3.5.1 Backup locations, their quotas and time limitsBackup server is a networked computer where Acronis Backup Server is installed. A backuplocation is an automatically managed storage area for backups on a backup server. Anadministrator can organize one or more backup locations and set the overall limitations tosize/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 usersIndividual quotas and time limits determine every computer’s or user’s quota on a backupserver. This include1) maximum storage space, allocated to a user/computer, in Mb2) maximum number of backups3) maximum number of incremental backups for each full backup4) 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 becreated. The next backups will be incremental, until the maximum number of incrementalbackups is reached. Then again a full backup and a set of subsequent incremental backups iscreated, then again a full backup and so on.As appears from the above, when backing up to backup server, a user cannot select backupmode (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 initialfull backup. For example, if this parameter is set to 5, Acronis Backup Server will create onefull backup, then four incremental backups, then again a full backup and so on. For thisreason, this parameter is also called “maximum number of backups in an archive”. Archivehere means a set of subsequent incrementals and the base full backup.When number of backups or storage space exceeds the preset value, Acronis Backup Serverwill combine the first full backup with the next incremental one into one full backup. Then, ifnecessary, this backup will be combined with the next, until the occupied storage space (ornumber of backups) decreases to the limitation. Thus, the archive integrity will not beaffected, in spite of the fact that one backup will disappear. This procedure is calledautomatic consolidation.When storage period expires, Acronis Backup Server will delete the outdated archiveswithout notification.An administrator can run a check of meeting the limitations on a schedule (once, daily,weekly or monthly).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 profilesProfile is a set of parameters, assigned to each computer and user that backs up on thebackup server. Profile includes the backup location and the above limitations. When anadministrator adds a new computer or user to Acronis Backup Server database, they areassigned the default backup location, quotas and time limits. An administrator then canchange these settings by editing the respective profile.Copyright © Acronis, Inc., 2000-2006 19
