		<description><![CDATA[Today, I released new version of OmniPITR &#8211; 0.5.0. This new version has one important new feature &#8211; which is so called &#8220;direct destination&#8221; for backups. What it means? What it does? How it helps? Let&#8217;s see&#8230; Let&#8217;s assume you have remote destination for backups, something like: $ omnipitr-backup-master ... -dr gzip=storage.host:/path/to/store/backups ...

		<description><![CDATA[I had this interesting case at work. We have imports of objects. Each object in import file has its &#8220;ID&#8221; (which can be any string). Same &#8220;ID&#8221; is in database. So the idea is pretty simple &#8211; we can/should check how many of IDs from import were in database. Unfortunately &#8211; we&#8217;d rather not really [...]]]></description>

So, I have a directory structure: /some/path/imported/DATE/TIME/file, where DATE is date of importing, in format YYYY-MM-DD, and TIME is time of importing, in format HHMMSS.
