Support

Dear Akeeba support,

We are experiencing an error when backing up our website.

First some background: our website backup is currently 4 .jpa files, the first is 1.2 GB and the second is 1.5 and the others are 2.5 GB.

We are aware that this is a large backup and we are wondering if we should use another method other than Akeeba.

the error message we receive is "akeeba Invalid header in archive file, part 1, offset 0". The content of these files are text and image files, no videos.

Any advice that you can give is greatly appreciated.

Best Regards, Admin

There isn't a lot I can tell you without the backup log.

All of the archive parts should be the same size, except for the last part, the jpa/jps file. So we definitely have something going wrong.

Please set your part size at 1999, that keeps the archive parts to under 2 Gb each. That 2 Gb is a magic number for PHP, it doesn't like numbers that big and can do strange things. It would absolutely be corrupt on a 32 bit server, but even on a 64 bit server we try to keep the parts under 2 Gb. That won't significantly increase your number of parts.

If lowering the part size doesn't fix the issue, please zip and post your backup log.

I see, i will change part size to 1999 and post the next log to see if there is any issue, thank you for your help
