Are all your back-ups showing the same problem?
Why did you save in docx-format?
I would alway use only odt-format until the very end.
let me paste here two experienced based recommendations:
Backups:
Very often I see questions on how to recover lost files. Better than attempting to recover lost data is prepare against the loss of data. To avoid a loss of a file these are 3 recommendations:
1 - Check the following LibO options: Tools > options > Load/Save > General
---- Save Autorecovery every x mins (the shorter the value the small a possible loss; I use 3 min)
---- Automatically save document too ( I don’t use this, because I regard the autorecovery function as excellent.)
---- Always create a backup copy (download and read the free of charge LibO guide to understand how this works)
2 - When I work more than a day on a file, I create additional daily back ups. I use the format “filename_yymmdd.ext” and I keep at least 1 previous version.
In case the file is extremely important and I work long hours non-stop, I add the actual time behind the date.
3 - Backup the HDD of your computer to an external HDD. External HDD in the range of 2-4 TB cost mostly less than 150 EUR. I do this almost daily and even backup external HDD onto another one.
When it comes to this topic this expression comes to my mind: “Fail to prepare is prepare to fail!”
Format:
In respect to MSO formats, I stay always until the end in LibO native formats and only create a MSO copy of the last saved version and still try to avoid the x-formats. Additionally I made the experience that a pdf-file is in most of my cases sufficient. Many people send out files in MSO or LibO or other formats when a pdf-file is sufficient. Depending on the situation you can even secure a pdf-file against copying and changes. The pdf-export function in LibO works very well. (I am using 4.3) (In 4.4 the x-formats should be better.)
In the case of presentations I am also often asked to provide a ppt or pptx copy as a fall back solution is something happens with my PC or connection of my own PC is not possible, etc. For this I always carry a USB stick with a portable LibO version on it and my presentation. All I need is PC to plug the USB stick and can run on LIbO my own presentation.
