Burt: The Backup and Recovery Tool
نویسنده
چکیده
Burt is a freely distributed parallel network backup system written at the University of Wisconsin, Madison. It is designed to backup large heterogeneous networks. It uses the Tcl scripting language and standard backup programs like dump(1) and GNUTar to enable backups of a wide variety of data sources, including UNIX and Windows NT workstations, AFS based storage, and others. It also uses Tcl for the creation of the user interface, giving the system administrator great flexibility in customizing the system. Burt supports parallel backups to ensure high backup speeds, and checksums to ensure data integrity. The principal contribution of Burt is that it provides a powerful I/O engine within the context of a flexible scripting language; this combination enables graceful solutions to many problems associated with backups of large installations. At our site, we use Burt to backup data from 350 workstations and from our AFS servers, a total of approximately 900 GB every two weeks.

In recent years, routing has been the most focused area in ad hoc networks research. On-demand routing in particular, is widely developed in bandwidth constrained mobile wireless ad hoc networks because of its effectiveness and efficiency. Most proposed on-demand routing protocols are built and relied on single route for each data session. Whenever there is a link disconnection on the active ro...

Mobile sensor networks rely heavily on inter-sensor connectivity for collection of data. Nodes in these networks monitor different regions of an area of interest and collectively present a global overview of some monitored activities or phenomena. A failure of a sensor leads to loss of connectivity and may cause partitioning of the network into disjoint segments. A number of approaches have be...
متن کاملBackup Metadata As Data: DPC-Tolerance to Commodity File System
Backup Metadata As Data (MAD) is a user-level solution that enables commodity file systems to replicate their critical metadata and to recover from disk pointer corruptions. More specifically, it extracts disk pointers from file system and saves them as user data. When some data blocks become inaccessible due to pointer corruptions, Backup MAD restores access paths to them either by copying the...
متن کاملData Backup and Recovery Options
One of the most fundamental elements of any disaster recovery plan is data backup and recovery. If an IT staff lacks the ability to recover lost data following an incident or disaster, redundant hardware or hot sites are of only limited value. Relatively few years ago, planning a backup strategy was reasonably straightforward for the small-office-home-office (SOHO) and small-tomedium-sized-busi...
