ACRONIS BACKUP AND RECOVERY 10 SERVER FOR LINUX - UPDATE 3 User Manual page 24

GFS by Acronis
With Acronis Backup & Recovery 10, you can easily set up a backup plan that will regularly back up
data and clean up the resulting archive according to the GFS scheme.
Create the backup plan as usual. For the backup destination, choose any storage device where
automatic cleanup can be performed, such as an HDD-based storage device or robotic tape library.
(Since the space freed on the tape after cleanup cannot be reused until all the tape becomes free,
take into account additional considerations when using GFS on a tape library.)
The following is an explanation of the settings that are specific for the GFS backup scheme.
GFS-related settings of the backup plan
Start backup at:
Back up on:
This step creates the total backup schedule, that is, defines all the days you need to back up on.
Assume you select backing up at 8:00 PM on workdays. Here is the total schedule you have
defined.
"B" stands for "backup".
Weekly/Monthly
This step forms the daily, weekly and monthly cycles in the schedule.
Select a day of the week from the days selected in the previous step. Each 1st, 2nd and 3rd
backup created on this day of the week will be considered as a weekly backup. Each 4th backup
created on this day of the week will be considered as a monthly backup. Backups created on the
other days will be considered as daily backups.
Assume you select Friday for Weekly/Monthly backup. Here is the total schedule marked out
according to the selection.
"D" stands for the backup that is considered Daily. "W" stands for the backup that is considered
Weekly. "M" stands for the backup that is considered Monthly.
Acronis uses incremental and differential backups that help save storage space and optimize the
cleanup so that consolidation is not needed. In terms of backup methods, weekly backup is
differential (Dif), monthly backup is full (F) and daily backup is incremental (I). The first backup is
always full.
The Weekly/Monthly parameter splits the total schedule into daily, weekly and monthly
schedules.
