Can I have 2 Separate Time Machine backups on one Mac?

I have a Mac running Snow leopard which I keep connected to an external USB drive. That drive is set up to automatically back my machine through Time Machine and it works great.
I would like to also do a backup of my machine and all its files onto a portable USB drive that I can then take to the office (i.e. remove it from the house) for security purposes. Once every couple of weeks I would plan on bringing the portable USB drive back home, plugging it into the Mac, doing another Time Machine backup and then removing it again.
Can I have 2 separate Time Machine backups onto 2 separate hard drives (as described above) on a single Mac?

Well I tried it, and it worked.

HT201250 Can I copy a time machine backup from one mac to another?

I have two Mac Book Pros that I use for work - I have one at home and one at work. I'd like to copy the contents and setup from my work Mac to my home Mac using a time machine backup, and then continue to use the time machine backup back at work. I.e. the time machine would only be used with the home Mac to copy over the contents and setup of my work Mac.
Can I just do a straight time machine back up in my 2nd (home) mac, or will this override the back up I have from the 1st (work) machine?
Thanks!

Welcome to Apple Support Communities
Of course. Note that you can restore a Time Machine backup on all the Macs you want, always that the Mac uses the same or a newer OS X version than the one that had the Mac you used to make this backup.
Also, you can back up different computers to the same Time Machine drive. In this case, Time Machine will create different folders in your Time Machine drive for each computer, so one Mac backup won't conflict with the other computer backup.
To restore a backup, use Migration Assistant. Just connect the Time Machine drive, open Migration Assistant (it's in /Applications/Utilities) and follow the steps to restore the backup onto the computer

Can I have two Time Machine backup external drives on one Mac?

I have been using Time Machine for over a year and like it very much. The thought occurred to me that I should buy a new external drive that I can backup to and store at a remote location. I plan on making a backup each week, then taking this new drive to my office. That way, if my house ever burns down, I have a backup at my office too that will be a fairly recent backup.
When I unplugged my older external drive and tried to launch a backup using the new one, my Mac said it couldn't find my Time Machine drive. Won't it let me backup to two different drives? Or does it always need to backup to the same one?
Thanks!

Yes. All you have to do is tell it you've changed destinations, via +Time Machine Preferences > Select Disk.+ (Use different names for the drives, so you know which one is which.)
Try not to go too long between "swaps," though. After several days, especially if there's been a large volume of changes, Time Machine might do a new, full backup, instead of an incremental one.
However, I've learned over the years (mostly the hard way, of course ), never to trust my backups to a single app or piece of hardware: no app is perfect, and all hardware fails, sooner or later.
Like many here, I keep both full Time Machine backups, plus a "bootable clone" on a separate external HD. I use CarbonCopyCloner, many use the similar SuperDuper. That gives me the best of both types of backups, plus of course a completely separate, independent backup.
CCC is donationware; SD has a free version, but you need the paid one (about $30) to do updates instead of full replacements, or scheduling. Either is easily found via Google.
And/or, see Kappy's post on Basic Backup, complete with links to the web sites of each product.

Using Time Machine backup from one mac to another

I had a Mac book pro running 10.7.5 and used Time Machine to backup the system. The macbook died and I want to restore the Time Machine backup to my iMac running 10.7.5.
Question 1: Is this possible and how is it done?
Question 2: Will it restore all the software and files from the macbook pro to my iMac?

It can be done without any problem and everything will be restored from the Time Machine backup.
If you want to replace the actual content of the hard drive of your iMac with the content of the Time Machine backup, press Command and R keys while your Mac is starting, choose the option to restore the Time Machine backup and follow the steps.
If you want to keep both content, use Migration Assistant to create a new user with the data of the MacBook Pro. Open Migration Assistant and follow the steps. Then, open  > Log Out, and log in the new user to access to the migrated data

Restoring a time machine backup from a Mac mini to a new Mac mini server

Hi,
I just replaced a faulty Mac mini with a Mac mini server. I have a time machine backup of my Mac mini and want to transfer it over to the Mac mini. How do I do this?

This is a bit of a guess... But I Imagine you would have to start with the workstation OS install DVD first, and go from there at the appropriate point. Any chance you have or could make a CCC backup instead? I am assuming you could boot a mini server from a backup of mini non-server. Then you could copy it over. This is probably worth a phone call to Apple TAC

I am out of space on my Macbook Air and have a Time Machine Backup. I want to complete reset my mac, but wonder if I can pick and choose what I restore to my computer? Can I also use my time machine backup and external storage as well?

I am out of space on my Macbook Air and have a Time Machine Backup. I want to complete reset my mac, but wonder if I can pick and choose what I restore to my computer? Can I also use my time machine backup as external storage as well for the files I don't need everyday?

If you are using "Restore from Time Machine Backup" option from OS X Recovery, you can only choose from the broad categories presented.
... Can I also use my time machine backup as external storage as well for the files I don't need everyday?
To be clear, if you are asking if you can use the volume containing your Time Machine backup to store additional, non-Time Machine files, the short answer is yes.
It's not a good idea though, since the Time Machine backup will eventually fill all available space, after which it begins to remove old, "expired" backups to make room for newer ones. The presence of additional files doesn't change that fact, and Time Machine will not erase them, but you will encounter a dilemma should you want to store additional files on that volume when there is no remaining space. You will have to make room for them on your own, by deleting existing files. Furthermore, since Time Machine cannot back up its own volume, those additional files will not be backed up by Time Machine.
The easy solution for what you describe is to purchase additional external storage. External USB hard disk drives have become very inexpensive; about $55 will buy a perfectly suitable 1 TB drive.
You can also choose to replace your MacBook Air's internal storage with a larger capacity one. Look for a suitable replacement from OWC / MacSales:

That gets a little more expensive but it is the optimum solution.

If I update from 10.6.8 to Mavericks and I have a time machine backup, can I do a full restore back to 10.6.8 and resume as if I had never updated?

If I update from 10.6.8 to Mavericks and I have a time machine backup, can I do a full restore back to 10.6.8 and resume as if I had never updated if there is a problem? Probably an answer I should know but I don't. Thanks in advance! (instruction suggestions welcomed)

Upgrading the OS is a system wide thing. So all users will receive the upgrade.
It should not delete files and such. However, if you have for example files made with Pages '09. Then the new Pages that comes with Mavericks will make a copy of those files so you can continue to edit them. But those new files can not be opened in Pages '09. BUT again, some people perfer Pages '09 and they use that still. Mavericks will just hide Pages '09, it's still usable in Mavericks just hidden.
To be safe, make a back up of your system before doing any major upgrade.

Can I have 2 Time Machines for 2 backups?

I have an external hard drive that I use for my time machine. Recently I've been having some problems with my iMac that are hard drive related. I wasn't able to repair using disk utility and had to erase and reinstall Snow Leopard and then transfer everything back from time machine.
After this I realize just how fragile this all is. I have many photos and videos of my family from years ago and was relieved that I had everything backed up. Hard drives are so inexpensive these days, I feel it may be wise to have another backup in the unlikely event both hard drives were to have problems at the same time.
Can I have two Time Machines? If not, what are my options?
Thanks for any suggestions on this topic.

Yes, but not simultaneously. You can switch the desired backup drive using TM preferences, but TM cannot backup to two drives concurrently. However, I would suggest not using TM for your second backup. Instead consider making a bootable clone on the second drive. You can then use a third-party backup utility to incrementally update the clone. Because this software is running independently of TM you can have both a TM backup and a third-party backup. With TM backing up hourly you can set the second backup schedule to backup weekly and/or monthly.
If something does go amiss with your main system drive, then you can boot from your clone in order to restore function to the main drive.
To avoid using up space on the TM drive be sure you add your second backup drive to the TM Exclude list.
Basic Backup
Get an external Firewire or USB drive at least equal in size to the internal hard drive and make (and maintain) a bootable clone/backup. (Note: Most PPC Macs cannot be booted from a USB drive.) You can make a bootable clone using the Restore option of Disk Utility. You can also make and maintain clones with good backup software. My personal recommendations are (order is not significant):
1. Retrospect Desktop (Commercial)
2. Synchronize! Pro X (Commercial)
3. Synk (Backup, Standard, or Pro)
4. Deja Vu (Shareware)
5. Carbon Copy Cloner (Donationware)
6. SuperDuper! (Commercial)
7. Intego Personal Backup (Commercial)
8. Data Backup (Commercial)
9. SilverKeeper 2.0 (Freeware)
10. MimMac (Commercial)
11. Tri-Backup (Commercial)
Visit The XLab FAQs and read the FAQ on backup and restore. Also read How to Back Up and Restore Your Files.
Although you can buy a complete FireWire drive system, you can also put one together if you are so inclined. It's relatively easy and only requires a Phillips head screwdriver (typically.) You can purchase hard drives separately. This gives you an opportunity to shop for the best prices on a hard drive of your choice. Reliable brands include Seagate, Hitachi, Western Digital, Toshiba, and Fujitsu. You can find reviews and benchmarks on many drives at Storage Review.
Enclosures for FireWire and USB are readily available. You can find only FireWire enclosures, only USB enclosures, and enclosures that feature multiple ports. I would stress getting enclosures that use the Oxford chipsets (911, 921, 922, for example.) You can find enclosures at places such as;
Cool Drives
OWC
WiebeTech
Firewire Direct
California Drives
NewEgg
All you need do is remove a case cover, mount the hard drive in the enclosure and connect the cables, then re-attach the case cover. Usually the only tool required is a small or medium Phillips screwdriver.

no archive/ backup is perfect, HD clones can be set to make incremental additions, same as time machine however, though they are more time involved in doing so.

Data Storage Platforms; their Drawbacks & Advantages
#1. Time Machine / Time Capsule
Drawbacks:
1. Time Machine is not bootable, if your internal drive fails, you cannot access files or boot from TM directly from the dead computer.
2. Time machine is controlled by complex software, and while you can delve into the TM backup database for specific file(s) extraction, this is not ideal or desirable.
3. Time machine can and does have the potential for many error codes in which data corruption can occur and your important backup files may not be saved correctly, at all, or even damaged. This extra link of failure in placing software between your data and its recovery is a point of risk and failure. A HD clone is not subject to these errors.
4. Time machine mirrors your internal HD, in which cases of data corruption, this corruption can immediately spread to the backup as the two are linked. TM is perpetually connected (or often) to your computer, and corruption spread to corruption, without isolation, which TM lacks (usually), migrating errors or corruption is either automatic or extremely easy to unwittingly do.
5. Time Machine does not keep endless copies of changed or deleted data, and you are often not notified when it deletes them; likewise you may accidently delete files off your computer and this accident is mirrored on TM.
6. Restoring from TM is quite time intensive.
7. TM is a backup and not a data archive, and therefore by definition a low-level security of vital/important data.
8. TM working premise is a “black box” backup of OS, APPS, settings, and vital data that nearly 100% of users never verify until an emergency hits or their computers internal SSD or HD that is corrupt or dead and this is an extremely bad working premise on vital data.
9. Given that data created and stored is growing exponentially, the fact that TM operates as a “store-it-all” backup nexus makes TM inherently incapable to easily backup massive amounts of data, nor is doing so a good idea.
10. TM working premise is a backup of a users system and active working data, and NOT massive amounts of static data, yet most users never take this into consideration, making TM a high-risk locus of data “bloat”.
11. In the case of Time Capsule, wifi data storage is a less than ideal premise given possible wireless data corruption.
12. TM like all HD-based data is subject to ferromagnetic and mechanical failure.
13. *Level-1 security of your vital data.
Advantages:
1. TM is very easy to use either in automatic mode or in 1-click backups.
2. TM is a perfect novice level simplex backup single-layer security save against internal HD failure or corruption.
3. TM can easily provide a seamless no-gap policy of active data that is often not easily capable in HD clones or HD archives (only if the user is lazy is making data saves).
#2. HD archives
Drawbacks:
1. Like all HD-based data is subject to ferromagnetic and mechanical failure.
2. Unless the user ritually copies working active data to HD external archives, then there is a time-gap of potential missing data; as such users must be proactive in archiving data that is being worked on or recently saved or created.
Advantages:
1. Fills the gap left in a week or 2-week-old HD clone, as an example.
2. Simplex no-software data storage that is isolated and autonomous from the computer (in most cases).
3. HD archives are the best idealized storage source for storing huge and multi-terabytes of data.
4. Best-idealized 1st platform redundancy for data protection.
5. *Perfect primary tier and level-2 security of your vital data.
#3. HD clones (see below for full advantages / drawbacks)
Drawbacks:
1. HD clones can be incrementally updated to hourly or daily, however this is time consuming and HD clones are, often, a week or more old, in which case data between today and the most fresh HD clone can and would be lost (however this gap is filled by use of HD archives listed above or by a TM backup).
2. Like all HD-based data is subject to ferromagnetic and mechanical failure.
Advantages:
1. HD clones are the best, quickest way to get back to 100% full operation in mere seconds.
2. Once a HD clone is created, the creation software (Carbon Copy Cloner or SuperDuper) is no longer needed whatsoever, and unlike TM, which requires complex software for its operational transference of data, a HD clone is its own bootable entity.
3. HD clones are unconnected and isolated from recent corruption.
4. HD clones allow a “portable copy” of your computer that you can likewise connect to another same Mac and have all your APPS and data at hand, which is extremely useful.
5. Rather than, as many users do, thinking of a HD clone as a “complimentary backup” to the use of TM, a HD clone is superior to TM both in ease of returning to 100% quickly, and its autonomous nature; while each has its place, TM can and does fill the gap in, say, a 2 week old clone. As an analogy, the HD clone itself is the brick wall of protection, whereas TM can be thought of as the mortar, which will fill any cracks in data on a week, 2-week, or 1-month old HD clone.
6. Best-idealized 2nd platform redundancy for data protection, and 1st level for system restore of your computers internal HD. (Time machine being 2nd level for system restore of the computer’s internal HD).
7. *Level-2 security of your vital data.
HD cloning software options:
1. SuperDuper HD cloning software APP (free)
2. Carbon Copy Cloner APP (will copy the recovery partition as well)
3. Disk utility HD bootable clone.
#4. Online archives
Drawbacks:
1. Subject to server failure or due to non-payment of your hosting account, it can be suspended.
2. Subject, due to lack of security on your part, to being attacked and hacked/erased.
Advantages:
1. In case of house fire, etc. your data is safe.
2. In travels, and propagating files to friends and likewise, a mere link by email is all that is needed and no large media needs to be sent across the net.
3. Online archives are the perfect and best-idealized 3rd platform redundancy for data protection.
4. Supremely useful in data isolation from backups and local archives in being online and offsite for long-distance security in isolation.
5. *Level-1.5 security of your vital data.
#5. DVD professional archival media
Drawbacks:
1. DVD single-layer disks are limited to 4.7Gigabytes of data.
2. DVD media are, given rough handling, prone to scratches and light-degradation if not stored correctly.
Advantages:
1. Archival DVD professional blank media is rated for in excess of 100+ years.
2. DVD is not subject to mechanical breakdown.
3. DVD archival media is not subject to ferromagnetic degradation.
4. DVD archival media correctly sleeved and stored is currently a supreme storage method of archiving vital data.
5. DVD media is once written and therefore free of data corruption if the write is correct.
6. DVD media is the perfect ideal for “freezing” and isolating old copies of data for reference in case newer generations of data become corrupted and an older copy is needed to revert to.
7. Best-idealized 4th platform redundancy for data protection.
8. *Level-3 (highest) security of your vital data.
[*Level-4 data security under development as once-written metallic plates and synthetic sapphire and likewise ultra-long-term data storage]
#6. Cloud based storage
Drawbacks:
1. Cloud storage can only be quasi-possessed.
2. No genuine true security and privacy of data.
3. Should never be considered for vital data storage or especially long-term.
4. *Level-0 security of your vital data.
Advantages:
1. Quick, easy and cheap storage location for simplex files for transfer to keep on hand and yet off the computer.
2. Easy source for small-file data sharing.

I have a time machine backup file on a USB hard drive. I bought a time capsule / airport extreme, flat 3TB. I wish to transfer the backup file from the usb hard drive to the time capsule hard drive. 10.6.8

I have a time machine backup file on a USB hard drive. I bought a time capsule / airport extreme, flat 3TB. I wish to transfer the backup file from the usb hard drive to the time capsule hard drive. 10.6.8

Unfortunately, Time Machine backups that are stored on a drive that has been connected directly to a Mac are completely different than Time Machine backups that are stored on a Time Capsule.
Frankly, it is not worth the effort and trouble to try to transfer the old backups to the new Time Capsule.....my opinion....having done this in the past.
It is possible though, but I would not recommend it due to the complexity and downsides involved with this. To give you an idea of how to do this, check out this support article.
http://pondini.org/TM/18.html
Even if you transfer the "old" backups over to the Time Capsule successfully, Time Machine will not simply "add on" to the old backups.
Time Machine will make a new complete backup of your Mac and then add incremental backups from that point.
My advice.....start a new backup on the Time Capsule and move forward. Keep the USB hard drive around for a month, maybe 2 or 3 in case you need to go back to an old backup for some reason. At that time, you will not likely need the old backups at all since you will have a current 2-3 month history of new backups. At that point, you can erase the USB drive and use it for another purpose.

Can I have several Time Machines in Mavericks?

I have several boot partitions over several disks. Am I allowed to have more than one Time Machine partition - each backing up different drives?
The same question was ever asked against Snow Leopard here, and the answer was no, "You can't have more than one Time Machine destination disk active at any one time."
Is it still the same limit today for Mavericks?
I have 1 x SSD and 3 x HDD, I just want to use one 1TB HD to back up the 500GB SSD, and the 4TB HD to back up the 2TB HD.
Possible please?
Thanks heaps in advance.

Called Apple Care Support and confirmed that only one Time Machine backup can be active, in other words, only one destination drive can used to perform Time Machine backup automatically.
Therefore I had to hoose the largest internal HD (4 TB) to back up all other drives (total 2.5 TB).

Is possible to have a time machine backup on an external hd connected to either a primary or secondary router and not have "back to my mac" using 10.7.3?

Is possible to have a time machine backup on an external hd connected to either a primary or secondary router and not have "back to my mac" using 10.7.3?

The bottom line is that Apple does not support Time Machine backups at the USB port of the AirPort Extreme. If they don't support their own router, they certainly don't support other routers from other manufacturers.
Connect the drive directly to the Mac using either USB or FireWire.....or....use a Time Capsule. Either of these setups will be supported.
If you want to try the unsupported method(s), you can certainly do so. But, I would suggest that you have a secondary backup plan in place if this is important data that you will be backing up.

Hi iVain
Fire up *Disk Utility*, click the Restore tab, then drag your old and new TM drives into the Source and Destination fields. Click Restore, and a complete copy of your old TM files will be made on the new drive. Go to TM preferences and select the new drive, and it will continue backing up just as it left off.
Hope this answers your question. See:

Can I transfer a Time Machine backup to a new empty hard drive, without installing Mountain Lion again?

Can I transfer a Time Machine backup to a new empty hard drive, without installing Mountain Lion on that new hard drive?

Yes - I just did it the other night. Took five hours, but it finally finished and is working great.
I sort of followed the instructions found here -->> http://pondini.org/TM/18.html.
Also, if you want to have dual backups, see -->>
http://pondini.org/TM/27.html.
I say 'sort of' because I used Carbon Copy Cloner to do a block-level transfer. I just didn't want to get hung up with a Finder copy.
Give CCC a try - you have to enable the block copy in Preferences before using this method, but I was quite happy with it. I used it to move over 1TB of TM backups from a FireWire 800 drive to a 2TB Thunderbolt drive. 5 seconds short of taking 5 hours.
It should work well for you.
