Compression tar.gz, problems with symbols and spaces in the name file?
A little background for clarity.
Make Bitrix backup of its standard methods, but when unpacking comes the error that the archive is broken. Understand that the fact that someone developed before site reason urge files with the name like "name (21.03.13, 13%3A37).php" and then a space and a comma and percent sign there. On these files it works like an archive.
The question is, where to read below to understand why this is happening. I.e. when archiving tar.gz problems arise when he stumbles on such files with symbols and spaces, or the problem is purely with Bitrix, who faced tell what the matter is or tell me where to read on this subject?
Honestly, this experience was not.
Well, first write a ticket to Bitrix.
Second alternatively you can create separate backups of files and database and try to restore. Not the fact that will work but for the sake of experiment - it is interesting.
