If you frequently backup data to network drives, think of limiting the network usage used by
Acronis True Image Server for Windows. To set the desired data transfer speed, drag the
slider or enter the bandwidth limit for transferring backup data in kilobytes per second.

5.3.7 Fast incremental/differential backup

The default setting – Use fast incremental/differential backup.
Incremental/differential backup captures only changes in data occurred since the last
backup. To speed up the backup process, Acronis True Image Server for Windows
determines whether the file has changed by file size and the date/time when the file was last
saved. Disabling this feature will make the program compare the entire file contents to that
stored in the archive.
This option relates only to disk/partition (image) backup.

5.3.8 Archive splitting

Sizeable backups can be split into several files that together make the original backup. A
backup file can be split for burning to removable media or saving on an FTP server (data
recovery directly from an FTP server requires the archive to be split into files no more than 2
GB in size).
The default setting – Automatic. With this setting, Acronis True Image Server for Windows
will act as follows.

When backing up to the hard disk:

If the selected disk has enough space and its file system

allows the estimated file size, the program will create a single archive file.
If the storage disk has enough space, but its file system does not allow the estimated file
size, Acronis True Image Server for Windows will automatically split the backup into several
files.

FAT16 and FAT32 file systems have a 4 GB file size limit. At the same time, the existing hard

drive’s capacity may reach as much as 2 TB. Therefore, an archive file might easily exceed

this limit, if you are going to back up the entire disk.

If you do not have enough space to store the image on your hard disk, the program will
warn you and wait for your decision as to how you plan to fix the problem. You can try to
free some additional space and continue or click Back and select another disk.
