Backup on External HD

I have to say I've never done backups before, but I'm about to go from Panther to Tiger and want to prepare by doing proper backups for both my iBook and iMac. This is a very basic question. I just purchased an Iomega 300GB external HD. If I backup my iMac G4 to it (I mean actually backup the entire HD using Retrospect or Super Duper), is the drive then unusable for dropping files on it - say copies of my iPhoto libraries, my documents file, etc. Can I backup both the iBook and the iMac on the same external drive?

Hi Jim,
it all depends what kind of external hard disk you bought. If you bought a firewire drive you can do everything you need. If you bought a USB drive then you are out of luck since USB is not a bootable interface with MacOS X on PPC-based computers.
If you want to create bootable clones of both of your computers you will have to partition the backup drive. Personally I use Carbon Copy Cloner for these backups.
And yes, of course you can drag&drop files to that drive as you would do with any other hard disk.
If this answered your question please consider granting some stars: Why reward points?

I have my iTunes library on an external HD because it is too big for my iMAC 500GB HD. I want to backup my external HD. Can I do this with any Apple cloud product or should I look elsewhere? Also is it worth just buying another external HD to back up

I have my iTunes library on an external HD because it is too big for my iMAC 500GB HD. However, it is not backed up, so I need a solution to backup my external HD. Can I do this with any Apple cloud product or should I look elsewhere for cloud products? Will it be cheaper/easier just to buy another external HD to back up my existing external HD? Thanks

I don't know if this is me adding files to iTunes when the external wasn't connected
it is.
is it OK to just keep deleting that library on the Air?
i wouldn't - at least not until i
mount the external
point iTunes media folder location back to the external via preferences > advanced
consolidate my library via file > library > organize library
The ntfs hasn't seem to be causing any problems, but I've always wanted to know.
in order for your Mac to write to NTFS drives, it needs some help by installing e.g. the NTFS 3G driver. apparently that or something similar is installed on your Mac already. preferably, it would be formatted for Mac but then windows machines would need to have e.g. MacDrive installed to recognize the drive.

Time Machine backup on external drive no longer working after upgrade to Yosemite

Can anyone explain why, after upgrade to Yosemite, Time Machine is no loger working? Backup on external drive stops few seconds after it has started. What can I do?

Welcome to Apple Support Communities
Try running a DVD Lens Cleaner disc through it, a little bit of dust or dirt is all it takes to throw them out and it might just be co-incidental with the upgrade.

Can time capsule backup an external hard drive

Trying to backup an external hard drive to time capsule, through time machine. Possible?
My drive is greyed out in the Time Machine exclude options.

Yes, when the drive is formatted as Mac OS Extended (Journaled) or if other means are used to back the drive's contents up.

How can I take backup in External HardDrive and then reinstall new OS and then restore data from External Hard Drive

I have goot some issue with my Macbook i7, I am not able to start my Macboook its keep showing the Grey screen after login.
I have done something where I have successully taken the OS backup on External Hardrive which was saying computer will start automatically. After this I founded a Fresh new computer but may be that was running on External hard drive.
I am **** confuse what should I do next?
Anyhelp wold be great......

Delete the user account, then use the "Erase Free Space" option in the Erase tab of Disk Utility to write zeroes to the drive. Stick with the "Fastest" method (one pass of zeroes) unless you're hiding secrets from the NSA - anything more stringent is a waste of time.

I am out of space on my Macbook Air and have a Time Machine Backup. I want to complete reset my mac, but wonder if I can pick and choose what I restore to my computer? Can I also use my time machine backup and external storage as well?

I am out of space on my Macbook Air and have a Time Machine Backup. I want to complete reset my mac, but wonder if I can pick and choose what I restore to my computer? Can I also use my time machine backup as external storage as well for the files I don't need everyday?

If you are using "Restore from Time Machine Backup" option from OS X Recovery, you can only choose from the broad categories presented.
... Can I also use my time machine backup as external storage as well for the files I don't need everyday?
To be clear, if you are asking if you can use the volume containing your Time Machine backup to store additional, non-Time Machine files, the short answer is yes.
It's not a good idea though, since the Time Machine backup will eventually fill all available space, after which it begins to remove old, "expired" backups to make room for newer ones. The presence of additional files doesn't change that fact, and Time Machine will not erase them, but you will encounter a dilemma should you want to store additional files on that volume when there is no remaining space. You will have to make room for them on your own, by deleting existing files. Furthermore, since Time Machine cannot back up its own volume, those additional files will not be backed up by Time Machine.
The easy solution for what you describe is to purchase additional external storage. External USB hard disk drives have become very inexpensive; about $55 will buy a perfectly suitable 1 TB drive.
You can also choose to replace your MacBook Air's internal storage with a larger capacity one. Look for a suitable replacement from OWC / MacSales:

That gets a little more expensive but it is the optimum solution.

Using Time Machine to Backup an External Drive (RAID 1)

Is it possible to backup an external drive to another external drive using Time Machine in Mountain Lion?
The following diagram describes what I want to do. I am basically trying to use Time Machine as an external RAID 1 system. However, I don't want to buy a RAID 1 box. I want to have control of TWO OR MORE time machine setups. I don't want to backup my OS every time. I simply want to backup one external drive to another external drive. The drives are 2TB each, so the advice to buy a big hard drive to back everything up on won't work. Also, I am often swapping drives and would like to use this system for all of my projects and all of my drives. Any help would be great. Thanks for your time.
NOTE: I am on Lion and wanted to know if this was possible before upgrading.

To be clear, TM can back up your external drive perfectly well, provided it's in MacOS format. What it can't do is back up the external drive alone to one destination, and everything else to a different destination.
As for what you should use instead of TM, I don't really have an opinion. SuperDuper and Carbon Copy Cloner are well regarded. You need to make some decisions about backup strategy before you choose a backup method. TM makes incremental backups, so you can revert to any of several earlier versions of a file. Those third-party products can do that too, though not as efficiently as TM. Also bear in my mind that a single backup is inadequate. You need more than one backup to be safe, and to be truly safe, at least one backup must be stored off-site at all times.

How can I backup an external hard drive using Time Machine?

How can I backup an external hard drive connected to my MacBook Pro using Time Machine?

Attach drive, open Time Machine preferences, be sure external drive is not in the Exclude list.

Time Machine won't backup my external hard drive.

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. Please Help
Thanks.

My computer was totally destroyed & I do not have backup or external hard drive with my iTunes library. Will I be able to access my iTunes library when I purchase a new computer? It was the only computer authorized to play library.

My computer was totally destroyed & I do not have backup or external hard drive with my saved iTunes library from it. That was the only computer authorized to play library. I do not have an iPod or iPhone with any of that library (which has over $2K in music purchases & over 5K in songs I ripped). Will I be able to access my iTunes library when I purchase a new computer?

You should be able to access your past iTunes purchases. You'll need to re-rip your CDs See: HT2519 - Downloading past purchases from the App Store, iBookstore, and iTunes Store.

Time Machine Backup of external hard drive connected to IMAC

I have an external hard drive connected to my IMAC. I also have a 2TB Time Capsule connected to my network. I store all of my video (both events and projects from imovie) to the external hard drive to save space on the IMAC. Does the Time Capsule backup this external hard drive? When I open Time Machine I don't see where the external hard drive is backed up? The drive is formatted MAC OS extended (journaled).

nujac,
Time Machine backs up all locally attached drives unless you specifically exclude them in System Prefenences > Time Machine > Options.. icon.
You should be able to see this in Finder, enter TM and highlight the external drive. Click back to a prior date. Sometimes it takes a little while to fully populate the display since it's reading across the network, give it a few minutes.

How to backup an external hard drive plugged into a time capsule using time machine

How to backup an external hard drive plugged into a time capsule using time machine.
I want to move my itunes library from the mac HD to an external plugged into the time capsule, but I want to be sure this drive will still be backed up by time machine. I currentlly see no way to do this.

There is no way. You can connect the drive to your Mac and remove it from the Time Machine exclusion list. Then it will be backed up, but that will stop when you reconnect it to the TC. While it's connected to the TC, you can copy it manually to another AirPort Disk by following the instructions here (with a slight modification):

DB2 / Red Hat 5 : Backup to External Storage Failed

Dear gurus,
I've SAP ECC 6 running on DB2 9.7 FP2, RHEL 5.0
We can backup to internal disk, but when configuring backup to external storage (Maxtor Shared Storage II), there's this error.
I mount the external storage using cifs, with correct owner and permission (db2<sid> : db<sid>adm with 777 permission.)
The shared storage is: //192.168.1.8/mhp with mount point /mnt/mhp
When I backup using DB13 to /mnt/mhp, the file is created and the size continually grows constantly.
But when the backup is about to finish, the file then disappears, and DB13 returns "Database backup failed"
I see the db2diag.log, and here's the entry:
[db2diag.log|http://snipt.org/pYx/]
The message is not too clear for me.
Does anyone happen to come across the same problem as me?
Thanks for your help.
Best Regards,

Dear gurus,
If it is plain file like copy / move command to the storage, it can be done successfully.
I can also 'touch filename1' there. But for DB13 or DB2 backup command, it failed.
Markus, there's no particular technical things. We just choose cifs.
I've tried NFS but it said things like "Connection Refused" when I tried to mount -a.
I've tried also in different server, and it actually give the same result. So I think it's not SAMBA.
May I know what you mean by mapping the user?
I can make shared folder in the maxtore webgui management, and create user to own that folder.
Thanks for your help.

ITunes Error Code -36. Unable to BackUp to External Drive.

iTunes Error Code -36. Unable to BackUp to External Drive.
As of yesterday 9th Jan,2009, I am unable to backup up all
my 79Gb iTune tracks unto my external Iomega MiniMax Hard drive.
Which is very odd, as I never had a problem doing likewise
in the past.Each time it went smoothly and as planned.
Drag and drop procedures.
Here is the error message I keep getting every time I
try to execute the transfer:-
The Finder cannot complete the operation because some data
in"FBCIndex" could not be be read or written.
(Error code- 36)
Tried all previous soloutions including repairing and fixing
Mac Hard Drive using Disc utilities.
Should I do an Archive and Install or perhaps deleting the
iTunes preference files...all possible soloutions will be gladly
recieved.I'm in your hands.
My Music is my life... you probably
can relate to my level of anxiousness in this one?

*I should have been a Genius!*
Problem solved; I can now drap and drop to update
my itunes folder without any error messages etc,.
Memo to self and others.
ALWAYS, ALWAYS, ALWAYS when updating your OS
install the COMBO update and not what Software Update selects
for your particular Mac in Software Update.
