My time machine back up error and now it says it can not read my external hard drive
I have a MacBook Pro Yosemite ...... I was backing up to a WD Elements external hard drive disk and I was in mid back up and everything was going fine..... then an error and when I went back to it ..... it said it no longer can read my disk? What can i do?
A whole lot about Time Machine for help with TM problems. Also you can select Mac Help from the Finder's Help menu and search for "time machine" to locate articles on how to use TM. See also Mac 101- Time Machine.
Use Disk Utility to repair the TM drive. If that doesn't help, and you don't find help from the above, then erase the drive and start a new TM backup.

I'm having some difficulty with Time Machine. It appears to be deleting backups from random dates on my external hard drive. I am not deleting them. Are they hidden and how do I prevent this from happening? Can I retrieve them?
... I didn't know that Time Machine was more a last resort back up instead of main back up.
Don't rely upon Time Machine to the exclusion of all else. I compliment Time Machine with a periodic "clone". TM is much better than nothing, but it's a safety net, not a hammock
Here is my understanding of Time Machine's file deletion algorithm, distilled from Pondini's FAQ, Apple's KB articles, and my own observations.
Time Machine deletes ("thins") files from the backup disk as follows:
Hourly backups over 24 hours old, except the first backup of the day
Daily backups over 30 days old, except the first backup of the week
Older backups get deleted when Time Machine requires space and you deleted them from the source disk.
Therefore, assuming TM has been performing at least one backup per day, backup files will remain available:
at least thirty days, if they existed on your Mac for at least a day
until you run out of space, if they existed on your Mac for at least a week
In addition to the above, Time Machine always keeps one complete copy of your source disk so that the entire volume could be restored if necessary. Any files that remain on your source volume will be present on the TM backup, no matter how old they are.
If you are using 250 GB of space on your source disk, its Time Machine backups are likely to require at least twice that much. A good estimate of the minimum required backup volume size would be about three times the size of your source disk - 1.5 TB in your case.
A more thorough explanation would require Pondini since he has plumbed Time Machine's mysteries far more than I have.

I have given my iMac 2007 model running mountain lion OSX 10.8.3 to a friend and she doesn't have an external hard drive to back up would using iCloud be as good to back up files pictures etc and can I find them again if lost please.
These are the iCloud storage options: http://www.apple.com/icloud/includes/lightbox-storage.html
Also bear in mind that:
1. restoring data over icloud takes time
2. iCloud is not designed as a replacement to Time Machine. -
Hi, have had to uninstall icloud/mobile me from my windows vista pc and now trying to re-install but it's saying I need minimum of windows 7 or 8?

how do you remove back up data from the memory storage? my storage data states that i have over 80gb of data used for back ups and i dont know why as i use a external hard drive as a time machine .now my 250gb flash storage is nearly full.. HELP!
When Time Machine backs up a portable Mac, some of the free space will be used to make local snapshots, which are backup copies of recently deleted files. The space occupied by local snapshots is reported as available by the Finder, and should be considered as such. In the Storage display of System Information, local snapshots are shown as Backups. The snapshots are automatically deleted when they expire or when free space falls below a certain level. You ordinarily don't need to, and should not, delete local snapshots yourself. If you followed bad advice to disable local snapshots by running a shell command, you may have ended up with a lot of data in the Other category. Ask for instructions in that case.
See this support article for some simple ways to free up storage space. -
I had to reformat my OSX 10.5.8 and I can't restore my emails from my time machine backup from an external hard drive - only the latest (post backup) time machine back ups are available to restore. Please can any help? I can find the mail folder in my libraries, but the Restore Button is grayed out
OSX treats the reformatted drive as a different one; it's the same as replacing it, and the old one is no longer connected.
See #E3 in Time Machine - Troubleshooting to see and restore from the "old" drive.
And, you may not want to restore via the Finder; see the blue box in #15 of Time Machine - Frequently Asked Questions. -
I have just added a time machine to my iMac and it is saying it will take 11 days to do the first back up. Any ideas? It is only 355GB but is being backed up wirelessly but 11 days?
Help.Hi lajetidreaming, I'm in the same boat; "See you in 8 days".
As LaPastenague says, use an ethernetcable for the initial backup.
And I will add; Since TimeMachine don't accept any interruptions during the initial backup, make a small backup first. That is - exclude a number of 'secundary' folders like music etc.
When you have one backup completed, TimeMachine is much more forgiving about interrupts, rebooting your Mac and so.
Good luck! -

I can not find my seagate hard drive that contain my time machine back ups how do i do that?
my airport extreme can not locate my seagate hard drive with all my back ups how do i fix this i need to restore some settings?
As Bob says, that's problematical.
If you were backing-up to that drive while it was directly-connected to your Mac, and now want to move it to your Airport, there's an extra problem. See the blue box in #E2 of Time Machine - Troubleshooting.
If you had previously been backing-up to the drive over your network, the backups may be corrupted (that happens rather often, and is the reason it's not recommended). If so, you may be able to repair them, per #A5 in the same article.
Or, you may need to reset the Airport. See Resetting an AirPort Base Station or Time Capsule FAQ. -
I just PAID for Black eyed peas Time of my life and now iTunes says I can't put it on my iPod 5th gen ? What? Why? And how can I get it on my ipod? And if I can't put it on my ipod how do I get my money back? I registered my ipod on iTunes, why was a song I can't put on my ipod even offered to me? What a rip?
Because you can only synce with one iTunes library and you are switching libries by using the new computer. To nake this yyour syncing computer:
- Move all the media(apps, music, synced video and photos etc) to the new computer.
- Connect the iPofd yo the computer and bake a backup fo the iPod by right clicking on the iPod under Devices in iTunes and select Back Up
- Restore the iPod from that backup.
Note that the backup that iTunes makes doe not include media.
To move mdia to the new computer see:

I recently had the genius bar change my imac hard drive because it crashed. For some reason Time Machine didn't back up some of my important files. Can I get my damaged hard drive back from the genius bar to see if I can access that info?
Unfortunately, that drive is long gone, probably back to the mfr. Drives are not returned when they are exchanged. You can go by and ask them, but the chances are slim to none.

I have just started using Time Machine. I was thinking about deleting old E-Mails on my Mac to clean. Does Time Machine back up the E-Mails , if so how can I find them in Time Machine ??
If you back up your mac before deleting your emails, Time Machine should back up your e-mails.
I never tried this so i'm not sure to find them in Time Machine. To browse in your backups simply click the Time Machine icon in your dock. In the right bar, you can select an backup. Than you can browse in finder, in your backkup.
EDIT: Just browsed and CT above was right. This topic might help you:

Since time machine backed up my computer does that mean I can delete files so I can increase storage space on my hard drive?
NO!
Time Machine is not an Archival Backup. It will keep files for a while, but if it needs the space, it will delete files that no longer exist on the hard drive.
Get a couple external drives and move the files to both of them. -

If I already have an Airport Express Base Station, can i hook an external hard drive into it's USB port and use that hard drive with Time Machine?
No, and that shouldn't be done with an AirPort Extreme or Time Capsule.
