![]() ![]() Backup schemes may include dry runs that validate the reliability of the data being backed up. Additional techniques apply to enterprise client-server backup. The process can include methods for dealing with live data, including open files, as well as compression, encryption, and de-duplication. There are also different ways these devices can be arranged to provide geographic dispersion, data security, and portability.ĭata is selected, extracted, and manipulated for storage. There are different types of data storage devices used for copying backups of data that is already in secondary storage onto archive files. An information repository model may be used to provide structure to this storage. ![]() The data storage requirements can be large. Ī backup system contains at least one copy of all data considered worth saving. Backups provide a simple form of disaster recovery however not all backup systems are able to reconstitute a computer system or other complex configuration such as a computer cluster, active directory server, or database server. Backups can be used to recover data after its loss from data deletion or corruption, or to recover data from an earlier time. The verb form, referring to the process of doing so, is " back up", whereas the noun and adjective form is " backup". In information technology, a backup, or data backup is a copy of computer data taken and stored elsewhere so that it may be used to restore the original after a data loss event. For other uses, see Backup (disambiguation). You are discouraged from using UI-side overrides, because it's cleaner to let the engine manage new job defaults.This article is about duplicate data in computer systems for data recovery. The difference here is that the former will clear the default exclusions list and the latter will preserve it. The engine looks for and loads \engine\backup-override.iniĭO NOTE that #2 and #3 require release 78.19 or newer.Īdditionally, the UI will also do legacy processing of new backup settings by loading overrides either from \ui\backup-template.ini or The engine looks for and loads \engine\backup-template.iniģ. The engine first sets a new job to hard-coded defaults.Ģ. Similar mechanism can be used to override values in a template used to initialize new backup jobs.ġ. #2 provides a way to apply an override to all jobs at once and #3 is a way to patch a specific job.ĭO NOTE that #2 requires release 78.19 or newer. The engine looks for and loads \engine\backup-00xx\override.ini The engine looks for and loads \engine\backup-override.iniģ. The engine reads \engine\backup-00xx\settings.iniĢ. When a job is loaded, its settings are read and then patched as follows:ġ. Similar mechanism is used for overriding backup job settings. Overriding settings - Existing backup jobs These files are never modified by the program. Override files are loaded immediately after primary ini files. In addition to directly editing bvckup2-engine.ini and bvckup2-ui.ini, you can also modify settings in these files by creating a so-called "override" ini file and placing your changes there. Whenever you tell the app to download and install the update (in response to the "New version available" prompt), the update is downloaded and stored in this directory. This folder host the UI configuration (window state, position, update check status, etc.) in a file called. \engine\bvckup2-engine.ini - the engine configuration \engine\bvckup2-email.txt - a text file with the email alert template \engine\bvckup2.lic - a text file with your license ![]() Now, climbing back up to \engine level, there are several files of note. This folder can be deleted if needed, just keep in mind that doing so will cause the app to re-copy files in full once they are modified at source. This will be the largest part of each backup's configuration, potentially with a lot of files, taking up non-trivial amount of disk space. The "delta" sub-folder contains binary files with per-block checksums for all files in the backup that were copied with the delta copier. Snapshot.dat - binary file with the snapshot of the destination Settings.ini - the backup configuration, all of it The engine folder contains settings and the state data of all configured backups, each in its own sub-folder, starting with backup-0001:ĭelta\ - sub-folder with checksum files from delta copierīackup.log - plain text file with the log of the backup jobīackup.tdb - binary index file of the above, used internally These capture the context of certain operations in the app and they are primarily needed for troubleshooting issues with tech support. There will likely be an assortment of other log files, e.g. \bvckup2.ini - settings shared between the engine and the UI \updates - a folder with all previously downloaded app's updates \engine - a folder with the engine data (see below) ![]()
