Can both the old(migrated from another external HD) and new time machine backup be read on iMac?
HI,
I lately migrated the time machine backup from an external HD(WB) to a new one(G Drive). If I connect the new one i.e. G Drive to my iMac for Time Machine, will there be a new folder created in G Drive? Will it be a new backup i.e. backup everything on iMac? Can the old time machine backup be read when I enter Time Machine on my iMac? Thanks in advance.
Hi, best info I can find on it is here...

How do I set up external storage and a Time Machine backup?
I am trying to organize my external storage for a new iMac with an 500G SSD drive. I have a new thunderbolt G-Raid drive and an aging Airport Time Capsule. I was thinking of storing music and pictures, as well as a Time Machine backup of the SSD, and storing a Time Machine backup of my music and pictures on the Time Capsule. Is this reasonable? Will I need to partition the G-Raid? Are there any special issues of which I should be aware?
Although it's getting a bit dated since the owner passed away this site given to us by the late, great Pondini will answer all of your questions about Time Machine and more http://pondini.org/TM/Home.html

How to backup external hard drive to another external hard drive using time machine ?
Hello,
i have an external hard drive which i store all my drum samples and sound library on and files are contantly changing, adding new sounds, deleting old ones etc ..
So my method of back up as of now is to just copy all the edited files and click and drag to the back up disk.
Now, my question is, how do i back up my external hard drive to another external hard drive using time machine ? I read somewhere that you can do this, i cant find the post however. It would be nice to automate the back up process rather than manually finding the files to copy over.
Thanks in advance !The question you pose is conditional, in that you should have more than an exact
capacity replacement for a clone, if the drive you are going from (or one going to)
has insufficient free space and that has a bootable clone on the drive; any space
tied up in a partition for Time Machine backup, takes away from the running space
if you should need to run the computer from a clone on the external HDD's other
partition.... Better to have a good capacity of additional reserve unused free space.
Be sure any clone copy that you hope to use as a re-close, that each in turn is tested
after a clone operation. Also consider using each running system's Disk utility and
have First Aid 'repair disk permissions'. Preparation of a new drive or even an old
drive that may have questionable artifacts or errors on it, should be reformatted. To
even go as far as Secure Erase (overwrite) at least one-pass before reformatting it
again, could help.
However, I'm not sure if the drives and situation you are looking at would necessarily
be a good match. It could work, but you'd need a reasonable size partition or hard
disk drive for a system. Snow Leopard and all its associated applications, can do
OK in a 100GB HDD. (My computers have more storage capacity than is used; so
for mine to have 60% free space, is good.) Virtual Memory is drive space used by
OS X, that can be a substantial amount for swap and temp files. Some applications
make duplicates of works-in-progress, for each change in an open file; that adds up.
{This question (& my reply) should've been in their own thread & not at the end
of one that is nearly three months old, + marked 'solved' by the original poster.}
So I guess I don't have a direct answer to your question; having just returned from
a few hundred miles and automobile issues, too. I'm not really thinking on-topic...
The clone should be on its own separate drive, and up to 3TB drive dedicated to
Time Machine may be overkill, however that software will consume old backups first
when it uses up all the space. Or usually that is what happens in TM backups. If
that isn't happening, there may an issue in how Time Machine is set up.
Good luck & happy computing! -
You can't open the application "QuickBooks Application" because it is in a Time Machine backup.
How I can restore QuickBooks aplication and back-up data from my time machine.
I did read all the info supply in the previous link already, and it let me know how to restore files no aplication. I tried to do it as they explained w/o any success. I still get the message:"You can’t open the application “QuickBooks Application” because it is in a Time Machine backup."

How can I edit my website from another computer? and how can I create a new website next to the one, I already have? Can anyone help, please?
Move the domain.sites file from one computer to the other.
The file is located under User/Library/Application Support/iWeb/domain.sites. Move this file to the same location on the other computer and double click and iWeb will open it. Remember, it is your User Library that you want and not your System Library, as you will not find iWeb there.
Just create a new site on the same domain file and it will appear below the other site. If you want them side by side then duplicate your domain file and have one site per a domain file and they can then be side by side. -
I have a mid2009 MacBook Pro running Mavericks for which I have been using a USB WD HD for Time Machine. I'd like to get a wireless HD and start a new Time Machine backup for this Mac and retire the 5 year old WD drive. Can I start over?
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.
See the + and - of all data backup/ archives below and "spread it around".... or the "dont put your eggs all in one basket" philosophy.

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. -
Hi, I hope this question won't seem too basic but if I want to use a new larger external drive for my time machine backups, will it do a new full backup the first time I plug it in and if so, do I really need all the old backups on my smaller external drive?

Yes, it will do a full backup.
and if so, do I really need all the old backups on my smaller external drive?
Only if you want to be able to go back in time to those previous Time Machine backups. When you plug in the new larger external drive, you will only be able to go back as far as the first day you plugged it in and ran the first Time Machine backup on it. -
Due to NAS issues, when I started a new time machine backup it did not have the old backups available. My question is do I need to delete them or will time machine automatically reclaim the space? There is only one sparse bundle but when I enter time machine I don't see my historic backups. I use a synology DS212 for my time machine. Started a new backup which is 218gb but it says 618 gb is occupied therefore it looks like 2 or 3 backups are still on the disk. Before my NAS issues the last backup was in 2014. As you can see there is a second sparse bundle from 2012. Not sure what that is.
This is an old message now, but what happened to me similarly was:
I had a major computer crash and through complicated pathways ended up reinstalling (Mavericks) as a new user (long story).
At least I had good Time Machine backups on an NAS drive (Synology DS212j), or so I thought - when I started Time Machine up again, the old backup file was gone, replaced by a new one using my "new computer" name. The old file was gone both by directly mounting the NAS drive and by clicking "Enter Time Machine".
It's like I had {OldShareName}.sparsebundle and then it was replaced by {NewShareName}.sparsebundle, all of the old info vanished.
(I have spent a week finding old files elsewhere and have completed a satisfactory self-restore. It pays to "archive" [my own variation of] as well as "back-up".)
My belief is that if this were a wired-netword-drive, e.g. plugged right into my iMac with a USB cable, then the old file would have remained.
But this is an NAS drive, connected directly to my Airport wireless router, and I don't know the significance of the fact that it stores its Time Machine backups as "sparsebundle" files rather than simply as plain(er) files.
As usual when things get complicated with computers (not just Apple computers) there was never a warning message. Something like "YOU'RE ABOUT TO DELETE A TIME MACHINE BACK-UP FILE!!!" would have made my life a lot simpler.
BTW, I did try a "restore from Time Machine" option the first thing I had my "new computer" (old hardware, 2009 iMac) up and running, using Migration Assistant, and it ran for many hours and then failed in the wee hours - what that has to do with anything I'm not sure.
I'm not sure that I have a question about this other than "why do these things happen to me?", but it's a warning. Apart from that I've been very happy with the stability and reliability (but not the cost or set-up complexity) of NAS vs. directly-cabled external drives.

Can I use a single external drive to maintain time machine backups for two Mac computers?
Hello
We have an older mac mini and macbook air. I have one Western Digital external USB drive. Can I use the same drive to hold and maintain time machine backups for both machines?
I already have the macbook air time-machined on the WD drive. I now want to backup the mac mini onto the same drive. Is it going to over write the time machine backup or is the software smart enough to maintain two separate files, partitions, whatever it does..?It will maintain separate backups. Note that it's generally advisable to use separate drives for best practice backup, but yes, it will work for both computers, provided you have enough space (need generally 2-3 times the total used file space for both Macs).

HT201250 new external hard drive for Time Machine backup suggestions?
Ok, I have 3 external hard drives; unfortunately I've used them on my PC and they are read only on my iMac. So, I need to buy a new external hard drive for Time Machine backup. I'm a little confused; can I buy any EHD and them format it so Mac can use it or are there special EHD's I need to purchase?
Anyone have a particular EHD that is working well for you? Thanks, BlueBluehowler wrote:

Unless you need all three external drives for your PC, you can reformat in one of them in Mac OS Extended (Journaled) for use with Time Machine. However, since Time Machine backs up hourly, you'd need the external drive to be running constantly. That means ventilation of the drive becomes an issue since some, such as Seagate, can get very hot in their sealed enclosures. Some drive manufacturers try to get around this by spinning down the drive when not in use, but I've read complaints that that doesn't play well with a Mac. So whether you reuse one of your current externals or get a new one, it's a good idea to keep the drive's ventilation in mind. -
Is it possible to use an external hard drive for time machine backup and also as a regular hard drive?
I am using an external drive in the exact way that you described. You just keep it plugged in to the computer when you want to access the movies and files. In order to put files on it, just go to finder open up the drive under devices and drag and drop files onto the drive. It is just like using a usb drive with a terabyte of space.

I have an external HD that I've been using exclusively for Time Machine backups. I need to clear space on my hard drive, so I was thinking to move music & photos to an external drive. Wondering if I can use the same one I have (which I'll aslo keep using for Time Machine) or if I need to get another drive.
Hi Jossydtaylor,
Time Machine can use either an entire external disk or a partition of that disk:
OS X Mountain Lion: Disks you can use with Time Machine
http://support.apple.com/kb/PH11171
You can use Time Machine with a Time Capsule, and with USB, FireWire, and Thunderbolt disks. The backup disk can be directly connected to your computer or be on a network. If the backup disk has been divided into partitions, you can use one of the partitions.
If the disk is partitioned using the Master Boot Record (MBR) partition type, some partitions may not be available for use with Time Machine. The GUID Partition Table (GPT) partition type is recommended.
For more info on partitioning, see this article:
Disk Utility 12.x: Partition a disk

Cheers!

My time machine backup disc, which has been working ok for a couple of years has suddenly disappeared from the desktop. The time machine program tels me it is unavailable. I have checked that the drive is working by booting up in Windows. and Windows can see it and read it ok. What has gone wrong, and how can I fix it?
I have tried unplugging it and reconnecting, but it is still apparently not seen by the system.
I could use Windows to reformat it, and start again, but this would loose all my previous backups, and I've no guarantee that the system would notice it even then.
Has anyone any ideas?I think it's formatted on FAT 32 system, but I'm not sure. It's been working for a couple of years so far without any problems, so I think it must be compatible with Mac. The problem is that all of a sudden, the Mac doesn't acknowledge that it is present.

Can i include external usb drives in Time Machine backups
Can I include external usb drives and sticks in Time Machine backups?
This was the question I searched a week for. My machine is a MBAir with Yosemite. I have a bunch of USB HD and sticks. This is a sharing of what it took to solve. I lost a couple of important document revisions lately because of not having differential backups on them, so wanted to include them in Time Machine.
Yes it can, I found. But it's a wee bit backwards. And apparent inconsistencies drive you crazy. Time Machine is supposed to do this by default, and wants you to tell it what NOT to include. Trouble is, formats create many troubles.
But the USB sticks and HD's you buy are PC formatted. And you'd like to share, as the Apple does with FAT16, FAT32, and exFAT (to overcome the 4G size limit on the others). Even NTFS can be plugged in and be read-only. Turns out you just can't incorporate into TM backups.
Open Time Machine Options, and look at the drives listed in the exclusion window. Drives that you know to be plugged in and registered by Finder, may or not be registered in the exclusion window, and if registered and their icons may be bright or dimmed. Bright will NOT be included. Dimmed are excluded. Normally the operation is to use the or to exclude these drives from your next BU operation. (this instruction is lost the next time in manual mode). So if a drive or stick is shown and is bright it WON'T be backed up. If you it from the window, then it will grey out and WILL be backed up. If it's not there to offer you exclusion, you can browse to such a file or device so you can exclude it. TM's exclusion window will show the PC formats: FAT16, FAT32, and exFAT greyed out (as not included). NTFS is bright looking like it might work, but when doesn't dim, it disappears, and is ignored in the actual BU.
Sources are supposed to be included in the backup if it isn't shown bright in the exclusion window. In this respect I only use TM manually, and not for programmed BU's, so I cannot speak to that.
If everything you have is formatted for the Apple disc system (Mac OS Extended) then there are no contradictions or partial equivalences. The mounted disc or stick will show in TM exclusions window, and if you it, you'll see it in the Time Machine pile of calendared directories, with all the files. And of course it will do the differential backups for it that we use TM for in the first place. Just remember to prepare the BU by not excluding.
BUT NOW THE VARIABLES. It now depends upon the formats. I use the Paragon NTFS program to permit writing NTFS. (Apple can normally read but not write NTFS). Paragon is lovely because for normal computer use, I can read and write both Apple and PC files and disc formats in Finder (for 3 years now). But Time Machine cannot be reached by Paragon so it's NTFS behaviors are outrageous. Paragon reaches Disk Doctor so you can read, write, format and heal both Apple and PC formats. And this really confused things respecting Time Machine. I literally worked through every variable, from stick to disc to prove what did work, and when false appearances of working showed up.
Respecting that very Time Machine display of Finder windows piled backwards through time there's a confusing bug. When first opened, TM shows NOW as the current setup and works just like a Finder window in present time. And the outboard discs and sticks show as in Finder. BUT working back in time, the left window DOES NOT SHOW THE CONDITIONS AT BACKUP but rather in all left windows shows the present setup. So you need to work from the right hand side dates and times to go back and see when you had that stick or HD plugged in. And then, finally, you will see the files you wanted saved. But if there is a stick on the left than TM doesn't like but Finder likes you'll see it left but nothing will be in the files. Clicking on the pretender just jumps to the root.
My Disk Doctor provisions (with Paragon) show, Mac OS Extended (Journaled), Mac OS Extended (Case Sensitive Journaled), MS-DOS (FAT), exFAT, Windows NT Filesystem, Windows NT Filesystem (compressed). It's a better utility than in Microsoft and I use it for such maintenance.
Bottom line, I like TM very much. 2 years ago I lost my air and TM was able to reconstruct my machine many times in the course of the troubleshooting - all the way from the start to the last without ever missing a beat or a file. So I accept this limitation and make copies to another HD formatted in NTFS when I work on PCs.
Hope's this sorts out being lost in the desert for a few of you.
