My external drive is not showing up on my time machine backup.

I have two external drives, one for Time Machine and one for some of my media. I've setup time machine to backup both my internal drive and my external media drive; however, when I enter time machine I do not see the backups for the external drive. Am I doing something wrong? I have TM routed to back up both the external media drive and the internal drive, but it just doesn't turn-up in backups. There's enough space on the disks. Thanks.

Maybe this will help.

User not showing after restoring from time machine backup

I was having issues with my 2009 Macbook pro. took it to the Genius Bar. Diagnosistics all showed ok. (I had done troubleshooting before I had the appointment). They suggested wipe and reinstalll from my time machine backup. I agreed.
Returned home to do the reinstall. When I went to log in found that one of my user accounts did not show in the log in - only my main and "guest" accounts. On checking the "users" folder the user is present. It also does not show in the system preferences user screen but when I try to recreate it says it exists. Note I have done this wipe and reinstall with Mavericks
Help! Most of the content I have on my main BUT there are several things that are not.
Thank you for your attention.

Issue solved with visit to Genius Bar.
As I understand it here are the steps the Genius did. Attempt to create the account (system preferences->users) with the same information. It will say it already exists. Very carefully read the options. One will say use the existing account. BE CAREFUL because one option will wipe your data.
If you need to do this it might be worth the trip to the Genius Bar as you could wipe your data. One precaution I took was to bring a full copy of that user account onto my desktop (from the backup immediately before the wipe) in addition to the one in the user folder. Once we verified that the account was working I moved the desktop copy to the trash and again verified the account (just to be safe).
Hope this helps someone else.

My external drive is not showing on my desktop

My external drive is not showing on my finder and it is turned on and connected by firewire. Is there an alternate way to force my G5 to see the external drive?
Laura

Check the settings in the General and Sidebar tabs of the Finder's preferences. If those are set properly, open the Disk Utility in the /Applications/Utilities/ folder and try mounting and/or repairing the drive.

External drive does not show up in finder/ disk utility not able to repair

Hello,
My external drive does not show up in finder. But it appaers in DISK UTILITY. When I tried to repair it, it said:
Verify and Repair volume “ANNE HD”
** /dev/disk1s1 (NO WRITE)
** Phase 1 - Preparing FAT
** Phase 2 - Checking Directories
Unable to read directory (Input/output error)
Volume repair complete.Updating boot support partitions for the volume as required.Error: Disk Utility can’t repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed-up files.
How can I back up files if the external drive is not found in FINDER? I tried to restore with disk utility, but it doesn't seem to be able to select the hard drive.
Can you please help me?

Thanks a lot Niel,
Diskwarrior is a program for what you need to buy a DVD. I live in Brazil I have no idea where to buy it. Or can you download it?

Lacie Rugged external drive will not show up after Yosemite update.

Lacie Rugged external drive will not show up after Yosemite update. It show up in disc utility I can't access it.

I have the exact same issue. Have you had any luck with a solution?

External drive does not show up in Time Machine

I just applied the lastest update today and now my external drive does not show up in Time Machine. It does show up in Finder.

Gracias Sir Kappy, These instructions didn't include Yosemite, but I followed the closest and used Mavericks instructions and the command-R was the key, which I suppose means 'restore?' Nothing is explained as we should all be able to read the programmers minds by now...
Thanks for the help and problem resolved.

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.

My backup hard drive does not have enough space for time machine to perform a back up even after erasing entire contents of bu hard drive

My backup hard drive does not have enough space for time machine to perform a back up even after erasing entire contents of bu hard drive. The hard drive has been in service for almost two years performing this function with no sign of failure. How do I adjust time machine perameters?

The only way to limit the size of the backup is to exclude data from the backup, which you can do in Time Machine preferences.
If you use multiple browsers, have you tried clearing your browser caches? However, that's just a stop gap if it works. You either need to limit what you backup or get another drive.

Can external drive connected to TC be used for Time Machine?

My 1 TB TC is running out of space and I can't afford the 2TB version. It's much cheaper to buy a 2 TB drive and plug it into the USB port on the TC, but before I do so, can someone savvy tell me if I will be able to select the drive connected to the TC as a Time Machine backup drive?

Thank you for this answer, and for that very helpful link. I can see that the Archive feature will not be practical for everyday backups,
Right.
so I'll have to find another solution...
See Kappy's post on Basic Backup, complete with links to the web sites of each product. You might also want to investigate Chrnosync: I've seen some posts that it can back up a network drive, but don't know if that's true.
Basically, if you run out of space on the TC's internal drive and decide to repurpose it for storing data, you have to be OK with not having that data backed up. I don't get this decision on the part of Apple—maybe they want me to shell out $400+ for a new 2TB TC?
Doubtful. Backing-up network drives, especially to another network drive, would be even slower and less reliable, and not something most Mac users would want to do. And even if you got a 2 TB, Time Machine still couldn't back up a network drive.
And they won't let you use a hard drive connected to Airport Extreme for TM backups either, which I'm guessing is another ploy to pry more dollars from our hands.
Now, don't be paranoid! They don't prevent it, but they don't support it, either. Some of us do it anyway, but it's generally not especially reliable, so we make sure to always have secondary backups. Nobody here can say why they don't support it, but unreliability sounds like a pretty good reason.

The file could not be saved in folder "Time Machine Backups"

I've tried to setup TM with several external drives (USB and Firewire) and I get the same results... the file "xxx" could not be saved in folder "Time Machine Backups". Any ideas?

Hi, and welcome to the forums.
If that's exactly what the message says, it's a new one. If it's actually "An error occurred while copying files to the backup volume" or "Aborting backup because indexing a file failed," see #C3 in Time Machine - Troubleshooting (or use the link in *User Tips* at the top of this forum).
If not, see #A1 there for a handy widget that shows the backup messages from your logs. Download and install it, then copy and post all the messages for one backup attempt here.

Backup to External Via Airport, not listed as available in Time Machine.

I would very much like to set up a time machine backup using my external hard drive. I don't have time capsule, but I have airport connected to an external hard drive. Also, I would prefer that time machine only keep tabs on one folder, the Documents folder. My documents are all that I need backed-up, not a lot of space required, but vital info that I hate having to backup everyday. Nothing else needs a daily backup. Is there a way to do this?
Thanks for the help!

Time Machine backups to AirDisks (e.g. USB HDD attached to Extreme) is unsupported, but has been successful by some. As well, once you decide to move your TM backups to an AirDisk, you cannot continue backing up to your previous TM backup. The format it saves to vs. a local HDD is different. The folder structure you see becomes a sparsebundle/disk image via the AirDisk.

[http://jamesshore.com/Blog/How-to-Accelerate-Time-Machine.html]
For excluding everything but your documents, open TM Preferences -> Options. Try to Select All, then deselect the folder you want to backup. Note that you will NOT be able to restore your Mac to its current state in the event of an internal HDD failure. Just your Document folder is backed up.

HT4848 Is it possible to partition an external hard drive that is already being used for Time Machine backups without it being erased?

I'm want to use my current external hard drive, which I use for Time Machine Backup, as a recovery disk for Mac OS X Mountain Lion 10.8.2. From what I have read, the recovery disk assistant will erase all data on the external drive unless it is partitioned. Can I partition my current backup drive without erasing it, even though it is already being used for Time Machine?

It's very simple to test. Turn off your computer. Have your time machine backup plugged in. Hold option and turn it on, keeping option held. Do you see your time machine drive? If so, select it and press enter. You'll end up in recovery. If it works, there you go. Then just click the apple and restart to get back to your regular desktop. Then you'll know for when you're ready to do the deed.
Edit...
I'm not sure if time machine will think it's an entirely different computer, though, when a hard drive changed, making an actual restore not doable. Either way, you could still reinstall mt lion fresh and then just migrate after, skipping the need for SL.
