[Plugin: BackWPup] Constant .zip and memory errors!

This plugin was awesome 3-4 updates ago! Sadly, its just a bunch of constant errors now.

1. try for make list of files to backup....
4915 files with 99.36 MB to backup

1. try to create backup zip (PclZip) archive...
Memory increased from 32M to 35M
[ERROR]Allowed memory size of 36700160 bytes exhausted (tried to allocate 9790544 bytes)

1. Script stop! Will started again now!
2. try to create backup zip (PclZip) archive...
Memory increased from 32M to 33M
[ERROR] Zip archive create error: PCLZIP_ERR_INVALID_ATTRIBUTE_VALUE (-20) : Invalid type array. String expected for attribute 'PCLZIP_ATT_FILE_NAME'

Any help would be amazing!
Thank you
