Applications :: How Long Would Full Backup Of 900GB Of Data Take Using Time Machine
May 12, 2010
How long would it take to backup 900GB of data doing a full back-up using TimeMachine and my MacBook? My MacBook being a 2009 model with 2.13 GHz Intel Core 2 Duo and 4GB 800 MHz DDR2 SDRAM.
I have:
1 x MacBook 160GB drive
1 x Imoega minimax 500GB drive (firewire or USB 2 connection possible)
1 x Seagate 320GB drive (USB 2 only connection)
I have a 400 firewire port in my MacBook in addition to 2 USB sockets, as well as fireWire hub with power supply, should I wish to run 2 or more firewire devices at once, into the 400 firewire port.
My current backup drive is a Samsung USB2 1TB drive but for reasons that will hopefully become obvious below, I will need to purchase a new drive. I think a 1.5TB or 2TB would be fine and I guess a 400 firewire port is still better than USB2, even though it's only 400. However I'm not sure about the time issue.................

I have looked into this a lot already. It is to much that Time Machine backs up every single hour! It would be nice to set it to something like 3 or 5 hours. I have tried a 3rd party app to do this, but... If my computer was off or asleep when it was supposed to back up, it would get an error. It would not just do the backup when i turned it on or when it came out of sleep like stock Time Machine does. I have also seen a way to change the time incraments in the Terminal.(I am very good with it, not a noob) I have tried this and it screws up time machine completely. Maybe it does not work with the newest OS X. By the way... I have a 2010 MacBook Pro, got it 2 months ago.
Does anyone know a solid 3rd party app, that will work seamlessly. Or has anyone changed the time in Terminal and are currently using something different than 1 hour. There is a lot of examples online, but I would like the codeing that you literally used.

New to MAC and buying a OWC Mercury Elite-AL Pro

Should I use Time Machine or is the included software, Prosoft Engineering Data Backup 3 a better option?

I have a MacBook Air and a Time Capsule - both from november 2011.Using Time Machine is givning me som problems.It works fine for some days, an is backing up as planned.But at least 5 times since I got the Time Capsule, Time Machine is asking to make a full Backup, and when I look in Time Machine, it says that there is no "old backup". It has been runing since november 2011.When I start a new backup, as it ask for, it takes at least 24 hours to finish - some times even longer.Is this normal? If not, what do I do?

The Apple store sales person told me that I cannot backup my installed applications nor the OS with Time Machine. I have the latest version of Leopard. Lets say my hard disk crashes. Do I have to reinstall all the apps from scratch? Is there a backup program other than Time Machine? Should I be using dd?

I want to download Lion OS and I will call Apple for help, but I know they will ask if I've backed up everything. I'd like for Time Machine to completely back up my hard drive but I can't seem to find out how to make it do that.

I just got a message that my Time Machine external backup disk is full. I have another external drive I can use, but buying drives every few months is going to get expensive.
I was wondering what others are doing in this situation.
Is anybody archiving the Time Machine backup? If so, what software are you using and where are you storing your backup?
What kind of backup plans are you using with Time Machine?

After a catastrophic HD crash I bought a small 250GB external hard-drive an started to use Time machine. Since my Mac was freshly formatted, I tend to keep it tidy and clean and keep good track of what comes in. I noticed my time machine backing up 15 GB of data which allegedly would have been added within two days. I could absolutely not trace this on my computer nor when I compared current folder contents with the most recent backup. Downloads, Apps., System are all excluded from my time-machine and couldn't represent such a dramatic data increase on my separate HD.

I'm doing an initial backup to a Time Capsule and I want to make sure all my data was copied successfully. Does Time Machine verify that the data was copied successfully or does it just send it and hope everything copied alright? I know this is the kind of question only the Apple developers would know for certain, but hey, sometimes folks on these forums are surprisingly knowledgeable so I figured I'd ask here.

I decided to restore to a Time Machine backup I had done a few days earlier, hoping that I would just "start" fresh. Without realizing it, I had inserted the Leopard install dvd that came with my computer, and restored to my 10.6.6 backup. I got the "You must restart your computer" error, which I found out was a result of using the Leopard disk. So, I redid the restore using a Snow Leopard installer on USB.
After this, everything appeared to be working fairly well. However, today, I've started to get system crashes quite frequently, and at times I haven't been able to properly shut down or restart. I noticed that Spotlight was indexing, and would hang at "3 hours remaining" or "estimating time left." Right now, I have created a second admin account, and I have disabled indexing. It seems to be working, at least temporarily, because I'm using it right now.

My external disk which I use for Time Machine was replaced and the time machine files on it put onto the replacement disk. However although my computer(Imac intel using Leopard 10.5.6.) recognizes the disk as the back up disk for Time Machine (including the oldest backup dates and latest backup dates in the time machine preferences), it attempts to perform a complete back up of my HD instead of only a small incremental back up of the new files.

Back in March my system crashed. I have a vmware external SSD drive that lost its formatting. Any how, I had been using time machine before it crashed. Now it says my drive is full. Its like its not deleting old backup files. I have a 1 Tb external usb drive that I back up too. I am using OS X Mavericks. Not sure what I am supposed to do to fix it. Cant afford another data crash like that.

I'm getting a new macbook. Currently I use time machine as a backup tool and was wondering if I should use it to transfer all my data to the new mac. One benefit of a new harddrive is the fresh install without all the junk that has built up over the years right? So wouldn't time machine just be transferring all the junk and stuff I want to the new mac? or is time machine smarter than this.

So I just successfully migrated all of my data and settings from my old iMac to my new 27 inch iMac using the Time machine backup on my Western Digital 1 TB external hard drive. Aside from the Time machine backup folder I also dragged a few other things over to the external hard drive because there was so much extra space on it. The drive is not partitioned.
So I'd like to start using Time machine with this new 27 inch iMac but the empty space that's left on the external hard drive is barely large enough to cover what I now have on the internal hard drive on my new 27 inch iMac. If I were to remove the Time machine backup from my old iMac there would be plenty of space again unless starting Time Machine on this new 27 inch iMac will just copy right over that backup file? Everything on this new iMac, the data and settings and so forth, is exactly the same. So is the user account. However the previous Mac was running Leopard while this new iMac is running Snow Leopard.
So if it doesn't copy over the old backup it will just create a new backup file? And if it does create a new backup file is there any point to keeping the old backup file since I no longer have the old iMac and wouldn't be able to access it again? Obviously if I didn't have to keep it I could erase it which would create plenty of extra space for me to start using Time machine again but with this new iMac.

We are a PC to Mac convert and still trying to understand some basics. We have an iMac 21.5 and expecting delivery of a external 1.5 TD drive. More than we'll even need, but dirt cheap. We also run Windows 7 64 bit through VMware Fusion. The only reason for that is the Windows version of Quicken is a better product the the Mac version.
We will back up pics, Videos, etc., on the iMac under MacOs with Time Machine. Can Time Machine also backup the quicken data files from the Windows 7 VM machine? I hoping we do not need to maintain separate backup drives to manage the different type of file formats between Windows and Mac. I hoping this can be managed through one place...Time Machine.

After I had a full backup to iomega external hard drive I wanted to see photos in iPhoto library by using Time Machine. I can see the iPhoto Library icon on Time Machine, but when I click on an icon it does not open the folder and I can't see the pictures stored on iomega external hard drive. All other backed up documents I can see and restore if I need it.

I excluded for one TM backup a sparse bundle disk image that I have been backing up regularly. I then immediately removed the sparse bundle disk image from the TM exclusions list, and now TM wants to back up the entire sparse bundle disk image, which contains an iPhoto Library (80GB). It seems that TM does not "see" the previous disk image backups.

I recently purchased a Mercury Elite-AL Pro from OWC and it included Prosoft Engineering Data Backup. Are there advantages in using Time Machine vs. Prosoft Engineering Data Backup or vice versa? Also, what about something different like Carbon Copy Cloner? I'm looking to do this right the first time.

I've spent a good deal of time over three days trying to do something that I think is both doable and shouldn't be all that hard. I have a 750gb external HD attached to a Mini, and I'd like to use that drive to do TM backups for the Mini, as well as three MacBooks.
But I can't seem to get access to the backup drive from the laptops to either get going in the first place, or to remain available for TM. I get "volume can't be mounted" errors, "image can't be mounted errors", etc. I find that I can't ever eject the backup drive from the Mini (always told an application is using it...even if I've just booted up the Mini). And with one of the MacBooks, even a direct FW connection to the drive doesn't result in the drive showing up in Finder.
Isn't this a pretty straightforward thing to do? Is there a step by step somewhere that might help me figure out what I'm doing wrong, or what I need to fix? Should I reformat the drive again and start over (there are no important backups on it yet)? By the way, the drive is formatted Mac OS Extended (Journaled).

I have a linksys wrt610n wireless router that isn't set up yet. You can attach USB drives to the router to use as a nas. I can't find if time machine will use it or let me use a drive attached to the router for my backups.

I connected my windows removable disk to my colleague's mac to transfer some data. Accidentally her system started a time machine backup on my removable disk. Although we stopped it during middle of the process, now my disk is no longer recognizable in windows and all I can see under a mac system is her backup file.
The process took a very short time. I wonder if it has deleted everything. Is there any chance I can get the overwritten data back? They are very important to me.
Besides, is it a common problem of time machine backup? It is too dangerous for the removable disks.

if i am running my new lion OS on drive #1 and i have a Raid1 array on drive #3 and #4 with all my DATA - can i back this up using Time Machine? i would like to place my OS's on a single drive and have my DATA in a raid array but if this means that i lose the ability to retain a Time Machine backup of my data i will simply upgrade to Lion and keep the data on this drive so it can continue to get backed up in time.

I have a 3rd Party NAS (Iomega Home Media Network Cloud Edition 2TB) and MacBook with OSX 10.6.8. I did run a first TM full backup over Ethernet (around 240GB) because of the extremely slow transfer speed over WiFi via the AirPort. It went Ok (after several tries and reading here in the forum). Then, I disconnected my MacBook from the wired network, so futures frequently backs-up happen wirelessly, however, it seems that it did not recognize the first full back-up, asked for re-doing it again from scratch and erased my first full-backup-over-Ethernet.
I've seen that the MAC address is used as part of the sparse bundle file name; obviously, there will be a conflict here because Ethernet and AiPort do not have the same MAC address (of course !).I will run a brand new full first backup over Ethernet, but I'd like to know what do I have to do for getting it recognizable for futures backups over AirPort?

After some problems with Time Machine backup, I removed a bunch of stuff from my internal hard drive, reformatted my external HD used for backups, and started a new full backup. Time Machine has been running for about 24 hours and gives me a status of Backing up: xx GB of yy GB. Both xx and yy keep growing (apace) so that I don't believe xx will ever equal yy.
To cryptic? Here are real numbers. My internal disk being backed up contains 469.39 GB. Backup status now says Backing up: 685.78GB of 754.42 GB. Both numbers just keep growing. I'm happy to let Time Machine overnight (again) but, really, this can't be normal.
