Can I run a second Time Machine on one computer?

Hi guys,
Is there any way I can run two Time Machines for one computer? I want to have one external Time Machine backup sitting on my desk, and another stored offsite for safe keeping, then swap them over every few days so that they are both generally up to date.
Any ideas?

not across internet. you can back up across local network to a Time Capsule, a drive connected to Airport extreme base station or another mac running leopard, leopard server or a Xsan storage device. all other network backups are unsupported. and it's definitely not possible to do it over internet.

Plug an external drive into the computer and use that to expand data onto.

Two computers backed up on the same Time machine disk, one computer is dead. How to access data?

Hi guys,
I backed up two different computers on the same time machine disk. Now, one of my computer is dead. I can see the backups on my time machine disk. How can I get the backup data that belongs to dead computer. When I enter time machine, I only have access to corresponding backup. I do not want to destroy the backups. My timemachine backup structure looks like below:
-->Backups.backupdb
-->Computer-1
-->Computer-2
Now, my Computer-1 is dead, and I am using Compter-2. If possible I wan to know a way of accessing Computer-1 data without destroying any other backups/files etc. Than you!

I loathe sending people offsite for information except WRT time machine. The late James Pond was a master at all things Time Machine related...maybe more....may he rest in peace for his contributions to ASC.

Can you run multiple versions of Message on one computer, i.e. one for each phone line on our account?

Does anyone know if you can run more than one Message+ on one computer, one for each of our phones?

CATTULLOS
Great question! The way to do it is, you will need to open up multiple browsers. (one for each phone number) The only thing you would need to do is log into www.vzw.com for each individual number to be able to send the text messages. Keep us posted let us know if this helps.

TS1963 migrating documents in time machine from one computer to a different one

the transfer seemed to work well and I found the files on my new computer but it says i don't have permission to open the files. All the transferred files have a red circle with a line through it. So even though I have the files they're unavailable to me to open.... my question is how to I open them????

To prevent a sync when plugging in the iPod/iPhone - hold down the 'option' and the 'command' keys when plugging in the ipod - key the keys down until the iPod/iPhone is listed under the Devices list in iTunes - this will prevent a sync from taking place and you will be able to change your settings.
Using Migration Assistant would have been an easier option then you could have deleted the stuff you didn't want on the new Mac.

I need to back up my imac running Tiger (no time machine) so that we can upgrade OS. It is set up for multiple accounts. How do I capture all files in each account using newly purchased USB external hard drive?

Can use old macbook for Time Machine Backup?

Have an old macbook running snow leopard. Can I use it for Time Machine Back-up for my current macbook pro?

Boot your old into Target Disk mode, then plug a FireWire cable from your old to your pro. Presto! Your old's internal HD will appear in your pro's Finder as a disk on your pro. Time machine running on your pro can use it for backup. Time machine won't disturb its contents, except to add a potentially huge folder there, which will grow to fill the disk with copies of your backups. (Backing up, then) partitioning (and then restoring from backup) your old's internal hard drive will keep your pro's Time Machine from consuming all free space.

Can't Find File in Time Machine

Kind of a weird problem, usually I can figure this stuff out on my own.
Basically, I have an edited version of a video and I want to retrieve the original. I know I did the edit on that day and I know its date created. I have a weekly backup from that week and the week after. In the one for that week, neither the original nor the edit are present so I assume the end of that week was right before I moved the video onto my computer. The next backup has the editied version, but the original is nowhere to be found, so I'm assuming that I can't get at in any way, so basically my question is.
1. Does Time Machine back up the trash anywhere? The .trash file isn't in my ~/ so I'm assuming it doesn't, and the file might have been in the trash.
2. How does Time Machine compress the backups into weekly files? Is it possible that something that only existed on my hard drive for a very short period of time got "dropped" in the combining process? Or did I somehow manage to get it onto my computer and delete it between backups?

1. Does Time Machine back up the trash anywhere?
No, that's one of the things it skips automatically. See What's excluded from backups in #11 of Time Machine - Frequently Asked Questions.
2. How does Time Machine compress the backups into weekly files?
It doesn't, exactly. It simply deletes the backups that have "expired." That leaves a "snapshot" of how your entire Mac looked at the time of each remaining backup.
Is it possible that something that only existed on my hard drive for a very short period of time got "dropped" in the combining process? Or did I somehow manage to get it onto my computer and delete it between backups?
Yes, it's quite possible. It depends on the timing and how often backups are run, but basically Time Machine keeps all backups for 24 hours, except the first of the day, which is kept for a month. After a month, it keeps one per week.

Time machine is not working. I get a message: You can't open the application "Time Machine" because it may be damaged or incomplete.

Time machine is not working under "Applications". I get this message: You can’t open the application “Time Machine” because it may be damaged or incomplete. What do I do?
Time machine under system preferences lets me setup time capsule. But backup fails because "Volume is in use" Help please!

It does sound like you have a corrupted install.
The volume in use error is something we see all the time.
Look at C12 here. http://pondini.org/TM/Troubleshooting.html
But I suspect you have more serious issue.
I would run a disk verify on your local OS disk. A5 in the above reference has some info.

I am running my first time machine backup onto a Western Digital MyBook Live. It is taking forever. Is there antivirus software running in the background or any other settings I need to change to speed it up? Also I am on a wireless network.

I am running my first time machine backup onto a Western Digital MyBook Live. It is taking forever. Is there antivirus software running in the background or any other settings I need to change to speed it up? Also I am on a wireless network.

The initial Time Machine backup can certainly take a long time over wireless. Days, possibly. It's impossible for anyone here to be able to predict how long it will take, and wireless environmental conditions can change at any time.
Is there antivirus software running in the background
Only you can determine that. If you're using third party AV software, anything is possible.
NAS devices may not be compatible with Time Machine, regardless of what their manufacturers may claim. Even after the Time Machine backup completes, your backup may be unreliable. You may not discover that until you need to rely upon the backup for some reason, and corruption can occur months or years from now.
Time Machine supports the following backup configurations:
A locally mounted volume
Time Capsule
A volume resident on a USB hard disk connected directly to a Time Capsule or current production AirPort Extreme Base Station.
That's it. Any configuration other than the above list places you in an experimental category. If your backup fails, you're on your own.

Can you boot up using time machine

can you boot up using time machine? have continuous grey screen at startup.

Time Capsule TC = hardware router and hard disk designed to work with Time Machine.
Time Machine TM = software in the computer designed to run background backup.
What you buy is a Time Capsule..
And yes, that is the whole point of the TC..
Its fundamental design is a backup device for laptops over wireless so they do not need to be plugged in to do backups.
You are using it exactly for the intended use.

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 How can I exclude mail from Time Machine backups?

How can I exclude mail from Time Machine backups?

Welcome to the Apple Support Communities
Mails are stored on ~/Library/Mail, being ~ your user folder. As you are running Snow Leopard, it's easy to exclude your mails from your Time Machine backup.
Open System Preferences > Time Machine > Options, and add ~/Library/Mail to excluded items, so the next backup won't include mails. Note that you have to go to your user folder, in order to access to this directory

Can I do it with time machine?

I have an older mac with snow leopard and I just bought a new AIR with Lion. Is there a way to transfer everything including programs that are work related on to the new machine? Can I do it with time machine?

The Macbook Air doesn't have Firewire ports, it has USB only, or wireless ethernet. (You can also use ethernet wired through a USB-ethernet adaptor but I think this is rarely done.)
I did this Migration when we got a new Macbook Air last year. The Apple Store people told me that they strongly recommended doing this Migration to the new Macbook Air through USB with the Time Machine backup. They said this was the most likely approach to be complication-free. They also told me that when someone brings in an older machine to them to be migrated to a new one (they offer this service for $75), they even create the Time Machine backup right there to use in the transfer because it works so smoothly.
I did it the way they recommended, USB between old Time Machine backup to USB on new Macbook Air. It took a few hours (200 GB to transfer) and was completely trouble free. I did have to reinstall the printer drivers for a Canon printer/scanner. Otherwise, everything was there and we didn't even have to enter serial numbers for MS-Office or Adobe software like photoshop.
So that's my recommendation to you for the Macbook Air. Wireless ethernet is another option but it's more complicated and more prone to issues, and it's much slower.
One thing you should be awae of -- certain older software runs under "Rosetta" under 10.6, but Rosetta is gone under 10.7, so those programs won't work under 10.7. One example is MS-Office 2004. On the other hand, Office 2011 works fine under 10.7.
