121 Copyright © Acronis, Inc., 2000-2010Deduplicate backup only after transferring it to the vault (do not deduplicate atsource)This option is available only in advanced editions of Acronis Backup & Recovery 10.This option is effective for Windows and Linux operating systems and bootable media, when thebackup destination is a deduplicating vault.The preset is: Disabled.Enabling this option turns off deduplicating backups at source, meaning that deduplication will beperformed by Acronis Backup & Recovery 10 Storage Node after the backup is saved to the vault (thisis called deduplication at target).Turning off deduplication at source may lead to faster backup processes but greater network trafficand heavier load of the storage node. The eventual size of the backup in the vault is independent ofwhether deduplication at source is turned on.Deduplication at source and deduplication at target are described in Deduplication overview (p. 71).Save software RAID and LVM metadata along with backupsThis option is effective only for disk-level backups of machines running Linux.The preset is: Enabled.When this option is enabled, Acronis Backup & Recovery 10 will save information about the structureof logical volumes (known as LVM volumes) and of Linux Software RAID devices (known as MDdevices) to the /etc/Acronis directory before creating the backup.When recovering MD devices and LVM volumes under bootable media, you can use this informationto automatically recreate the volume structure. For instructions, see Recovering MD devices andlogical volumes (p. 273).When using this option, make sure that the volume containing the /etc/Acronis directory is amongthe volumes to back up.Use FTP in Active modeThe preset is: Disabled.Enable this option if the FTP server supports active mode and you want this mode to be used for filetransfers.3.4.2 Default recovery optionsEach Acronis agent has its own default recovery options. Once an agent is installed, the defaultoptions have pre-defined values, which are referred to as presets in the documentation. Whencreating a recovery task, you can either use a default option, or override the default option with thecustom value that will be specific for this task only.You can also customize a default option itself by changing its value against the pre-defined one. Thenew value will be used by default in all recovery tasks you will create later on this machine.
