Fast Incremental/Differential Backup; Archive Splitting; File-Level Security Settings - ACRONIS TRUE IMAGE - FOR MICROSOFT WINDOWS SMALL BUSINESS SERVER User Manual

6.3.7 Fast incremental/differential backup

The preset is 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 for Microsoft Small
Business Server 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.

6.3.8 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 2GB in size).
The preset is Automatic. With this setting, Acronis True Image for Microsoft Small
Business Server will act as follows:
When backing up to the hard disk:
selected disk has enough space and its file system allows the estimated file size.
The program will automatically split the backup into several files if the storage disk has
enough space, but its file system does not allow the estimated file size.
FAT16 and FAT32 file systems have a 4GB file size limit. However, the existing hard
drive's capacity can reach as much as 2TB. 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 backup 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.
When backing up to a diskette, CD-R/RW or DVD+R/RW:
Microsoft Small Business Server will ask you to insert a new disk when the previous one is
full.
Alternatively, you can select Fixed size and enter the desired file size or select it from
the drop-down list. The backup will then be split into multiple files of the specified size.
That comes in handy when backing up to a hard disk with a view to burning the archive
to CD-R/RW or DVD+R/RW later on.
Creating a backup directly on CD-R/RW or DVD+R/RW generally will take considerably
more time than it would on a hard disk.

6.3.9 File-level security settings

Preserve files' security settings in archives
By default, files and folders are saved in the archive with their original Windows security
settings (i.e. permissions for read, write, execute and so on for each user or user group,
set in file Properties -> Security). If you restore a secured file/folder on a computer
without the user account, specified in the permissions, you may not be able to read or
modify this file.
