...or differential backups. What's nice about Acronis True Image is that a description is usually provided for various functions in
Plain English.
You can set a password to protect the archive file from unauthorized access, and launch commands before and after a backup (for example,
stopping and starting services). Three compression levels are available for the backup sets you create — None, Normal, High and Maximum. The
higher the level of compression you select, the smaller the archive file will be, but the longer the backup can take. There's plenty of room to
experiment to find the best balance between compression to maximize backup storage space, and the length of time it takes for the backup to
complete. Keep in mind that some files don't compress as well as others. For example; if you have many digital photos in the .JPEG format, these
files will yield little if any compression improvements by archiving them with Acronis True Image's Higher and Maximum compression levels.
When backing up to CD or DVD ±R/RW media, image or file archives will rarely fit on a single disc. Acronis True Image can split the backup
archive file across removable storage media with ease. It does so automatically by splitting the file only when it's absolutely necessary,
completely filling one disc before requesting the next. This can save the number of discs you'll need for the backup. Or, you can specify the
archive file be split into the following industry-standard removable media sizes:
100 MB Zip Disk
650 MB CD-ROM
700 MB CD-ROM
4.7 GB DVD-ROM
Because Acronis True Image is able to back up your system in the background while you work, you can adjust the Backup priority. When set to
Low, the backup will proceed much more slowly than it normally would, but its impact on other processes and activity taking place on your PC is
minimal. Normal will permit the backup to proceed at normal speed with minor to moderate impact on system performance. High allows Acronis
True Image to process the backup at maximum speed, with the most impact on all other processes and activity taking place on your system.
I ran Acronis True Image on a system with an Athlon 64 X2 4400+ dual-core processor, and an Athlon 64 FX-55 single core processor — both
with 2 GB of DDR 400 RAM, performing full image backups to a share on a TeraStation NAS at each priority setting, while performing common
tasks on each system (E-Mail, web browsing, creating Word documents and editing photos with Photoshop CS). Low priority works the best on
single-core processors and Normal on dual-core or Hyper-Threaded processors. High priority should definitely be reserved for scheduled backups
when there is no activity on the computer, as just about anything you try to run will slow to a crawl or come to a screeching halt. Keep in mind
that your actual results, based on your particular hardware and other variables, will vary.
