Backup Splitting - ACRONIS BACKUP AND RECOVERY 10 SERVER FOR LINUX - UPDATE 3 User Manual

3.3.1.10 Fast incremental/differential backup
The option is effective in Windows and Linux operating systems and bootable media.
This option is effective for incremental and differential disk-level backup.
This option defines whether a file change is detected using the file size and time stamp or by
comparing the file contents to those stored in the archive.
The preset is: Enabled.
Incremental or differential backup captures only data changes. To speed up the backup process, the
program determines whether a file has changed or not by the file size and the date/time when the
file was last modified. Disabling this feature will make the program compare the entire file contents
to those stored in the archive.
3.3.1.11

Backup splitting

This option is effective for Windows and Linux operating systems and bootable media.
The option defines how a backup can be split.
The preset is: Automatic.
The following settings are available.
Automatic
With this setting, Acronis Backup & Recovery 10 will act as follows.
 When backing up to a hard disk:
A single backup file will be created if the destination disk's file system allows the estimated file
size.
The backup will automatically be split into several files if the destination disk's file system does
not allow the estimated file size. Such might be the case when the backup is placed on FAT16 and
FAT32 file systems that have a 4GB file size limit.
If the destination disk runs out of free space while creating the backup, the task enters the Need
interaction state. You have the ability to free additional space and retry the operation. If you do
so, the resulting backup will be split into the parts created before and after the retry.
 When backing up to removable media (CD, DVD or a tape device locally attached to the
managed machine):
The task will enter the Need interaction state and ask for a new media when the previous one is
full.
Fixed size
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. This comes in handy when creating a backup that you plan to burn
to multiple CDs or DVDs later on. You might also want to split the backup destined to an FTP server,
since data recovery directly from an FTP server requires the backup to be split into files no more than
2GB in size.
