Compress backups to save storage space.Intego Personal Backup is a comprehensive backup solution for Mac OS X, protecting you from data loss by making copies of your documents, applications, and system files onto external media.5 Steps you Need to Backup your Mac with Disk Drill: Download and install Disk Drill on your Mac. Set up an automated backup schedule in stealth mode. Create file backups in full, incremental, or differential modes, using templates for iTunes, mail, contacts, documents, and photos. EaseUS Todo Backup is used to back up data from any Mac device and reduce data loss.
![]() ![]() Disk Image Backup Mac OS XThe result is that the source and destination are always maintained as exact duplicates of each other.A bootable backup copies a volume with Mac OS X on it to a second hard disk so the new location can act as a startup disk. Changing file A on your desktop Mac and file B on your laptop means that, when synchronizing the two Macs, file A will be copied to the laptop and file B to the desktop Mac. Since you may update some files on, say, your desktop Mac and others on your laptop, a synchronization can keep both of these Macs up to date with the latest versions of each file. But after that, only those files that are changed on one side are copied to the other side, and, by default, items removed from one side are deleted from the other. The first time you run a synchronization, Personal Backup may copy many files to ensure that both the source and destination contain the same elements.

Backup DecisionsBefore you implement your backup plan, determine four things: You'll then be up and running without having to reinstall Mac OS X, its system updates, and your own applications. You can copy all the user files on your Mac to a safe location, then "restore" the bootable backup to your Mac by performing a bootable backup in the opposite direction. If you have a system problem on your Mac, you can connect the backup disk, restart your Mac while holding down the Option key, select the backup disk and start up your Mac. If, for example, you have a 250 GB hard drive in your MacBook, and a 1 TB external hard drive available for backups, your decision is easy: back up everything, since there's no reason to save a few gigabytes when you have so many to spare.If you're short on space, your decisions are more complicated. On the other hand, perhaps you consider photos and videos of office renovations much less important, so you back them up only once a month to a server in the office.Two criteria help you make decisions regarding which source files to backup: the files' importance, and the amount of space available for backup. For example, you might decide to make daily backups of important business files to DVDs that are then delivered to an offsite location (such as a safe-deposit box) once a week. The problem with the source and destination existing on the same device is that a problem with that device (such as a hard drive crash) could easily destroy both your originals and your backups, leaving you with nothing.Instead, we recommend you make backups to another device, such as a CD, DVD, or external hard drive. But if you have room, don't forget the Pictures, Movies, and Music folders! These are also in your home folder, next to your Documents folder.The destination for your backups could be on the same device as the source, although we recommend you use an external device for all backups except the most casual (and insecure). On Mac OS X, most of your personal documents are stored in the Documents folder of your home folder. Then, if there's additional space, applications and system files are important. Super mario galaxy emulator macIf you are merely making a clone of your hard disk, however, you can use an external hard disk that is the same size as your internal disk.When you use removable media (such as CDs or DVDs), Personal Backup will let your backups span multiple discs, asking you to insert a new disc as each one fills up. This ensures that there is enough room for the many files that change from one backup to the next. To save space (and copying time over a network), Personal Backup can make incremental backups that replace only those files that have changed or been created since the last backup.We recommend you take the total size of your source files and budget at least twice as much space on your destination disk. Consider how long you'll want to keep archives of your backups. If you have plenty of space compared to the total size of your source files, and are able to perform backups conveniently, there's no reason not to do them every day. Then, complete daily or weekly backups provide additional protection to cover all files, whether you have worked on them or not.Again, scheduling decisions will depend on the amount of space available on your destination device. For critical data, a backup of working files to external media (or a network location) every few hours is wise, and for professional documents, you may want to run hourly backups. If you lose it due to a crash or power outage at noon, you'll probably need three hours to restore the file - if that's even possible.To ensure that you don't lose such data, you should regularly back up your files. Ask yourself this: how long will it take to recreate changes made to lost files? For example, let's say you start working intensively on a file at 9 am. However, it probably won't need to access those old files frequently, or at all: therefore, it would probably store them in a compressed format (to save space), at an offsite location.
