DS-Client configuration
The DS‑Client software is designed to perform unattended, scheduled backups of single computers or an entire LAN. To maximize the DS‑Client's performance, consider the following:
 
Use the latest supported operating system
Running the DS‑Client software on the latest supported operating system will boost backup speed.
Provide adequate CPU and memory
Since the DS‑Client software performs compression and encryption during the backup, it is CPU‑intensive. Use the Load Summary to determine CPU and memory use during backups (on the Reports menu, click Load Summary). If it is very high, you should consider a more powerful CPU and more memory for the DS‑Client computer.
Use multi‑processor systems
The DS‑Client software is designed to scale on SMP systems, when installed on Windows. Running the DS‑Client on such a system provides large performance boosts when compared with a single CPU configuration.
Use a dedicated database server
The DS‑Client uses a database to store backup logs (catalogs). When using the DS‑Client in a LAN configuration that can exceed a few hundred thousand backup files, the database update and retrieve speed can affect backup performance significantly. Use a dedicated computer for the DS‑Client database to provide faster performance.
Provide faster LAN connections.
When running the DS‑Client on a powerful system, LAN connections can become a bottleneck. Provide a faster LAN connection to significantly improve the backup speed.
Schedule appropriate number of backups
Scheduling too many backups at the same time will increase overall backup time due to CPU, memory and LAN connection over utilization. Use the Load Summary to determine CPU and memory utilization during backups.
