Frequently Asked Questions

Do you have the capability to handle large data sets?

Web-Surveys.Net - Online Research, Reporting and Business In...
Yes. Web-based survey data is collected/stored and compiled into an encrypted data file. There are virtually no limitations in terms of the number of cases our systems can handle in terms of the volume of survey traffic, and/or in the management/analysis of data files. On more than one occasion, we have managed data sets as large as 1,000,000 records comprised of over 500 variables.

How fast is rdiff-backup? Can it be run on large data sets?

rdiff-backup FAQ
rdiff-backup can be limited by the CPU, disk IO, or available bandwidth, and the length of a session can be affected by the amount of data, how much the data changed, and how many files are present. That said, in the typical case the number/size of changed files is relatively small compared to that of unchanged files, and rdiff-backup is often either CPU or bandwidth bound, and takes time proportional to the total number of files.

How large are the data sets you offer?

GLCF: FAQ
Many of our files are served as binary files. This is due to the fact that support for binary raster files is relatively standard across platforms and image processing packages. Usually one will need the pixels and lines and relevant georeferencing information. This may be found in the metadata file issued with all data downloaded from one's Workspace. If the data was served from a project-specific page, the metadata is either included in the download or is listed on the page itself.
