to read: Hardware RAID vs. Software RAID: Which Implementation is Best for my Application?

Payment Method split between two types (cash & credit)

I am looking for a way of splitting a customers payment between two methods in one sales order. For example, a customer purchases an item valued at $100. He wants to pay with $50 cash and put $50 on a credit card. Currently the payment method resides in the header of the sales order and only one can be selected. Is it possible to create a multi selection option, or to apply the payment method at the line item level?

Technically it should be possible to maintain a different payment term on the line item level in the sales documents. The field is stored in VBKD table and is also available at the line item level (although it's grayed out).
Such items would be split into 2 invoices though because it's not possible to have one invoice with two different payment terms.
Also if the payment method does not change the payment due date and other condition, then I wouldn't really bother at all. It's possible to post 2 partial payments against one invoice in FI, so why should SD side be even concerned about the methods? Unless, of course, there's something you're not telling...

Split gift certificate between two accounts?

I received a gift certificate for 50 songs on itunes. Can I split the gift cert between two different accounts ie half for me and other half for husband?

You can't. Once redeemed into one account, the whole balance is put there and can only be removed by spending it from that account or asking Apple to clear it; the balance can't be used to gift content or buy gift cards or certificates.

Can I put my library on an external hard drive and use it between two computers?

Can I put my library on an external hard drive and use it between two computers? I have two MBP; I will refer to one as computer A and to the other as computer B. I would like to be able to plug in my external hard drive, boot up iTunes, and if there were any changes made to the library previous to its last time accessed on this compluter, they show up on that computer, regardless of being imported on the other.
A hypothetical example: I import three albums called 1, 2, and 3 on computer A over a week or so. I take the external hard drive and plug it into computer B. The entire library which was visible on A, is visible on B, including albums 1, 2, and 3.
Is this possible? If so, what files need to be copied onto the external? I'm trying some different combinations, trial and error basically. Hopefully someone knows and can answer before I mess up my library. I also want to do this to free up space on my computer. All importing will be done from disc.

iTunes/Preferences/Advanced : point your iTunes to the new location of the Library.
Set "Share on local network" in the Sharing tab, and you or everyone on the local network can play your music.
You make a backup first of the Library.
Move the follwing to the new location:
/Users/your username/Music/iTunes/iTunes Music
have fun.

OBIEE 11G - Issue passing parameters between two reports

Hi folks,
I am struggling to pass parameters between two reports in OBIEE 11G.
My first report contains the following columns: Rolling Year Type (VCHAR), Year(VCHAR), Month(VCHAR), Cost(Double).
My second report contains the following columns: Rolling Year Type(VCHAR), Year(VCHAR), Month(VCHAR), Category(VCHAR), Cost(Double).
My requirement is to pass the Rolling Year Type, Year and Month values from report 1 to report 2.
On the Month column properties of report 1, I have created an Action Link called 'Drill to Category'. I have clicked on 'Navigate to BI Content' and selected Report 2.
Then on Report 2, I have included three filters: Rolling Year Type is prompted, Year is prompted, Month is promted.
When I run the report I always get the following error:
The specified criteria didn't result in any data. This is often caused by applying filters and/or selections that are too restrictive or that contain incorrect values. Please check your Analysis Filters and try again. The filters currently being applied are shown below.
When I check the cursor cache, the filter values are correct. Does anybody have any idea why Report 2 does not display?
When I remove the Month filter, the report works correctly.
I have since changed the third filter to be Month No and although Report 2 does display, it does not pick up the filter on the Month No.
I initially thought this may have been a caching issue and so I have disabled BI Server Cache but this does not fix my problem.
This was never an issue on OBIEE 10G as I found it very easy to navigate between two requests.
Has anyone else experienced problems with passing parameters between two request in 11G?
Any help appreciated.
Thanks
Gavin

Hi,
I once tried this kind of requirement(with dashboard prompts though) and hit at similar issue. I later found out that the problem is with the space in the parameter values. Can you please let me know, if the same is the case with you?
Suppose the parameter passed is "Jan 2010", but the report on the destination takes the value as "Jan" & "2010". Yes, it kind of split the parameter value to two based on space. I think we can notice the filters the destination report got, by enabling filter view.
In this case, since you pass only value at a time, could you try placing the parameter value anyway in double quotes? I think the Server then will understand it as one value.
Thank you,
Dhar

Authentication needed after doing trust between two different domains.

Hi There,
I have a problem when i did the trust relationship between two different domains in two different forests ,,in the trust relationship steps all working two ways trust,with external trust,stub zone created on both domains and they are validated in both sides
,,my problem is with the objects it can't be retrieved from side and it can be from the other side . For instance :
NY domain can get the users and computers of 2012DC1
but 2012DC1 can't get the users and computers of NY
Date and time are the same,i am always getting this error
The session setup from computer '2012DC1' failed because the security database does not contain a trust account 'test.com.' referenced by the specified computer.
USER ACTION
If this is the first occurrence of this event for the specified computer and account, this may be a transient issue that doesn't require any action at this time. If this is a Read-Only Domain Controller and 'test.com.' is a legitimate machine account
for the computer '2012DC1' then '2012DC1' should be marked cacheable for this location if appropriate or otherwise ensure connectivity to a domain controller capable of servicing the request (for example a writable domain controller). Otherwise,
the following steps may be taken to resolve this problem:
If 'test.com.' is a legitimate machine account for the computer '2012DC1', then '2012DC1' should be rejoined to the domain.
If 'test.com.' is a legitimate interdomain trust account, then the trust should be recreated.
Otherwise, assuming that 'test.com.' is not a legitimate account, the following action should be taken on '2012DC1':
If '2012DC1' is a Domain Controller, then the trust associated with 'test.com.' should be deleted.
If '2012DC1' is not a Domain Controller, it should be disjoined from the domain.
Can you please help me in this error.
Thank You in advance.

Hello,
"The session setup from computer '2012DC1' failed because the security database does not contain a trust account 'test.com.' referenced by the specified computer. "
This belongs to the machine 2012Dc1 in test.com and not to the other domain from your trust. Seems for me that you mix the trust with the problems of the machine 2012DC1 in test.com.
In this error message 2012DC1 has lost the trust to its OWN domain and therefore you have to find the reason. How exactly was this machine installed?
Or was there a restore on that machine from not supported type of backup like image/clone/snapshot?
