I have set a cron job for each of my sites which starts a full backup every day. The backup files are stored remotely, on my Amazon S3 account. This was working quite ok for a long time, but now I noticed that on one site the .jpa file is missing in all backups that were made after a given date. I have about 60 sites running and I did not yet find another site with this issue but did not check them all.
The jpa is also missing when I start the backup from the back end using the same profile (remote storage on S3).
When I start a backup from the back end using the default profile (storing the backup on the live site disk space) then the result is ok.
Hope you can help me find the solution, as these back ups are useless now. A log file is included.
Thanks, Frits
