I’m trying to understand the logic of these “404” messages (file not found). Notice the times in the log lines:
New files identified, ok:
...
2019-05-07 09:36:46.649 TRACE PACK_START Packing [redacted]
2019-05-07 09:36:46.649 INFO PACK_END [redacted]
2019-05-07 09:36:46.649 TRACE PACK_START Packing [redacted]
2019-05-07 09:36:46.649 INFO PACK_END Packed [redacted]
Duplication check (I think) if these chunks related to these files exist in B2, obviously don’t exist, then returns the code 404, ok:
2019-05-07 09:36:47.650 TRACE BACKBLAZE_CALL [3] URL request 'HEAD https://f001.backblazeb2.com/file/[redacted]/chunks/96/026187e19bb68a45b521e9026844bd939893ba9c756e6151245eab7f864340' returned status code 404

Chunks don’t exist, then upload,ok:
2019-05-07 09:37:02.545 INFO UPLOAD_PROGRESS Uploaded chunk 1 size 644955, 75KB/s 00:00:12 58.1%

The sequence above is perfect.
But, in the same log (after the above sequence), there are other “404” messages:
2019-05-07 09:37:10.022 TRACE BACKBLAZE_CALL [1] URL request 'HEAD https://f001.backblazeb2.com/file/[redacted]/chunks/cc/e304ac3c6ca52bcdd29838269f9ec8581c988986c7308bf739f25b1841baff' returned status code 404

But no other record of Uploaded chunk
, and looking directly at B2, these chunks are there, and looks like been created in this backup run (by the timestamp).
And at the end of the log:
2019-05-07 09:37:45.216 INFO BACKUP_STATS Files: 24366 total, 1,219M bytes; 95 new, 2,073K bytes
2019-05-07 09:37:45.216 INFO BACKUP_STATS File chunks: 1036 total, 1,227M bytes; 2 new, 1,497K bytes, 1,458K bytes uploaded
2019-05-07 09:37:45.216 INFO BACKUP_STATS Metadata chunks: 7 total, 6,834K bytes; 7 new, 6,834K bytes, 2,398K bytes uploaded
2019-05-07 09:37:45.216 INFO BACKUP_STATS All chunks: 1043 total, 1,233M bytes; 9 new, 8,331K bytes, 3,856K bytes uploaded
Note: the check
command reports that everything is ok, all chuncks of all revisions are in storage.
So I have 9 “404” messages but only 2 “upload” messages. I didn’t understand…
