Suddenly I needed to restore a backup, only to discover that all backup files created are corrupt! The ICDB backup tool will not restore them, and testing the files in 7zip reports errors. Currently using VX.1.2 - Update 19.
Snippet from the log below.
[2018-04-30 12.38.32] Successfully created [AutoSave] backup [2018-04-30 12.38.19 - auto.zip] requested by [id removed].
[2018-04-30 12.57.44] ERROR: Cannot decompress Project Backup archive. [User] backup [2018-04-30 12.35.52 - user.zip] will not be restored.
What can cause this? I also now tried to verify backups created in another project, and I see the same there, the ZIP files are corrupted. Tested also a few backup created by PCs of colleagues using the same version of applications, but those files all seem OK.
We have encountered this strange behavior too. We solved this by redoing the backup once again and the second time the zip was usually ok.
But not always.
I have not digged into this, but I have seen what you described. You are not alone.
Please let me know if and when you solve this issue.
