i got the impression from the manual that --disable-piped-streaming=true would reduce pointless overhead since i intend to use --throttle-upload=50kb anyway to keep traffic low. however it appears --disable-piped-streaming=true breaks restore!
it’s a bit confusing what happens upon completion of the backup. first i see “Remote backup verification completed”, then “Downloading…”, and, with --disable-piped-streaming=true, “Failed to process file duplicati-20200208T025245Z.dlist.zip.aes => Offset and length were out of bounds for the array or count is greater than the number of elements from index to the end of the source collection”.
while we’re looking, at the beginning of the run, it always complains “Failed to load process type Duplicati.Library.Common.IO.VssBackupComponents assembly /usr/lib/duplicati/Duplicati.Library.IO.dll, error message: Could not load type of field ‘Duplicati.Library.Common.IO.VssBackupComponents:_vssBackupComponents’ (1) due to: Could not load file or assembly ‘AlphaVSS.Common, Version=1.4.0.0, Culture=neutral, PublicKeyToken=959d3993561034e3’ or one of its dependencies. => Could not load type of field ‘Duplicati.Library.Common.IO.VssBackupComponents:_vssBackupComponents’ (1) due to: Could not load file or assembly ‘AlphaVSS.Common, Version=1.4.0.0, Culture=neutral, PublicKeyToken=959d3993561034e3’ or one of its dependencies.” but goes ahead and seems to work.
