What is Time Machine Backup
Making backup of important data is always a necessity but people always forget to. For Mac users, there’s a great application called Time Machine that is able to create backup of your Mac files, applications, folders, volumes and even the whole Mac system.
The most wonderful feature of Time Machine is that it automatically backs up your Mac everyday as long as the backup drive has enough space, so that you can select the version of the files that you want to restore depending on your need. With Time Machine backup, you’ll never be worried about losing important data from your Mac.
What can Time Machine backup
HFS + disks and partitions on Mac, as well as connected hard drive, USB, FireWire with HFS + system too. You can backup everything on your Mac, including Mac system, applications, accounts, preferences, emails, music, photos, audios and documents with Time Machine after activating it.
The space of a Time Machine
Since Time Machine would probably backup the entire Mac system and it updates every day, the backup can be very big. This is the reason why it’s strongly suggested to select a drive which is two times bigger than the system drive as the Time Machine disk.
The schedule of Time Machine
After the first set up, a Time Machine backup will be created. Normally, Time Machine works hourly (if your Mac is on and the drive is working). You can also click the “Backup Now” on the Time Machine icon bar to backup immediately.
The needed time of making a Time Machine backup:
It’s hard to tell. The backup time depends on the amount of data, the data transferring speed of your drive. Normally, the less files and the better drive speed, the faster.

Time Machine Doesn't Support Windows Drive: If your drive is a NTFS or FAT one, which is not supported by Mac OS X, you'll need to erase drive to make Time Machine backup on it. This process will remove all files on the drive.
Common Backup Failures
A Time Machine can’t be set on the drive: When this issue happens, please make sure your disk has enough space for the backup, also check that the external hard disk or FireWire drive is connected with your Mac
B Initial disk issue: If it’s the first time your set your drive as Time Machine backup drive, please ensure it’s a OS X supported disk (normally with HFS + data system). Normally format your drive can solve this problem.
C "Aborting backup because indexing a file failed": Usually, wait for next backup schedule or select “Backup Now” will solve this issue. Otherwise, there might be something wrong with that file. You can find that file from finder and check what’s wrong or directly remove it, and then the backup will continue.
D Backup is slow: It’s slow might because there’re too much data, the data transferring speed is slow when using external hard disk or FireWire as backup disk, or the space on backup drive is not enough. You can wait or clean backup disk.
E Unexpected delete backup: This is because the system is automatically deleting or thinning the backup. As we all know, the backup keeps growing as we use the Mac. It’s not a big problem.
F "The backup disk is full," or "This backup is too large": When this messages shows, the space on your drive might not be enough for a new backup. You’d better select a bigger drive to create new backup or delete needless data on that drive.
Disadvantages of Only Making Backup
Though creating backup of important data using Time Machine, or Time Machine alternatives like cloud backup and other software is a great way of avoiding data loss, there’re still disadvantages.
- Backup might fail while using third-party backup software or online backup services due to internet condition and some other reasons.
- Some users might forget using Time Machine to create backup or don’t want to use it because it takes too much space.
Data Backup and Restore
Actually, you need to take both backup and recovery seriously. Backup without thinking about recovery is not actually backup, and backing up is just the very first step. When disaster like data loss happens, and you don’t have backup or the backup fails, there’re several tips for you to keep in mind:
- Files are not really lost from your drive. When they’re lost or deleted, they’re not permanently removed. They’ll be marked as inaccessible data and awaiting new data in the drive to overwrite them. The truth makes it possible to recover your precious files without Time Machine backup or other backup formats.
- The priority to get lost files back is to stop using your drive or device as quick as you can. Any minor activity on the drive might cause data overwritten.
- Then you can look for a reliable and powerful Mac data recovery utility from the internet.
