In the File Server page, servers communicating with SMB or rsync protocol can be protected.
Depending on your source, you can create SMB Backup or rsync Backup tasks.
Before creating a backup task for a file server, you will need to connect to a file server first. Please follow the instructions below to add a file server.
Note: For Linux sources, block transfer can be configured at a later stage in the setup.
Please see the table below to learn the variations of final backup files on DSM with three different types of backup modes.
You need to set at least one policy if you check Apply the following methods.
Keep only the latest versions means the maximum number of the recent versions you may keep. The exceeding versions will be rotated based on the Grandfather-Father-Son (GFS) retention policy or will be deleted when no other retention policy is configured.
Synology employs the Grandfather-Father-Son (GFS) retention policy. You can configure the time ranges of backup versions to be retained for the following time ranges respectively: daily, weekly, monthly, and yearly. If more than one backup version exists within a time range, only the latest one will be kept. For example, if you set a policy as Keep the latest version of the day for 1 day for the backup task which will be run every hour per day, only the version backed up at 23:00 will be kept.
Please note that every configured policy overlaps with each other. For example, if you would like to set the policy as keeping daily backup versions in the first three months, weekly backup versions in the second three months, and monthly backup versions in the third three months. Please tick the checkboxes and insert the numbers as the below picture displays.
The duration of 24 weeks includes the previous daily backup versions of 90 days, and the first weekly backup will be equal to the seventh daily backup. The duration of 9 months also includes the previous weekly backup versions of 24 weeks and daily backup versions of 90 days, and the first monthly backup will be equal to the fourth weekly backup.
You can edit the information, including server address, port, account, and password of file servers.
