Please write your opinion about the idea.

Good day!

Recently I had an idea to use SVN for backup of site files (meaning not saving source files, but user content / logs / etc).


')

I see the following benefits:

• SVN is a free tool;
• Ease of backup;
• The ease of restoring backup (and, any version and on any computer);
• Only backup items that have been modified are created;
• Comfortable work with history;
• Convenient configuration of the contents of the backup (what to include in the backup, and what - no);

I also see the following "minuses" of this approach:

• The site will occupy 2 times more space, because SVN keeps copies of files for its work.
• Hole in security ( http://habrahabr.ru/blogs/infosecurity/70330/ , http://habrahabr.ru/blogs/infosecurity/84357/ )

Please write in the comments your opinion:
- What other disadvantages do you see in creating backups using SVN?
- Ways to eliminate deficiencies.
- Suggestions for creating backups in other ways.

Ps.
On the Internet, there are mostly descriptions of which commands you need to write in bat-files so that the site can be backed up in SVN. For some reason, there is almost no discussion of advantages and disadvantages.
I found several references to such discussions, but it is impossible to draw an unequivocal conclusion on them.

UPD:
- When backing up using SVN, the rights to folders are not saved (thanks for the lack of thanks alexey_uzhva )

UPD2:
Although the topic was preserved, it still turned out to be very useful for me.
So far I plan to get to know Bacula closer - judging by the reviews, a powerful and convenient tool for backups.

Thank you all for the discussion!
