Thinking of using Time Machine. Can you purge the external drive?

I currently have a 500gb external drive that I use with the software that came with it. It has a feature that I run manually from time to time that purges any files not on my computer. This is helpful for those times when I have many old project files, podcasts, etc, that were backed up but no longer needed.
I am thinking of buying one of the new Time Capsules to use with Time Machine just b/c I could use a new larger drive.
Question: Does Time Machine have a pretty easy purge feature? I've been reading and haven't found the answer just yet.
Thanks.

Thanks for the message.
What I mean is that on my current drive, I can click a button that reads "purge" and the software will either "mass delete" all files no longer present on my computer or it will allow me, one by one, to approve their deletion. It does then when I want (not only when the drive is full).
From what I'm gathering, Time Machine decides for itself what to delete only when the drive is getting full?
Thanks.

Can I use Time Machine to archive like an external drive?

I've backed up my computer to Time Machine and everything from my computer is there, but I have a new project which needs me to archive 21 pieces of artowrk that have multiple photo images for aech, and they are large size originals. Can I upload these files to a folder in Time Machine or directly on my external drive, so I don't have to have all of these files taking up space on my main computer?

You can, but it is not recommended.
Apparently you cannot partition an existing Time Capsule volume if that is what you are using.
Excerpt from ASC contributor Pondini's Time Machine FAQ:
3. Can I use my TM disk for other stuff?
Yes. Time Machine will not delete anything you put there.
But it's much, much better to partition an external drive into 2 (or more) parts, also called volumes. Assign one to Time Machine, for its exclusive use for backups; use the other partition(s) however you want.
(Unfortunately, though, you can't partition a Time Capsule's internal disk. See #Q3 in Using Time Machine with a Time Capsule for some alternatives)

Using Time Machine to back up an external drive?

I have an external HD containing my iTunes library attached to my Airport Extreme Base Station. Is it possible to use Time Machine to back up the AEBS-attached HD onto a different HD? I would connect the new HD directly to my MacBook and in an ideal situation, Time Machine would create a fresh back-up of my AEBS HD (iTunes library) every time I connected the second HD to my MacBook.
I may be making this more difficult than it needs to be. I just want to be able to back up my iTunes library to a second HD which I still have to purchase.
Any ideas?

Yes, just be sure the drive is online and not in the exclude list. Note that TM can only backup to one designated backup drive. If you add a second drive for backup, TM cannot use it and the currently designated backup drive simultaneously.

Using time machine - can you go back restore then come back to now and restore again?

Hi
Sorry if this has been answered elsewhere.
I just did the latest upgrade to Snow Leopard that came out in the last week or so and my old Australian Tax Office software program called e-Record 6 no longer works.
I have Time Machine.
I have a really dumb question.
If I go back in time to before I did the upgrade - and do a restore - do I also lose all the work and emails etc etc that I have done between then and now?
I want to go back in time - to the old version of snow leopard so that my old software works again. While I am there I want to export all the data out of the program into a spreadsheet and print out all the records so I have them as a hard copy (so I an actually lodge a tax return) and then I want to just come straight back to now and keep going. I don't want to lose any of the work or emails I have worked on over the past week.
Once you restore a to a time past can you then restore to a later backup - say today?
I hope I am making sense.
I really just want to time travel briefly.
TIA

I'm not sure about the TM question; you can try reading Pondinin's TM FAQs to see if it gives a clue.
First, though, try the v1.1 update which is supposed to have fixed the issue with Rosetta created by the original version.
If that doesn't fix it, there are a number of threads with possible solutions - this one is typical;

Using time machine to back up additional external drives

My mac mini contains a 160 gb hard drive. Aiming to keep this free, I connected a 500 gb WD mac-specific hard drive. I also use this drive when attempting to access work files on my macbook pro. When using time machine, which backs up to a 1 TB WD hard drive (also attached to the mac mini), I cannot figure out how to use time machine to back up simultaneously the contents of the native (160 gb) drive in the mac mini and the contents of the portable external drive (500 gb). *Is there any way to set time machine to accomplish this?* Please help - I really need to continually back up the contents of the portable drive as well.

carbon copy cloner will do this. you set up a scheduled job (can be daily, weekly, etc. & even every hour!) & is free to use (donations accepted).

Can I use Time Machine to backup ONLY an external drive?

I am having problems with the internal HD on my iMac and Disk Utility is telling me I need to reformat the drive and restore from backup. Only problem is that my 3TB Lacie Thunderbolt drive I was using for Time Machine recently failed (think it may have happened during an electrical storm brownout). Yep, I know, ***** to be me
The issues with the internal HD are preventing the iMac from booting and I would prefer not to have to purchase various repair software to find one that really works such as Disk Warrior or similar ((despite it getting very good reviews). I suspect it make be HFS corruption but no way to really tell that I am aware of.
I have setup an external drive with Yosemite and booted from that so now my old internal drive is seen as an "external drive".
I am using Disk Utility to make an image copy to a new 3TB external drive I purchased. Writing the DMG is going to take some time.
What I would like to do is to set up Time Machine to backup to a separate external 3TB hard drive (the second one I purchased) and have TM create a backup of ONLY the old internal drive - not the new system as well as the old internal unit.
Is this possible and if so can anyone advise how to do this. Does not seem I can exclude the system drive I am now booted from so that it is not backed up. (This makes sense that TM would be designed this way given its primary purpose is to backup a system).
If TM cannot be configured in this way, is there another option I can use?
Thanks
Andrew

Thanks for that advice. I have heard of it but a friend who does IT support at a University nearby suggested using Disk Utility to save an image - hence this is currently underway at present. Once this is finished I will try Carbon Copy Cloner.
I have another friend who has an older version of CCC - do you know if an old version will work ok or if only the latest supports Yosemite?
Also once I have the clone completed from CCC, is the process then to reformat the old internal drive and then clone from the CCC external drive back to the internal and then reboot and trust all is well?
Appreciate your help Csound1.
Regards
Andrew

Time Machine can not be mounted - external drive

I have an external Maxtor USB drive that's been my time machine since forever. Yesterday I noticed that it's not mounting. I KNOW it was mounting the day before because I had to use it. But now the drive is not mounting, and I don't know why.
The drive is on, the light is on, but it's not mounting. Out of curiosity, my husband hooked it up to his Vista PC and he was able to browse to it all dandy. But then back on my computer, it's not being recognized.
It's not showing up in disk utility, though my other external drive, my iphoto drive, is having no problems. It's not the USB port, as my ipod works on either port, as does my iphoto drive.
Can anyone help?
I've unplugged it, plugged it back in. Rebooted the computer without it attached.

I solved my problem. I tried plugging it into another computer and it popped up on the screen. AHA! Before I tried that, I had ONLY unplugged the drive but had NOT crawled under the desk to unplug it from the main power source. It just needed to be TOTALLY unplugged and left alone for a few minutes. Those little green men obviously can bunch up anywhere and need a total disconnect, for several minutes at least, to unbind. Ahh, sort of like un-constipating the system?

HT201250 How do I use Time Machine to back up an External Drive to another External Drive?

Hello,
I have two 8TB Western Digital External Hard Drives with Thunderbolt ports. I have already set up a 500GB G-TECH Mini to use as the Time Machine backup for my MacBook Pro. Now, I would like to set up one of my 8TB drives to be the back up for my other 8TB drive, yet I seem to only be able to back up the MacBook Pro with Time Machine.
Any advice would be greatly appreciated.
Thanks!

Connect both 8TB externals to the computer, then do the following:
Clone using Restore Option of Disk Utility
1. Open Disk Utility in the Utilities folder.
2. Select the destination volume from the left side list.
3. Click on the Restore tab in the DU main window.
4. Select the destination volume from the left side list and drag
it to the Destination entry field.
5. Select the source volume from the left side list and drag it to
the Source entry field.
6. Double-check you got it right, then click on the Restore button.
Destination means the 8TB drive to which you will copy. Source means the 8TB drive you will copy.

Can you unplug the external hard drive you are using for time machine

can you unplug the external hard drive you are using for time machine and then plug it back in and it work normals because i have a mac book and don't want to always be carrieing the external hard drive every where i go so can you ?

Yes, that will work fine. It will back up normally once you plug it in again. I do this with my MacBook.

If time machine puts all of my photos onto my external hard drive using time machine, can I then delete the photos from my computer but view them again from the external hard drive? Basically, can I free up space on my mac but not lose years of photos?

To add to Niel's comment bear in mind that if you have a backup copy on an external HD and later delete the orignals on your Mac HD you will then only have one copy - so no backup.
If the pictures are precious you should have at least two copies, and ideally another copy kept off site,

HT201250 I've just used an external drive to back up my Mac with Time Machine. I have Lion, but didn't click and check the "Encrypt Backup Disc". What should I do? Can I delete the external drive and start again, or can I encrypt later?

I've just used an external drive to back up my Mac with Time Machine. I have Lion, but didn't click and check the "Encrypt Backup Disc". What should I do? Can I delete the external drive and start again, or can I encrypt later?

I guess if stolen or lost it would protect my "stuff", and if I'm travelling would protect my privacy.
You must understand the purpose and implications of encryption before deciding whether to use it.
Encryption locks your data with a password. If you forget that password, the data is lost beyond any chance of recovery. Neither Apple nor anyone else will be able to help you recover that data if you don't know the password.
By the same token, the password must be strong enough to provide the security you want. For example, if you're the potential target of industrial espionage by a government or large corporation, you need the strongest possible password. To create and manage such a password safely is a task in itself, not to be undertaken lightly.
If you're only concerned about casual snooping by someone with no special skill, a weak, easily-remembered password is appropriate.
But regardless of the strength of the password, if you lose it, the data is gone forever.
Another point to remember is that if you encrypt your data on one storage device, you must also encrypt it on all other storage devices that would be accessible to the same attacker. Otherwise the data isn't protected. For example, if you keep your computer and your backup drive in the same room, and the internal drive of the computer is not encrypted, then there's no point in encrypting the backup drive.

If you remove a backup from Time Machine, can you add it later?

if you remove a backup from Time Machine, can you add it back later? I have two backup sets active, but only one is connecting to a drive at the moment. It seems to be pausing TM for the inactive one, which is as I would expect, except that the menu icon for TM shows an exclamation point (= "waiting to backup"). I'd rather have that error / pause sign show if the ACTIVE connected drive is experiencing issues. It has zero diagnostic function as currently set up.
The solution would be to remove the backup drive from the TM list and then add it back later. I am just unsure if I can do this (will TM recognize the alternate backup set again if I re-add it?)
tx

Yes, you can re-add it.

Can i resume a Time Machine backup of an attached external drive (no system, just data) on a different laptop?

I am trying to find out if I can use a Time Machine (specifically on a 2013 Time Capsule) backup of an external drive (only data, no system) attached to a laptop, and then connect that same external drive to another laptop and resume the backup? Or is the Time Machine backup of an attached external drive a laptop "dependant" backup?
Additional info: The laptops in question are 15" MacBook Pro and a 17" MacBook Pro from 2011 running OSX 10.9 (Mavericks)

You are welcome.
I don't think there is a need to start a new discussion unless you want to.
You should have more than one backup of each computer. Hard drives do fail. Time Machine can alternate drives or have a Time Machine and a clone.
The concern arises because i was told that when a wireless Time Machine backup is interrupted the sparsebundle gets sort of "locked" or "damaged", and although the backups can be accessed, no further Time Machine backup is possible. One must that a brand new backup.
Apple support article. Don't let the title bother you. Look at Additional Information, which explains what happens when a backup gets interrupted. I also am including a link for troubleshooting. C3 explains what you can try if the backup is interrupted.

Time Machine formatted itself on my external drive despite pressing "Don't Use"

I have an external hard drive that has been in use on/off for years. I even had backups on it (not using Time Machine). I mounted this hard drive, it was taking a while to mount. A prompt came up to ask if I wanted to use this drive as a time machine backup. I said "Don't Use". It hanged. Meanwhile, I opened disk utility twice. Both I had to force quit. After a while I relaunched finder.
Assuming it would cancel the time machine prompt. Only when did the finder eventually relaunch that the drive mounted to see that all my files where gone and looking in Thermal under ls -a to see their we're spotlight and time machine files along with some oddly named thing. About 1GB Is in use on the drive(I had much more that a gig on it). It is a TB drive
Here is the output from the ls -a on the volume
._.com.apple.timemachine.donotpresent
.com.apple.timemachine.donotpresent
.Spotlight-V100
.fseventsd
.Trashes
USBCˆö?␀.␀€␀
._.Trashes
Anyway would a tool like this (http://www.cgsecurity.org/wiki/TestDisk) help get back my files and format back to what I had previously? Or I am going in the wrong direction? What should I do?
Thanks. If you have any questions please reply below

Thank you Thomas,
I should have mentioned that the drive is formated as FAT32 and I ran verify disk on the drive and this error keep coming up until I stop the process :
"2013-02-16 12:06:23 +0000: / has entries after end of directory
2013-02-16 12:06:23 +0000: Truncate? no
2013-02-16 12:06:23 +0000: Extend? no"
Will the tools mentioned in you post work with FAT 32? I am looking at Data Rescue 3 becuase of the FileIQ functionality since I know I have obsure file formats on there
Does this help or it is irrelevant?

Thinking of using Time Machine. Can you purge the external drive?
