What is a BCK file

BCK files mostly belong to OpenVMS by Hewlett Packard Enterprise. BCK extension files are the backups files for complete volumes of files in the VMS, VAX or VMS, Alpha operating systems for industrial grade servers from the eighties and nineties of the twentieth century. Main purpose of BCK file is to provide protection against major data-loss and data damage. User can easily restore data using BCK files. VMS systems were used to manage commercial servers which were developed by Digital Equipment. User can archive backup data in form of recordings on magnetic tapes or hard drives. The OpenVMS replaced both VAX-11/VMS and VAX/VMS system.

BCK file format:

To view or edit BCK files you need to know the file format, because it determines how the data in this file is stored. The file format can be determined based on the file extension and the signature (the first few characters of a file). However, different programs can use the same file extension, and file extensions can be assigned incorrectly. Knowledge is power - this also applies when dealing with unknown or faulty files. Our analysis of the BCK files produces the following result:

The BCK file type is a very commonly used file extension and has no uniform or dominant file format. But the following two file formats are common:

• 15% of all BCK files use the ZIP format, so several files are combined and compressed into one BCK file. The average file count is 108 with most BCK files containing between 1 - 230 compressed files. You can see the included files and images by renaming the file extension to .zip and then double-clicking it. A typical file size is 1 MB. A common filename is bdetpos-20180601.bck. Such BCK files store data about admba, backup, etpos, connect and edge.
• 9% of all BCK files have the same signature TAPE. The contents of these files cannot be read by a human; only a computer program can interpret the data. A typical file size is 110 MB. Several words can almost always be found in the files, e.g. TAPE, Microsoft SQL Server, SPAD and RAID.

All other BCK files (76%) have different formats, such as TNC Packed Backup, JetDB, EXE, SQL, ewogICAgI, All, BCK, ELIC, From, MSSQLBAK, pia and CFV. The category is todate, date, configuration, build, dark, walletbackup, pressure, blood or data. Drag & drop your file here to see the file format and a preview of your BCK file!
