Amazon S3 upload fails

Post by garciacarral »

Hi all,

First time here. I set up an Amazon S3 destination (AWS account already working for a long time). The Backup4All test works, but the real backup fails. The transfered file is about 100GB and the log shows:


[25/06/2018 11:03:48] Shadow copy created for drives E:

[25/06/2018 11:03:48] Archiving files to

[25/06/2018 20:25:05] Testing content of zip E:\Temporal\Softland\Backup4all 7\B47B114HD219952HU7V909W5C8E1\
Backup aborted. Reason:
Cannot upload file "E:\Temporal\Softland\Backup4all 7\B47B114HD219952HU7V909W5C8E1\" to "/alviscrm/Backup CRM/" (Amazon S3). Bad Request - Part number must be an integer between 1 and 10000, inclusive (InvalidArgument) (400)
Next scheduled backup: 01/07/2018 22:00:00
Backup aborted after 13:27:18 hour(s) at 26/06/2018 0:30:24 with 1 error(s), 0 warning(s)


I understand that the chucks size / number must be changed to comply with the limits of Amazon S3 but I see not way to change that on Backup4All.
