Backup Stor can be reached from Linux over SFTP, FTPS and SMB/CIFS. The host is backup.sayob.com and the user name is the one issued with your storage, in the form kdXXXXXXX.
SFTP — the recommended option
sftp [email protected]
Encrypted by default, a single port, and it supports key authentication — which is what makes unattended backups possible. See Setting up SSH key access to Backup Stor.
Inside the session, put uploads, get downloads, ls and cd navigate, and bye exits. For anything more than a few files, rsync over SSH is better — it resumes after an interruption and only transfers what has changed:
rsync -avz --progress /local/path/ [email protected]:/backups/
FTPS
lftp -u kdXXXXXXX ftps://backup.sayob.com
Use lftp rather than the plain ftp client: ftp does not support encryption, so your user name, password and data travel in clear text. If lftp is not installed:
apt install lftp # Debian, Ubuntu dnf install lftp # AlmaLinux, Rocky Linux
Mounting as a file system (SMB/CIFS)
Useful when an application needs to write to the storage as if it were a local directory. Install the packages, create a mount point, and mount:
apt install cifs-utils mkdir /mnt/backup mount -t cifs //backup.sayob.com/kdXXXXXXX /mnt/backup \ -o username=kdXXXXXXX,password=YYYYYYYY,nounix
For details, including automatic mounting at boot and keeping the password out of /etc/fstab, see Подключение услуги Backup Stor по протоколам SMB/CIFS и FTP/FTPS.
WebDAV
Not supported.
Which to choose
- SFTP for scripted and scheduled transfers — encryption and keys with no extra configuration.
- SMB/CIFS when software has to see the storage as a directory.
- FTPS if a tool you already use speaks FTP and nothing else.
Avoid unencrypted FTP in all cases.
If a connection is refused, check the user name and password first, then whether the port is blocked on the network you are connecting from — SMB in particular is filtered by many internet providers. If it still fails, open a ticket from your client area.
