Post date: October 6, 2008, 21:10 Category: System Views: 3815 Comments
Tutorial quote: rsnapshot is a filesystem backup utility based on rsync. Using rsnapshot, it is possible to take snapshots of your filesystems at different points in time. Using hard links, rsnapshot creates the illusion of multiple full backups, while only taking up the space of one full backup plus differences.

Storing Files/Directories In Memory With tmpfs

Post date: December 9, 2008, 12:12 Category: Miscellaneous Views: 2927 Comments
Tutorial quote: You probably know that reading from RAM is a lot of faster than reading files from the hard drive, and reduces your disk I/O. This article shows how you can store files and directories in memory instead of on the hard drive with the help of tmpfs (a file system for creating memory devices). This is ideal for file caches and other temporary data (such as PHP's session files if you are using session.save_handler = files) because the data is lost when you power down or reboot the system.

Flip - Convert text file line endings between Unix and DOS formats

Post date: March 2, 2009, 07:03 Category: System Views: 2698 Comments
Tutorial quote: This program converts line endings of text files between MS-DOS and **IX formats. It detects binary files in a nearly foolproof way and leaves them alone unless you override this. It will also leave files alone that are already in the right format and preserves file timestamps.User interrupts are handled gracefully and no garbage or corrupted files left behind. ‘flip’ does not convert files to a different character set, and it can not handle Apple Macintosh line endings (CR only). For that (and more), you can use the ‘recode’ program (package ‘recode’).

- IO Test: read, write, rewrite, and seek in three 1GB size files.
- Load: all tests are starting with 0 cpu load. Load was then measured every 2 seconds for the duration of the test and averaged over all measurements.
