Backups Failing – No Reason Given

  • Each backup attempt – auto or manual – is failing and I’m not sure why. The fail message says “no error message was logged.” Here’s the complete log entry:

    Hi,

    This is the symptom:
    Only 70384 of 311296 bytes were written. (2147413216 bytes already written.)

    I am guessing that the cause is the backup file is too big for the server’s filesystem, some filesystems have a 2GB file size limit and this has just breached that, failing the write. In fact, even if the backup worked, if it was over 2GB it wouldn’t be readable due to way ZIP works.

    If we take the already written and add on the 70384 that was just written, then divide by 1024 three times, we get 1.99999996 GB. Pretty much 2GB.

    We are going to improve the error messages in time to hint towards this, and prevent it going over 2GB so as to prevent the unreadable ZIP files (or maybe use new ZIP format to allow bigger sizes but that’s a bit more work to do). But best thing to do is to reduce the backup size by excluding some data on the General Settings screen.

    Regards,

    Jason
