Clone and TM on same disk

My TM and a bootable clone are on the same disk. If I boot to the clone to have a look around, how do I prevent MobileMe and TM from backing up the clone. I cancelled MobileMe, but TM has not tried to backup yet. Will TM try to backup the clone? If so, how do I prevent MobileMe and TM from backing up the clone? If I restore a file from TM while booted to the clone, where will it go? Are there any other things I should be aware of with this setup?

to prevent TM from backing up the clone add the clone to TM exclusion list in TM system preferences->options.

I don't understand what you mean by mobileme backing up the clone. do you mean Backup.app that comes with mobileme?
If I restore a file from TM while booted to the clone, where will it go?
as i said, exclude the clone from TM. if you restore something from TM while booted from the clone it will go exactly to the drive it was backed up from.
Are there any other things I should be aware of with this setup?
this depends on how your TM and clone are set up. are they on the same partition or on different partitions?

Acurrate process to clone and transfer all the disk to another tiger computer....

Please guys would be kind enough to show me an easy and acurrate process which incude process to clone AND transfer all the disk from my powerbook G4 (10,4,11) to a macbook (2,1)also tiger computer 10,4,11....
(Carbon copy cloner or easier again you can think of....)
TY

Unfortunately, this can't be done. Although you are using the same OS version (Tiger) the PowerPC version (your G4) is not compatible with the Intel version (your MacBook). There was never a Universal Binary (version compatible with both platforms) for Tiger. Apple only produced separate PPC and Intel versions. If you were to clone your PPC version over to your Mac, it simply wouldn't run at all.
You can use Migration Assistant which will move over all of your files and settings. However, none of the applications you have installed will run as they are all PPC. You would need to see if there are more current versions that are Universal Binaries.
I wouldn't really recommend migrating at all between platforms. I would start with a fresh install of a more current OS on your MacBook and then reinstall your apps one by one. You can manually move over any personal files (pictures, music, office-type documents) by copying them over to a flash drive or by putting your G4 in Target Disk Mode.

Carbon Clone and Time Machine: developing a backup plan

Howdy all!
This is a second post that sort of flows on from another I have written today
https://discussions.apple.com/thread/4649740
I initally put them all together, but they were too rambling and disconnected, so it seemed better to seperate them. The question I have here is how best to organise my backup plan? I have a few ideas, but, basically, want to make sure I get the whole setup right the first time and would appreciate any advice from others that have been down the path before. As I am still waiting for some parts to arrive in the mail, I have a little time to think about how to go about setting up my Mac.
Basically the setup is:
Mac Mini 2012, boot drive is a Samsung 256GB 830 series SSD, seconday drive for data is a 1TB mechanical disk. I plan on having all my data on the seconday mechanical disk (photos, movies, music etc) and only the OS and Applications on the SSD. To this end, I understand I only have to move /Users to the mechanical disk to achieve this. I then also have 2x 2TB Western Digital MyBook Essential USB 3 disks for Time Machine backups. I plan on rotating them on a weekly basis (storing the disk not in use in a safe or offsite), and then, depending on costs a cloud backup service for some data (music, photos etc) which I might want to access when im not at home.
So I have been thinking for a few days now on the benefit of having a Carbon Clone bootable recovery drive. The thinking goes along these lines. As my data is on a seperate drive, and is backed up to Time Machine, in the event of an OS disk failure, I can replace the disk and then point /Users to the new drive, and I can be up and running once I have reinstalled the apps i need. Now, I understand the idea of the Carbon Clone backup is such that it speeds up the time to rebuild the OS disk, but I have to question, how useful is this in reality?
Consider, I can sit down now and write down all the apps I have needed in the past, install Mac OS, set it up (possibly with a generic admin password), install the apps I need from the App store and DVDs etc and then take a Carbon Clone at this point before any setup of Apps are done. If the apps configuration is backed up in the Time Machine backup (i.e.: the config files exist under /Users) then this is almost workable - in a recovery situation, the CC clone is used to rebuild the OS drive, the config files are pulled from the TM backups, and we're back up and running. Where this fails, is if I have installed (or removed) apps since the CC clone was made. At this point then, is it best to (a) make a new clone when a new app is added/removed or (b) make a note of apps added/removed, which will then have to be reinstalled if a recovery is required. I tend to think the (b) method is best here, as it preserves the integrity of the clone. If the machine has been compromised (malware etc) then remaking the clone, causes the clone to be compromised and hence the reinstalled machine as well. Though this method could be a pain if the machine state has changed somewhat over time. Also, it means that the reinstalled system will be missing updates etc which could be time consuming to apply anyway, so the usefulness of a clone is slightly reduced anyway.
Does anyone have any thoughts on this? Some days I think having a clone will be useful esp. as most of my software was delivered on CD (Adobe Creative Suite, Office) or are large install bases (XCode), but other days I think, "its not a mission critical machine", i can survive a day without it while I rebuild the install, and so I dont achieve much by having a clone which is likely out-of-date by the time I go to use it.
Also, in this backup plan, is it best to rely on TM for things like email backup or a dedicated mail backup utility? can a Carbon Clone exist on the same disk as Time Machine uses, or do I need to invest in a new disk or two for the CC clones?
As I say, I want to make sure I have this machine setup right from the start, and would really appreciate any pointers, tips or advice.

There is one big advantage of a clone. You can immediately reboot
to it and continue working and deal with the regular boot drive faiure,
what ever it may be, later. Especially since all your data and such
is on another drive. If you use your computer for work and time
critical projects, this is a major plus!
In the case of a hard drive failure/replacement, copying the clone
to the drive is the fastest way to get the system and all your settings
back.
Time Machine and incremental backups have a place as well. It is best
suited for "incremental" problems. Examples are installing an upgrade to
software that doesn't work or just don't plain like. With Time Machine it
is easy to just restore back to the point before the install.
Something else I do is backup current project files to USB memory sticks.
If you are using your computer for business, you can never have too many
backups. Coralllary 456 of Murphy's Law is the "number of backups that
you need will be one more than what you have!"

I loaded in Lion - but my time capsule will not back up. I get an message: couldn't complete backup due to a network prolem. Also it says "make sure your computer and back up disk are on the same network, and that the backup disk is turned on.

I installed Lion on my Mac Pro laptop. Regarding Time Capsul - I get a messaage as follows: couldn't complete backup due to a network problem. Make sure your computer and back up disk are on the same network and that the backup disk is turned on. Then try again to back up. I have time capsul turned on. bill

I have exactly same problem with my MBP and MBA, after upgrading to Lion. I've tried to fix this issue while cheking key chain issues and network setup, even formating hdd and time capsule firmware upgrade (ver. 7.6.1.). Nothing can help. It is very annoying.

Creating a Master virtual hard disk and using the same for all other VM's

Hi,
We would like to create a master virtual hard disk and use the same for all other VM's. Can we do that ?
my requirements :
1) create 10 VM's
2) first create a master virtual hard disk with win OS and use the same to create the 10 VM's.
3) After creating the VM's change the HDD size.
              -- if i have created master virtual disk with 500GB , and use the same for creating a virtual machine. can we change the HDD size to 1TB ?
After creating the VM's ,i will change the system names and activate the windows accordingly.
Will there be any implications ,if we can/will do like this.
Thanks.

When I check my boot SSD drive using Disk Utility under Mavericks, I often get "Incorrect number of extended attributes" errors. But if I boot off an external drive and check the same SSD, no errors are reported. Is this a bug in Mavericks?

When I check my boot SSD drive using Disk Utility under Mavericks, I often get "Incorrect number of extended attributes" errors. But if I boot off an external drive and check the same SSD, no errors are reported.
This happens not just with the SSD in my Mac Mini, but with another SSD in my MacBook (both now running Mavericks). So far as I know, all of the kit I am using is in good order (despite the file corruption reports). So I am beginning to wonder if it could be due to a bug in Mavericks? Both SSD drives have been formatted to MacOS Extended (journaled) format. Should I have used a different format, I wonder?
Has anyone else encountered this issue?
Does anyone have a solution?
Or an explanation that might help my investigation of the issue?
Thanks guys,

I understand that the Corsair Force 3 is not one of the SSD drives that are supported on Apple Macs.
I did try downloading and using Trim Enabler, but the error message came up both when it was off and when it was on.
I understand that not everyone thinks Trim Enabler is a good program, though there is a new version out now, so I may give it another try.

Is it possible to run two different versions of Apple operating system (for ex. 10.6.8 and 10.9) on a MacBook Pro, either on the same disk or from an external hard disk? If so, where would I find the details?

If you want to add a second partition to the internal drive (in Disk Utility, select the drive, then open the partition tab and just click the + button), you should first be sure that you will have enough room to accommodate whatever the second volume will be. I am currently doing this for Snow and Mountain Lion.
To get to whatever volume is not the startup disk, restart and hold down option/alt at the chime, which will bring up a selection of the two volumes. Use the left or right arrow keys to select it and then hit enter/return.

Is it possible to import photos from a disk and retain the same order?

Is i possible to import photos from a disk and retain the same order they appear on the disk? When I import them, the come out in random order.

When first imported the photos will be sorted in the Event chronologically. On the disk they well be sorted by the Finder and that's usually alphanumerically by file name. So select the photos in the event and type Commnad+N. That will create a new album at the left with the photos in it. Then go to the View ➙ Sort Photo menu and select "By Title". That should give you the same order as you view the photos on the disk via the Finder.

Rman duplication of database to the same server and same disk group

Hi,
We have multiple databases - rmsprd1 and oidprd1 on asm disk groups - ASMDG_DAT01 and ASMDG_FRA01 on a server.
Both these databases are single instance asm based databases.
I am trying to do a rman duplication from rmsprd1 to rmsprd2 in the same server. I intend to use the same asm disk groups - ASMDG_DAT01 and ASMDG_FRA01.
Is this possible ?
Currently I have the following structure
+ASMDG_DAT01/RMSPRD1/DATAFILE
+ASMDG_DAT01/RMSPRD1/CHANGETRACKING/
+ASMDG_DAT01/RMSPRD1/CONTROLFILE/
+ASMDG_DAT01/RMSPRD1/DATAFILE/
+ASMDG_DAT01/RMSPRD1/ONLINELOG/
+ASMDG_DAT01/RMSPRD1/PARAMETERFILE/
+ASMDG_DAT01/RMSPRD1/TEMPFILE/
+ASMDG_FRA01/RMSPRD1/AUTOBACKUP/
+ASMDG_FRA01/RMSPRD1/BACKUPSET/
+ASMDG_FRA01/RMSPRD1/CONTROLFILE/
+ASMDG_FRA01/RMSPRD1/DATAFILE/
+ASMDG_FRA01/RMSPRD1/ONLINELOG/
Will I be able to create something like
+ASMDG_DAT01/RMSPRD2/DATAFILE
+ASMDG_DAT01/RMSPRD2/CHANGETRACKING/
+ASMDG_DAT01/RMSPRD2/CONTROLFILE/
+ASMDG_DAT01/RMSPRD2/DATAFILE/
+ASMDG_DAT01/RMSPRD2/ONLINELOG/
+ASMDG_DAT01/RMSPRD2/PARAMETERFILE/
+ASMDG_DAT01/RMSPRD2/TEMPFILE/
+ASMDG_FRA01/RMSPRD2/AUTOBACKUP/
+ASMDG_FRA01/RMSPRD2/BACKUPSET/
+ASMDG_FRA01/RMSPRD2/CONTROLFILE/
+ASMDG_FRA01/RMSPRD2/DATAFILE/
+ASMDG_FRA01/RMSPRD2/ONLINELOG/
I know that I can create a different asm disk group for the rman duplication but this is proving to be a hassle.
Thanks

Hi,
I have found the answer working with Oracle via a service request. Admittedly there was no direct oracle documentation for doing this and hence documenting the steps here.
No legalities, formalities involved please.
Here are the steps - rmsprd1 is the source, rmsprd2 is the target, +ASM is the asm instance supporting both rmsprd1 and rmsprd2. The intention is to put both the source and destination in the same server. The backupset backup in location /dbaadm/sandeep_rman_refresh will be used for the duplication.
1) Take rman backupset backup of the source database - rmsprd1
rman_take_backup.ksh ( Take backup of source - rmsprd1 using rman ). The contents of the rman_take_backup.sh script are given below :
rm /dbaadm/sandeep_rman_refresh/*
export NLS_DATE_FORMAT='YYYY-MM-DD:HH24:MI:SS'
rman target / <<EOF
run
allocate channel d1 device type disk format '/dbaadm/sandeep_rman_refresh/%U';
allocate channel d2 device type disk format '/dbaadm/sandeep_rman_refresh/%U';
allocate channel d3 device type disk format '/dbaadm/sandeep_rman_refresh/%U';
allocate channel d4 device type disk format '/dbaadm/sandeep_rman_refresh/%U';
allocate channel d5 device type disk format '/dbaadm/sandeep_rman_refresh/%U';
allocate channel d6 device type disk format '/dbaadm/sandeep_rman_refresh/%U';
CONFIGURE CONTROLFILE AUTOBACKUP ON;
CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '/dbaadm/sandeep_rman_refresh/%F';
backup as backupset database plus archivelog tag 'clonebackupset';
EOF
2) Make the directories for destination database ( rmsprd2 )
/opt/oracle/admin> mkdir -p rmsprd2/adump rmsprd2/dpdump rmsprd2/pfile rmsprd2/scripts
3) Create pfile from rmsprd1 spfile. copy/rename the pfile to make a pfile for rmsprd2.
4) Edit listener.ora in ASM ORACLE_HOME and edit tnsnames.ora in DB ORACLE_HOME
listener.ora
LISTENER_RMSPRD2 =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1522))
(ADDRESS = (PROTOCOL = TCP)(HOST = kirkjerpdb01.kirklands.com)(PORT = 1522))

(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = rmsprd2)
(UR = A)
5) Build a passwordfile ( I just copied and renamed it )
6) Edit /etc/oratab to add database entry for rmsprd2
7) Set the environment for rmsprd2
. oraenv
rmsprd2
8) Startup nomount of rmsprd2
sqlplus / as sysdba
startup nomount pfile=/opt/oracle/admin/rmsprd2/pfile/initrmsprd2.ora
9) Create spfile from pfile='/opt/oracle/admin/rmsprd2/pfile/initrmsprd2.ora';
10) shutdown and startup rmsprd2 with spfile
SQL> shutdown abort;
ORACLE instance shut down.
SQL> startup nomount;
ORACLE instance started.
Total System Global Area 1068937216 bytes
Fixed Size 2213632 bytes
Variable Size 788531456 bytes
Database Buffers 268435456 bytes
Redo Buffers 9756672 bytes
11) We are now ready for duplication from rmsprd1 ( source ) to rmsprd2 ( destination ) both using +ASM standalone asm instance. set the environment to rmsprd1and fire away.
Please note that the duplicate script is only connecting to auxilary database ( rmsprd2 ) and using the backup location for the duplication.
I used a unix shell script -rman_duplicate_from_backup.ksh. The contents are given below :
$ORACLE_HOME/bin/rman auxiliary sys/prd123@rmsprd2 log=rman_duplicate_from_backup.log << EOF
run
allocate auxiliary channel d1 device type disk;
allocate auxiliary channel d2 device type disk;
allocate auxiliary channel d3 device type disk;
allocate auxiliary channel d4 device type disk;
allocate auxiliary channel d5 device type disk;
allocate auxiliary channel d6 device type disk;
DUPLICATE DATABASE TO rmsprd2
BACKUP LOCATION '/dbaadm/sandeep_rman_refresh';
EOF
12) Voila - the rmsprd1 to rmsprd2 is done.....
Hope this helps somebody else wanting to do the same excercize. Have Fun.....
regards
Sandeep

Project files and Media files on same disk OK?

For some reason I have it in my head that having my project files on the same disk as I have the media files on is a bad idea.
Is that true? Thanks.

I haven't bothered separating this side of 2003 and haven't had any bottlenecks.. not from disk R/W anyway (CPU, memory.. another story). Unless you've got thousands of files and dozens of warp stabilisers in play your project file isn't going to be large enough to make a dent on disk access I reckon. A project file is, what.. 5 - 50 mb. That's a blip in the world of RED footage. Perhaps Adobe staff could reply on how intensively the project file is accessed during playback and editing?

Snow Leopard 10.6.1 Clone not appearing in Startup Disk

Before attempting to upgrade to 10.6.2, I made a bootable clone using Disk Utility of 10.6.1. I followed the same procedure I used successfully to create a bootable clone of 10.4.11 just a few days ago on a separate partition of my external drive. After finishing the SL clone of 10.6.1, I went to Startup Disk because I wanted to test if the computer would boot from it, but my new SL clone wasn't there--just my internal hard drive and the Tiger clone. I tried ejecting the external drive, then reconnecting it, and now neither the Snow Leopard nor the Tiger clones appear in Startup Disk. They do appear in Disk Utility, and I verified both of them, so Disk Utility says they're okay, but Startup Disk doesn't see them at all.

lakeshore wrote:
I tried resetting PRAM, but that did nothing. The only thing I did earlier that might have caused this is that when I originally partitioned the drive, I named the volumes "Tiger Clone" and "Snow Leopard Clone." While making the bootable clone of SL, I noticed that Disk Utility automatically changed the name of that volume to "Macintosh HD." So immediately after the clone was finished, I went into Get Info and changed the name of it back to "Snow Leopard Clone." Then I checked Startup Disk, and the SL clone wasn't there, but the "Tiger Clone" was. I then changed the name of "Tiger Clone" to "10.4.11" and that's when the Tiger Clone volume disappeared from Startup Disk. Could changing the names of the volumes have the effect of the volumes no longer showing up in Startup Disk?
this really should not matter. try this. run the following terminal command
sudo bless --folder /volumes/"Snow Leopard Clone"/System/Library/CoreServices --bootinfo --bootefi
you'll have to enter your admin password (which you won't see). that's normal. then see if it shows up in the startup disk preferences.
If I have to access those clones using the option-hold restart, which seems to work for me, that's fine. I just want to make sure that the two clones on my external drive are safe and bootable.

Can I install clone of system on same HD as Time Machine for a repair boot drive?

Can I install clone of system on same HD as Time Machine so I can use the external as a second boot?
I have an external connected to new iMac and installed Time Machine on it. I then realized that I cannot boot from TM so can I clone my system onto the same HD as the TM is on? For purpose of rebooting so I can use Disk Warrior or other diagnostics?
Thanks.
Jeff

I did try that but the only options I was ofered were:
Restore from Time Machine Backup
Reinstall OS X
Get Help Online
Disk Utility
I didn't want any of those options. I just wanted to boot from the external.
You used recovery option - that is not what you need for this. Follow lowluster's suggestion to create another partition on your external drive, then format it using Disk Utility if necessary (in your applications folder). After that, use CarbonCopyCloner or SuperDuper to create a bootable clone on the external while booted from the internal.
Didn't know TM was to be installed on internal boot. Thanks.
Isn't there an advantage to having it on an external as well?
Time Machine is an application program and installed on your internal by default. You activate it from there and it works on its own to create backups on an external drive. It backs up everything.

Can I restore OSX to a disk, from a backup that's on the same disk?

I have a Powermac G5 Quad, that has two internal drives. (a 250gb system drive, and a 500gb spare).
Both drives are now out of space. I want to purchase a 1TB drive to replace the 250 system drive.
Tell me if this plan makes any sense:
1. Remove the 500gb spare drive.
2. Install the 1 TB drive, format, & use it as the Time Machine backup disk for the system drive.
3. Once the backup is complete, Remove the 250gb system drive.
4. Boot to the 10.5 Install DVD, and select "restore from backup"
5. Use the Backup on the 1 TB Drive, to install the OS on the same disk.
It's step # 5 that I'm not sure will work. Can I install an OS to a disk, from a backup that's on the same disk?

Sorry it took me so long. I had a baby. Anyway, here's how it went down:
I attempted to use the disk utility to "Clone" the original 250gb system disk to the new 1tb Hard drive.
It did not work. Tried booting to the Leopard install disk, and doing it from there, no dice.
So, I went ahead and created 2 partitions on the new 1TB disk. One I called "Time Machine" and it was 300 gigs. The other I called "New System Disk".
I booted to the "Old" System disk, and set up Time Machine to back-up to the "Time Machine" partition. It took 5 hours to back up 250 gigs, but it worked.
I then booted to the 10.5 Install DVD. one of the utilities you can use is "Install from Time Machine Backup" This worked. Took about 5 hours to copy everything to the new "New System Disk".
When that was done, I removed the old system disk. It booted to the new system disk without any trouble.
I was now stuck with a "Time Machine" partition that I did not want. It was EXTRAORDINARILY EASY to delete that partition, then re-size the other one so it took up the entire 1 Terabyte of available space.
So, the answer to the question is: Yes, you can use Time Machine to restore to the same disk, provided that the disk is using two partitions.

IS THE SITUATION HOPELESS
I used Target mode to transfer files to a new i7 iMac running Snow Leopard 10.6.8 from an older Dual core Intel machine (EMC 2105) also on 10.6.8. but originally Tiger 10.4. The operation was successful and I ejected the disk icon from the new machine and powered down the old machine. When this was restarted the next day there was a grey screen with flashing Mac symbol alternating with a 'no entry' sign and occasionally a question mark.Keyboard and mouse were unusable so k inserted the original instal disc (No.1 for 10.4. with installer 1.0.4) which came with the machine in 2006 in an attempt to boot from this. The ensuing window said this was not possible and now it cannot be ejected.I have tried everything ! It offers Disk Utility and other options like Terminal but that doesn't work either.I 'repaired disk' and that was pronounced o.k. None of the various keystrokes at start up will work, and the computer will only offer the installer disc continually.The only option would seem to be is to erase the hard drive completely from the disc in the machine.I don't want to do this as there is still material which I need to recover. I think the drive has in some way been corrupted by using it in target mode, and I don't know if there are any other options to try.
Please tell me how to get this disc to eject !

Have you seen this type of problem before? I think it could be a serious issue for anyone in a similar position.
No; but then, I've not had occasion to use TDM. I've been using firerwire drives for over 10 years, both FW400 and FW800, with no issues except a bit of instability using a B&W G3 machine.
TDM should be safe. Using cautious, manual copying of files from the Target machine to the Host machine should not result in unexpected loss of files or damage to the Target drive's directories. It should behave exactly the same as if it were an external (to the Host) firewire drive.
• I don't suppose there is anything I can do to 'put back' lost items from a separate Time Machine drive which has an up to date backup on it.
There is probably a way to do that - seems to me that's one of the reasons for a Time Machine volume.
On the other hand, if the Time Machine volume is rigidly linked to the now-absent OS on the original drive, there may be no way to effectively access the files in the TM archive.
I know that using a cloned drive would work well in this instance.
I have no experience with Time Machine, so perhaps someone who has will chime in with suggestions.
With the machine in TDM with the other machine, have you tried running Disk Utility to see if you can effect repairs to the drive?
