OS X Mountain Lion :: Reformat Hard Disk Drive To Be Compatible With Time Machine?

Jun 5, 2014

I have a question which I am quite unsure. I am shopping for a HDD drive (Western Digital My Book 3 TB) and was told that it cannot be reformatted to be compatible with TIme Machine.

I would like to verify if it is true.

OS X Mountain Lion :: Restore Failed External HD To New Hard Drive From Time Machine?

Sep 11, 2014

Since the harddrive of my IMac was full, I added an external harddrive to the system for my photos. I use another external harddrive for time machine back-ups (backing up both the IMac and external harddrive with my iPhoto libraries). Recently the EHD with my photo libraries crashed. I now want to restore it from time machine onto a new external harddrive, but am not quite sure how to do this.

OS X Mountain Lion :: Time Machine Won't Exclude Hard Drive From Backup / Grayed Out

Jun 23, 2014

I am backing up my data from my mac book pro for a second time. I plug in my external, and it says it doesn't have enough memory to back up my computer. I have 1 TB hard drive and used about 650 MB for the first back-up. Obviously I don't have enough to back up everything for a second time. I just want to back up the new stuff. When I go to exclude the current external from the new back up, it's grayed out. Do I have to delete the contents of the hard drive and re-back up the entire computer?

OS X :: Reformat External Hard Drive For Time Machine Methods?

Mar 29, 2009

I have a Western Digital 500gig external hard drive (model wd5000c032) which I'd like to completely reformat to use with my macbook pro and Time Machine (running os 10).As it is now, my mac can only use 147 gigs, and often gives an error message saying it needs additional space to backup. It was previously used on a pc to hold pictures, but I doubt it used anything near 357 gigs for that.

MacBook Pro :: How To Reformat An External Hard Drive After Time Machine

Feb 18, 2012

I have an external hard drive upon which I put movie files that I view through a Sony box (like the Roku box). I brought my MacBook in for a repair and connected the same external HD and used Time Machine to make a back up. It did reformat it in order to do so, but since the Sony box isn't a pc or mac I didn't think it would make a difference, but now the Sony box won't recognize HD. Is there a way to reformat it on my MacBook so that I can use it on the Sony box again, or do I need to reformat it with a Windows computer? I had no issues when transferring files only and using the Sony box.

OS X Mountain Lion :: Time Machine From Two Macs On To One Disk

Jun 20, 2014

We have two Macs. I use my Mac for work and Time Machine to keep a backup of my Mac every hour. Occasionally (every few months) I'll unplug the external hard-disk from my Mac and use Time Machine to backup my wife's Mac. Hence, two Macs, both using the same hard-drive to backup to.  Recently there is only the space on the disk for Time Machine to keep backups of my Mac from the previous day.

Is there a way to delete backups of my wife's Mac to give my backups more space? Can I simply open the back up disk and delete a few of the backups of my wife's computer? or do I need to do something more complicated like partition the disk? or is there a way to tell Time Machine to keep more of my backups and less of my wife's?

OS X Mountain Lion :: Time Machine Backup Disk Not Available Over WAN?

Aug 25, 2014

I have port forwarded port 46 (TCP and UDP) to port 548 a Mac mini server running Mac OS X 10.6.8, and I have Time Machine backup disk on it set as a share point with Time Machine support enabled. On my Mac Pro running OS X 10.8.5, I am able to connect via AFP to my server with the address "afp://my-ip-address:46" and can read and write on the backup disk share point. I tested that, and it works. When I am on the same LAN as the server, I can use that disk for Time Machine and have been doing so for years. However, I cannot do a Time Machine backup to that share point over the WAN. When I open Time Machine preferences, I can select the share point as my backup disk, but once I start the backup, it says "Backup disk not available" and fails to start.

In case you're wondering, I forward port 46 to port 548 instead of port 548 to port 548 to minimize hacking attempts. Last time I used a default port, a computer in Taiwan started spamming SSH authentication failures.

OS X Mountain Lion :: Time Machine Won't Back Up OWC External Drive

Aug 22, 2014

Mac Mini running 10.8.5.  Time Machine will not back up brand new OWC MiniStack external HD. I've trashed TM prefs, reformatted the TM drive, verified that there are no exclusions, but it won't back up the external HD which contains only data files -- no system, no applications.  TM does back up the internal HD.

OS X Mountain Lion :: External Drive Using For Time Machine Won't Eject?

Aug 31, 2014

I was using an external drive for Time Machine for the past year and a few months On Saturday a message came up that it failed.  I tried initiating the Time Machine again but failed. I decided to get a new bigger external drive to use for Time Machine. When trying to eject the external drive I was using it gives me this message:

Would it be safe just to force eject or log out and then log back in again to eject it so I can use my new external drive?

OS X Mountain Lion :: Can't Copy Time Machine Backup To New Drive

Jun 25, 2014

I can't copy a Time Machine backup file (Backups.backupb) from one external hard drive to another. Both hard drives are Seagate 1TB Backup Plus. The Backups.backupb file is about 275GB. When I try to drag and drop the Backups.backupb file from one drive to the other (which I've tried three times) it to begins copy but after about 3GBs are copied I get a message that says "The operation can’t be completed because an unexpected error occurred (error code -50)." 

I formatted (erased) the new hard drive with Disk Utility as Mac OS Extended (Journaled). Apple Support says I should format the new drive in Mac OS Extended (Journaled) "with a GUID partition," but I don't see the GUID partition as an option when I format the drive. Is this necessary, and if so, how do it do it? I'm using OS 10.8.6 on a 2012 MacBook Pro retna. 

I also tried copying the backup files to another drive (a Maxtor HD) and got the same error message.

OS X V10.7 Lion :: Disk Drive May Not Support Time Machine Backup Over Network

Mar 28, 2012

Is time machine already/still supported on current OSX 10.7, or is it already deprecated as it was introduced several releases ago?When I try to activate Time Machine on my all new OS X Server, I get a dialog "Choose destination volume for client Time Machine backups:". I choose a volume, and the message is displayed "This disk drive may not support Time Machine backup over the network. Get more information about compatible drives."

"More information" links to [URL] which just provides commonplace advice to not disconnect drives while the drive is in operation. The support article is marked as archived and no longer updated after 10.5. The promised information is not provided.Is there anything obviously wrong with the setup?

Mac Mini Server, OS X Lion 10.7.3, 2x750 internal disks as RAID1, new of this month

The external drive is also used as Time Machine for the Server's local volume.I have read recommendations to use separate partitions per client, for time machine solutions using a third party NAS. Instead I chose the original - am I wrong to assume that the OS X Server's Time Machine service is able to manage multiple clients?

OS X V10.7 Lion :: Back Up With Time Machine To A Previously Used Hard Drive?

Feb 24, 2012

I've just replaced an old MacBook Pro with a new one and used Time Machine to get the new MBP set up.  All is well and it looks like my new computer is a mirror of the old (tested for a week now).  If I turn on Time Machine with the new MBP using the same hardrive as the former, will the files remain and be accessible? Presently, I can only access the old files by going into the hard drive through Finder and even then, most are locked.

OS X V10.7 Lion :: Time Machine - Auto-backups To Hard Drive?

Mar 28, 2012

Time Machine is not working correctly since installing Lion. I found (from using Adobe Bridge) that there seem to be automatic back ups being made 20 times a day and onto my hard drive!  Usually I back up to an external drive specifically for back up using Time Machine. Now time machine takes several hours to back up when I have that disk wired in (with USB) and the Time Machine icon in the Apple menu is always showing that the back up is delayed.

I am trying to get Time Machine to backup my external hard drive. I have the external drive formated as Mac OS Extended (journaled) and I have also removed the drive from the Excluded list.I put some 'test' files on the external drive and told TM to do a backup and when it is finished the only way I can see my external hard drive in TM is if it is connected to the computer. It doesn't seem to be backed up anywhere in TM that I can see.

OS X V10.7 Lion :: Why Doesn't Time Machine See Entire Hard Drive

I have a 500 GB external drive that uses FireWire.  Recently Time Machine started deleting several backups to make room for new ones.  It now says the oldest backup is May 4th, 2012.  I thought this sounded like a problem.  When I looked into the details, my iMac now thinks my hard drive has 400GB instead of 500GB.

OS X Mountain Lion :: Time Machine Can't Complete Backup To Time Capsule

Jun 19, 2014

MacBook Pro mid-2012, 8GB RAM, 750GB hard drive, Mac OS X 10.8.5

One Time Capsule at home

One Time Capsule in vacation home 

MBP backs up everything on internal hard drive to Time Capsule at home, where we live during summer and spring. When moving to vacation home in fall and winter, MBP backs up everything to Time Capsule in vacation home. 

During the 6 months at each residence, the backups work great to the Time Capsule at that particular house. However, after some time (maybe a week?), Time Machine displays an error in Notification Center: "Time Machine can't complete backup to Home Time Capsule" (when in vacation home) or "Time Machine can't complete backup to Vacation Time Capsule" (when at home). 

It's obvious that this occurs because Time Machine was set to back up to 2 Time Capsules and expects both of them to be reachable. Is there a way to suppress these Time Machine errors for the time that we're away from one of the Time Capsules?
