Specifying how to manage disk space on your NAS server

There are a number of ways in which disk space can be managed through BackupAssist on your NAS server:

1. Use all available space (recommended)
   BackupAssist will check the NAS server for free disk space while a backup is in progress. If the NAS server is running low in disk space and cannot accommodate the new backup file, the oldest backup file on the disk will be removed. BackupAssist will continue to remove backup files in age order as required to ensure that enough space is free to store the new backup file. If your entire NAS server is dedicated to backup storage this option is recommended.
2. Use available space but always leave X Gb of free space
   Here you can define an amount of disk space to always leave free on the NAS server. BackupAssist will check the NAS server for free disk space while a backup is in progress and if the drive's free space goes below this value, the oldest backup file will be removed from the NAS server. BackupAssist will continue to remove backup files in age order as required to ensure that this amount of free space is always maintained on the NAS device.
3. Use a maximum size of X Gb for backups
   Here you can define a maximum amount of disk space that should be used for backup storage on the NAS server. BackupAssist will scan the NAS server for backup files while a backup is in progress and if the amount of disk space used for backup files goes above this value, the oldest backup file will be removed from the NAS server. BackupAssist will continue to remove backup files in age order as required to ensure that backup storage does not exceed this value of disk space.
4. Keep the last X backups
   Here you can determine the number of backup files that should be constantly maintained on the NAS server. BackupAssist will delete the oldest backup on the NAS server if this number of backup files is ever exceeded.
5. Keep backups from the last X days
   Here you can choose to have BackupAssist remove any backup files on your NAS server that are older than a specified number of days. For example: you may like to set this value to "14" to always have the last two week's worth of backups on the NAS server.
6. Unmanaged
   Here BackupAssist will continue to fill your NAS server with backup files. You will need to manually manage the disk space yourself. If the NAS server runs out of space and a backup cannot complete you will receive an error in your backup report alerting you to this fact.
