Maintaining multiple small backup locations on a single disk does not allow for tracking
changes in total disk space usage. At the same time, manual management of thousands
of archives in a location may be a serious problem. Practice is the best criterion for your
choice.
You can move, clear or delete existing backup locations or edit their size limitations and
storage period.
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, GB or TB
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 backups.
A storage period is the amount of time that is allotted for a user or the backup location to
maintain a file.
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. After that a full backup and a set of subsequent incremental backups
is created, then again a full backup and so on.
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.
An attempt to direct user/computer backup data to the backup server while space or
number quota is exceeded will not succeed. Backup to the full location will also be
prohibited.
An administrator can schedule a check of meeting the limitations. All archives on the
backup server will be checked and, if the space quota is violated or the maximum number
of backups is exceeded, the backups will be processed as follows:
Acronis Backup Server will combine the first full backup with the next incremental one
•
into one full backup which will be dated the later backup date. Then, if necessary, this
backup will be combined with the next, until the occupied storage space (or number
of backups) decreases to the preset limit. Thus, the archive integrity will not be
affected, in spite of the fact that the oldest backups will be deleted. This procedure is
called automatic consolidation.
The actual number of backups can exceed the Maximum number of backups by one.
This enables the program to detect the fact of quota violation and start consolidation.
