3.5.1 Backup locations, their quotas and time limits

Backup server is a networked computer where Acronis Backup Server is installed. A backup
location is an automatically managed storage area for backups on a backup server. An
administrator can organize one or more backup locations and set the overall limitations to
size/storage time for every location, i.e. quotas and time limits. An administrator can Move,
Clear or Delete existing backup locations or edit their Quotas and time limits.

3.5.2 Quotas and time limits for computers and users

Individual quotas and time limits determine every computer's or user's quota on a backup
server. This include
1) maximum storage space, allocated to a user/computer, in Mb
2) maximum number of backups
3) maximum number of incremental backups for each full backup
4) maximum storage period for the user's/computer's archives.
These values define how Acronis Backup Server itself will handle the backup archives.
At first backup of the computer/user's data to the backup server, a full backup will be
created. The next backups will be incremental, until the maximum number of incremental
backups is reached. Then again a full backup and a set of subsequent incremental backups is
created, then again a full backup and so on.
As appears from the above, when backing up to backup server, a user cannot select backup
mode (full, incremental, differential). The backup mode will be set by Acronis Backup Server.
Please be aware, that in fact maximum number of incremental backups includes one initial
full backup. For example, if this parameter is set to 5, Acronis Backup Server will create one
full backup, then four incremental backups, then again a full backup and so on. For this
reason, this parameter is also called "maximum number of backups in an archive". Archive
here means a set of subsequent incrementals and the base full backup.
When number of backups or storage space exceeds the preset value, Acronis Backup Server
will combine the first full backup with the next incremental one into one full backup. Then, if
necessary, this backup will be combined with the next, until the occupied storage space (or
number of backups) decreases to the limitation. Thus, the archive integrity will not be
affected, in spite of the fact that one backup will disappear. This procedure is called
automatic consolidation
When storage period expires, Acronis Backup Server will delete the outdated archives
without notification.
An administrator can run a check of meeting the limitations on a schedule (once, daily,
weekly or monthly). All user's/computers archives on the backup server will be checked and,
if some quotas and time limits are exceeded, the above processing will be executed.

3.5.3 Administrator profiles and User profiles

Profile is a set of parameters, assigned to each computer and user that backs up on the
backup server. Profile includes the backup location and the above limitations. When an
administrator adds a new computer or user to Acronis Backup Server database, they are
assigned the default backup location, quotas and time limits. An administrator then can
change these settings by editing the respective profile.
