By attaching iSCSI or Fibre networks with tape and disk devices through intelligent switches, a SAN lets you easily manage exploding data volumes. Backup Express leverages its distributed architecture to support SANs and allow UNIX, Windows, Linux, NetWare/OES and SLES servers, and NDMP-compliant devices to share tape resources in a SCSI, iSCSI, or Fibre-switched environment. By sharing devices, organizations maximize their tape hardware investment.
SAN Resource Sharing (SRS) allows tape devices (standalone or in a robotic library) to be dynamically shared among multiple Backup Express device servers. Tape drives are assigned and re-assigned as backup and restore operations dictate. The Backup Express master server manages all resource allocations in the enterprise.
For specific compatibility information see the interactive Backup Express Supported Technologies Database.
Backup Express SRS provides dynamic drive sharing by managing resource requests from a single location. A single, central catalog on the master server tracks all resources (servers, on-site and off-site media, and tape devices) in the backup enterprise.
SRS architecture allows tape devices to be attached to UNIX, Windows, Linux, and NetWare servers, and NDMP-compliant Filers while requiring only a single, central resource catalog.
The master server handles all traffic requests from any machine on the SAN requesting a tape resource. If available, drive(s) are assigned immediately, or jobs are queued until the drives become available. Data travels over the high speed SAN, rather than over the LAN, reducing LAN traffic and decreasing backup and restore times.
- Dynamic Drive Sharing. Tape drives no longer need to be dedicated to individual servers. Rather, they can be assigned on the fly within the SAN.
- Optimized Device Selection. Backup Express can optionally release immediately for other jobs any unused drives and drives allocated to suspended jobs. In conjunction with early drive release, Backup Express prioritizes drives based on local SAN path and media availability.
- SCSI Reserve/Release.Devices on a SAN can be automatically SCSI reserve/released. This feature is supported for Windows, NetWare OES, SLES OES, Solaris, HP-UX, OSF, and Linux.
- LAN-Free Backup and Restore. Servers with substantial amounts of data can be backed up or restored over the SAN to free up LAN bandwidth for other applications.
- SAN and LAN Backup with a Single Master Server. SAN and LAN backups are tracked and managed with a single, central catalog. Multiple copies of the backup software are not required.
- Broad Platform Support. Backup Express is the only backup product that allows UNIX, Windows, Linux, NetWare OES and SLES OES servers, and NDMP-compliant Filers to be attached to a SAN while it maintains a single, central catalog for the entire enterprise.
- Hardware Independent. Backup Express SRS is compatible with SAN or SCSI technology and makes tape devices visible concurrently to multiple hosts and multiple operating systems.
- Device Monitoring. Centralized device
monitoring displays SAN device status in real time in the GUI.
Backup Express SRS provides dynamic drive sharing by managing
resource requests from a single location. A single, central
catalog on the master server tracks all resources (servers,
on-site and off-site media, and tape devices) in the backup
enterprise. SRS architecture allows tape devices to be attached
to UNIX, Windows, Linux, and NetWare servers, and NDMP-compliant
Filers while requiring only a single, central resource catalog.
