In computing, off-site data protection, or vaulting, is the strategy of sending critical data out of the main location (off the main site) as part of a disaster recovery plan. Data is usually transported off-site using removable storage media such as magnetic tape or optical storage.
The company's second funding round, led by TPG Capital, raised $100 million in August 2015. [7] In March 2018, the company had an initial public offering (IPO) in which it raised $192 million. [8] [9] The company is traded on the Nasdaq using the symbol ZS. [10] Zscaler stock was added to the Nasdaq-100 index on December 17, 2021. [11]
The Data Domain Operating System (DD OS) is the intelligence behind Data Domain systems that makes them the industry’s most reliable and cloud-enabled protection storage. The second Dell EMC offering is Avamar: this unit de-duplicates data at the source via an agent on the host which offers savings on bandwidth utilization during backup.
ZScaler tunnel 2.0 for ZScaler Internet Access (ZIA) uses DTLS for tunneling. ZScaler Private Access (ZPA) does not support DTLS [39] F5 Networks Edge VPN Client uses TLS and DTLS. [40] Fortinet's SSL VPN [41] and Array Networks SSL VPN [42] also use DTLS for VPN tunneling. Citrix Systems NetScaler uses DTLS to secure UDP. [43]
Identification, classification and protection of system resources; Maintenance of access rights to the protected resources (access control) Controlling the means of access to protected resources; Logging of accesses to a protected system and protected resources (auditing) RACF establishes security policies rather than just permission records ...
True continuous data protection, in contrast to "snapshots", has no backup schedules. [5] When data is written to disk, it is also asynchronously written to a second location, either another computer over the network [6] or an appliance. [7] This introduces some overhead to disk-write operations but eliminates the need for scheduled backups.
Thus, a representation that compresses the storage size of a file from 10 MB to 2 MB yields a space saving of 1 - 2/10 = 0.8, often notated as a percentage, 80%. For signals of indefinite size, such as streaming audio and video, the compression ratio is defined in terms of uncompressed and compressed data rates instead of data sizes:
The host protected area (HPA) is an area of a hard drive or solid-state drive that is not normally visible to an operating system. It was first introduced in the ATA-4 standard CXV (T13) in 2001. [ 1 ]
