There are several ways for different situations. I'll try to cover them all. So for deleted CouchDB documents you need to: 1. Make sure your document with this id is Deleted.

Get all the revisions of the deleted document. With this request: $db/$id?revs= true &open_revs=all Where $db is your CouchDB database name and $id is ...

I've decided to create a post with several recipes for commands I need to use daily. I use them from a Mac OS X Lion default console, except for some mac ports installed... Remote is special linux distribution. How do I Compress a Whole Linux or UNIX Directory?  You need to use tar command as follows (syntax of tar command): tar -zcvf archive-name.tar.gz directory-name Where, -z: Compress archive using gzip program -c: Create archive -v: Verbose i.e display progress while creating archive -f: Archive File name For example, you have directory called /home/garmoncheg/data and you would like to compress this directory then you can type tar command as follows: $ tar - zcvf data . tar . gz / home / garmoncheg / data / Above command will create an archive file called data.tar.gz in current directory. If you wish to restore your archive then you need to use following command (it will extract all files in current directory): $ tar - zxvf data . tar . gz Whe...
