Is there a comparable automatic back-up system to Time Machine for 10.4.11?
My dad has 10.4.11 running on a G4 tower.
I want to get him a back-up system that will save all his work. I myself have an Intel Mac running 10.6.8, with Time Machine saving all of my work to an external HD.
I know you can't use Time Machine with 10.4.11 Is there a comparable back-up system to TM that does automatic back-ups for 10.4.11?
(One other note--he still maintains Classic OS 9 on his system as well as 10.4.11. Will the back-up device also back up whatever he has on OS 9 as well as 10.4.11? And does it also back up the actual system software--the OSs 10.4.11 and 9--as well as all the files? So if he needed the backups, he would not need the system discs?)
Thanks for your help!
I'm sure Tr-Backup 5.1.7 will do everything you want, & far more that TM...

Backing up macbook with time machine for first time
I tried backing up my macbook for the first time, using time machine, to a new portable external hard drive formatted for p.c. The screen said do you want to erase the disc and i did. It said nothing about formatting for mac, but began to appear to be backing up my computer, and was running for 3-4 hours doing that. I walked away from the computer and came back an hour or two later, and there was a message on the screen saying error, could not create directory. I don't know if this was related to the initial backup, or if an hour later it tried updating the backup and it referred to that. How do I know if my computer is backed up properly. What do I do about the message about the directory. If I don't need this program to update the backup every hour, how do I change that. Also, I have a 1 terrabyte external hard drive on which I store all my raw photography files, can I plug that in and plug in another new external hard drive and back up the external hard drive to the other external hard drive using time machine as well? thanks for any suggestions, this is a little confusing the first time, Virginia
The backup frequency can be changed using e.g. TimeMachineScheduler and I think you can set Time Machine to backup external drives. (System Preferences --> Time Machine --> Options)

I have an IMac with an external hard drive set up as a Time Machine for automatic backups. I want to add a second external hard drive and load my Aperture Photo Library on to it so that the library can be shared by both me and my wife. Is there a way to automatically backup the photo library that will be on the second hard drive to the Time Machine hard drive?

I have my complete computer using Lion backed up on the time machine. Then I installed Mountain lion. I do not like it at all. Is there a way I can remove ML and put my old Lion system back pin my computer?
If you have got a backup, press Command and R keys in boot and restore an old backup. You can install Snow Leopard and upgrade to Lion if you haven't got the backup

After Full System Restore, Time Machine Won't Complete Back Up
I successfully did a full system restore using Time Machine. The Restore worked but Time Machine has not worked since I completed the Restore.
It says "Unable to complete backup. An error occurred while copying files to the backup volume.." Please help. I don't know what to do. The TM Widget Activity Log is posted below:

There seems to be a problem with that file. See the blue box in #C3 of [Time Machine - Troubleshooting|http://web.me.com/pondini/Time_Machine/Troubleshooting.html] (or use the link in *User Tips* at the top of this forum).
Note that the /private folder is normally hidden, so you'll need to click the +Show inisible items+ box. -
Had hard drive renewed due to product recall (iMac) backed up complete system on time machine . Had the drive done got mac back tried to reinstall from time machine .The new drive tells me that the space has been taken up but can't find where the file have gone. Need to free up the space that the ghost file take up so I can drag drop from ex drive onto harddrive
Here's the scoop, new friend.....
When you boot into Time Machine you'll get the same OS X Utilities screen as you would if you booted into the Recovery HD. So, from there go into Disk Utilities to erase/format your internal drive. After that's done, back out to the OS X Utilities screen and select the restore option. Just follow the prompts to select the TM back up date you want to restore from and where to restore it to. Pretty straight forward. -
I haven't backed up my computer in over a year. When I tried to back it up today, Time Machine says 'an error occurred while creating the backup folder.' When I check the side of the partition where I manually saved old photos and documents (including all the pictures from the year I studied abroad/traveled a bunch), the folders are there, but NONE of the files are.
Does anyone have any idea what the problem might be, or how I could fix it? I really don't want to lose all those photosSo you were doing a time machine backup to another partition on the same hard drive? Just trying to gather some information so i can provide a helpful response.

Can I back up computer with time machine on lion then reinstall snow leopard and restore from backup safely?
If your machine came with Snow Leopard or earlier and you have your install disks, yes, you can reinstall SL. However, you will need to erase the entire hard drive so you will lose all your files. Also note that there are some apps (such as Mail) which can't be downgraded "automatically" such as with a restore from Time Machine. Here is some info on TM:

Kernel Panic, Restored System Using Time Machine but Problems Still Persis
SOS! Please, please, please help. I'm at a loss here. I have an 300 GB iMac with a 32 GB partition for Windows. I backup to an Iomega UltraMax 500 GB external hard drive. Let me know if more info is needed. I went through the checklists to resolve a kernel panic, and nothing has been working. Here's the background:
I recently encountered a kernel panic (I saw the screen discussed in the "What is a kernel panic?" article). It started when Firefox 3.2 beta was running. It froze and eventually the system froze. I repaired disk permissions, and I was able to boot up, but it took awhile to boot up. Some things weren't right once it was booted; I lost some keyboard functionality, system settings (screen saver, display settings, etc), etc. I attempted to repair the disk (using disk utility while booted from leopard install disc), but it failed (generated an error, said it couldn't repair disk). So I did the next thing and restored the system from Time Machine. Things seemed to be alright.
And about a couple days later, Time Machine starting encountering errors and failed to backup (it failed while attempting to backup 300 MB). The system also started to get slower, and it eventually froze. So I restored again from Time Machine. Seemed to be alright, but again it eventually slowed and started freezing.
I can't retrieve the panic log. I think it was erased with one of my system restores. I went into Time Machine to look for it, and it's nowhere to be found.
So, I tried to repair my disk permissions. That succeeded. But the disk repair failed again. I restored again from Time Machine. Same thing: things seem okay, but Time Machine isn't able to back-up (it's pretty much non-responsive, even after I told it to stop, it just says "stopping"), things are a bit slow and some applications are unstable (Firefox crashed for no apparent reason). I just found this under /Library/Logs/Crash Reporter:

Windows XP ran fine from my other partition at this point. I'm wondering if my Windows partition has something to do with it (I chose FAT32 instead of NTFS file system)?
Please help. Will erasing the drive, reinstalling from the leopard disc (10.5.4), and restoring select applications/folders/files help, instead of from a system restore from Time Machine?
Your help is immensely appreciated!Thanks for responding.
So under the partition tab, I should reformat to one partition, reinstall Leopard, and see what happens from there? Selectively restore applications, music, pictures to my system once it's reinstalled and properly updated? Anything else I may need to do or restore?
Why not reformat under the erase tab, zero out the disk, and reinstall? Any difference?
Just a little worried and unsure is all. If it's a hardware thing, I can accept that and take it in to be serviced. But, if it is a software issue, I don't want to do any irreparable harm during the erase-and-reinstall process. Just want to make sure I get it right.

I am going to back up to Time Machine for the first time
which I know sounds nuts. I was manually doing it for the past 6 months- don't ask why.
Do I have to completely wipe out my Lacie and do any formatting to it? Or do I just delete everything from it and set my Time Machine to default backup to that drive and go from there as if I'm doing it for the first time?
Also, I don't keep my EHD attached constantly to my laptop- I assume that is not a problem and whenever I hook it up, I can then ask TM to go to work?
Sorry for the basic questions- appreciate the help!
Thanks,
BerniceI haven't burned a CD in years. My old MacBook doesn't have a DVD burner.
The biggest issue is the size of your various drives. For Time Machine, your Time Machine drive should be three times the size of the drive you are backing up. If you don't quite have that (and I don't), you can get away with three times the amount of data you are backing up. Whichever configuration gives you that equation should be the one you use for Time Machine. You can partition one of the external drives so that one partition is big enough for Time Machine and the other is used for other purposes, such as archives. I have one external drive configured like that. If you don't have enough room to partition, then dedicate one drive to Time Machine and the other to archives and/or clones.
Some people feel it is very important to maintain a long Time Machine history and migrate that to new drives. I don't quite understant that. I use Time Machine for backups, nothing more. I blow away all my backups on a fairly regular basis and start a fresh one. I don't need six month old versions of files. If I accidentally delete a file, I will notice sooner than that. If I have a hardware failure, I only need the last backup.
I currently have those bootable clones only because my MacBook is in a funky state right now (long story) and my MacBook Pro is a work machine bound to an Active Directory domain. I can't rebuild that system by myself without IT from work and that would be difficult for me (longer story). I don't consider bootable clones to be a regular part of my backup strategy. They are useful snapshots and archives for specific times when I feel I need them. -
I recently updated my IMac software to the latest version, now i can't see by WD back up drive in time machine. its conected to the firewire port ok and i can see it if i check firewire connections. The drive works ok on an old windows laptop. Any ideas.

Is it possible that i did this whilst updating the OS software whilst leaving the WD drive connected.
It's a good idea to eject and disconnect external HDs, just in case, but that shouldn't cause a problem.
Why when setting up time capsule, does it only look for WIFI drives through airport.
I think you're confusing Time Machine (the backup software) with a Time Capsule (Apple hardware combining a wireless router and HD). Unless you have a Time Capsule you want to back up to, there's no point to clicking the Set Up Time Capsule button, if that's what you mean:
I've attached the Firewire bus from system profiler, dont understand why i can see it there but not in TM.
There seems to be some sort of problem with the drive, since Disk Utility thinks it's fixed, but immediately the problem returns (per the first sample you posted).
How old is the drive?
If it's within the warranty period, you might want to contact WD or the place you bought it. -
Backed up data from Time Machine
Hi,
I just installed Leopard on my iBook G4 and for Time Machine I used my 250 GB external HD from iomega, which is very good. I always thought that at the beginning Time Machine copies everything on the external HD, and then every hour it just checks what has been changed and copies only the changed files over. I just browsed through my external HD and saw that, as a matter of fact, Time Machine backs up every file every hour. I noticed this because in the "Backup" folder (on the ext. HD) there were many other folders with time and date. You could see that for every hour Time Machine made a folder, with all my documents inside. Is this right? Does Time Machine really back up the whole computer every hour? Or did I just see something wrong? Because if Time Machine really backs up 30 GB of data every hour, I have a slight problem with a 250 GB external HD.
Thanks!Open up System Preferences / Time Machine.
Now right-click (or CTRL-click) on the Time Machine icon in the Dock and select Back Up Now from the menu that pops up. Watch what happens in the Time Machine preferences pane. That will show you how much is being transferred. You can also watch when the time for the next hourly backup approaches.
You can also see this info after the fact by going to Applications / Utilities / Console (select "All Messages" in the column on the left) and looking for the information messages put out by the "backupd" process that is actually doing the work.
What you'll find is that far less than the whole system gets transferred. However, despite that, each Time Machine snapshot in time includes the COMPLETE file system? How does it do it? By including "hard links" -- a special form of file pointer or alias -- for each file or folder that was actually transferred in an earlier incremental or initial backup. When Time Machine discards old backups (to winnow hourly backups down to one backup per day, and eventually one backup per week), the file system doesn't actually delete a file on the Time Machine disk unless all the hard links to it are also gone. So if a file was transferred in a given incremental backup, it will STAY on the Time Machine drive until all subsequent "hard link" references to it are deleted -- even though the backup during which it was originally transferred has long since been deleted itself.
So if you delete the real file on your computer, no new hard links get created as part of each subsequent Time Machine backup, and eventually (as the disk gets full and old backups are discarded) the last reference to that file will be discarded and the file itself will also actually be deleted from the Time Machine drive. And if you change a file, the new version gets transferred, but the old version remains on the Time Machine drive so long as there are still hard link references to it which have not yet been discarded.
From a user point of view, you don't have to know what got transferred during a given incremental backup, because each and every time window into your Time Machine always shows you the COMPLETE file system as of that point in time (minus anything you have put into the Do Not Back Up list).

Is there a way to backup mail messages in Time Machine?
New MacBook Pro. New backup hard drive. When I use Time Machine to backup my new laptop I see that my mail messages are not being backed up. In 10.6.8 they were backed up in a folder labelled Library. Is there a way to backup all my mail messages through Time Machine? Sorry not a techie, so please keep it simple.
Bring the Mail browser window forward, then select Enter Time Machine from the Time Machine menu, which is represented by a clock icon in the menu bar. If you don't have that menu, select ▹ System Preferences ▹ Time Machine ▹ Show Time Machine in menu bar.
Scroll back in the time-travel view to the most recent snapshot containing the messages you want to restore. Select the messages, then click Restore. The messages will be restored to a new mailbox. From there you can move them wherever you like. -
My new LaCie external hard drive is 'seen' by my iMac and I can go into the Finder and open files and folders. I am using the hard drive for Time Machine back up. However Time Machine says it can't find the drive.
The same thing happened recently between Final Cut Express and my other LaCie external hard drive used as the Scratch disk. It fixed itself.
I've run out of ideas. Help would be very much appreciated. Thanks.have you done some searches on FCPx and time machine? Is there a known issue with using a TM drive with FCPx? dunno but ...wait...I'll take 60 sec for you cause I'm just that kind of guy.... google...." fcpx time machine problem" Frist page link

You cannot have time machine backups on your hard drive if you intend to use it in FCPX.

I understand that a number of people have lost data since installing Mavericks on their Western Digital external drives. Has anyone any futher info. Or is there a better way of backing up my computer. Thanks. Lee
