I'm a Mac user. Why did I fail to back up files or folders from the Synology Product to an external USB/SATA disk?
This situation may happen when the file system type of the external USB/SATA disk is FAT32 format, and could be due to:
- There are icons in the folders.
- The file name contains illegal characters in FAT32 format, such as \ / < > * ? | “ \r \t.
To back up files or folders in the above condition, you need to format the USB/SATA backup disk in Native format on the “Main Menu > Control Panel > External Devices” page.
Note: Formatting disk will delete all data on the USB/SATA disk. Please back up data on the USB/SATA disk before formatting it.
Why can't I automatically connect to my server in Data Replicator 3 even when the “Auto-connect on Data Replicator 3 startup” feature is enabled?
In order to automatically connect to the server with the Data Replicator 3, please make sure to first complete the following steps:
- The server is configured with a fixed IP address instead of via DHCP.
- The service of Data Replicator 3 is not blocked by the firewall or other anti-virus systems.
- The connection to the server is not occupied by other network services on the PC client. The auto-connect feature will work properly if other network services are disconnected.
Why can't I perform network backup from an rsync compatible server to my Synology product?
To perform network backup from an rsync compatible server, please make sure the following items are set up correctly:
- Make sure network backup service has been enabled for the Synology NAS. The option can be found at Backup and Replication > Backup Services > Network Backup Destination.
- When performing backup, make sure you are using “root” or “rsync” for the Synology NAS user name and “NetBackup” for the backup module, for example: rsync -a –timeout=600 /volume1/public firstname.lastname@example.org::NetBackup/test/, where 192.168.1.81 stands for the IP address of the Synology NAS.
- The installed rsync is version 2.6.6 or later, or rsync protocol version 29 or later. To obtain the correct rsync version, please go to http://rsync.samba.org/.
Why do errors occur when using Time Machine to backup onto shared folders exceeding 16 TB?
Due to limitations on Mac OS X 10.7 (and onward), Time Machine cannot backup onto shared folders exceeding 16 TB. Initializing a new backup task will result in Error Code 10 if the target shared folder exceeds this limit.
To avoid this problem, please choose either of the following solutions:
- Set the user quota on the volume containing your Time Machine target shared folder. At most, a user may be limited to using 4095 GB of a specific shared folder. To set a user quota, please do the following:
- Login to DiskStation Manager using an account with administrator privileges.
- Go to Main Menu > Control Panel > User and double-click the user created for Time Machine backup.
- Click the Quota tab and enter a value under the Quota column.
- Click OK.
- Create a volume that is smaller than 16 TB and set up your Time Machine shared folder on it. Please go to Main Menu> Storage Manager > Volume, and click Create to create a volume.
Why doesn't network backup work with my rsync-compatible client?
There are several noted rsync-compatible servers that encounter errors when using DSM’s network backup feature. You can find a list of these servers below. The main reason for these errors lies in the fact that the general behavior of rsync is not completely consistent. DSM’s network backup service fails when encountering these unexpected inconsistencies. Here is a list of servers that will not work properly with DSM’s network backup feature along with a short description of the encountered problems:
- OVH rsync server
- After using rsync remote shell commands to upload a directory, the rsync server is unable to find the uploaded directory at the expected path.
