In the announcement of TKL version 12, there's a mention of version 1.2 of TKKLBAM being included....and I'm particularly interested in this option:
Multipart parallel S3 uploads dramatically speed up how long it takes to upload backup archives to the cloud. Dial this up high enough and you can typically fully saturate your network connection. http://www.turnkeylinux.org/blog/turnkey-12
In Github I found a mention of the S3-parallel-uploads flag (https://github.com/turnkeylinux/tklbam/blob/master/docs/tklbam-backup.txt), but I've tried to insert it in the overrides for TKLBAM from within Webmin, and no matter how I tweak the line I just can't get it to go - I get the following error when I try to run a simulated backup:
> tklbam-backup --simulate
Traceback (most recent call last):
File "/usr/bin/tklbam-backup", line 366, in <module>
File "/usr/bin/tklbam-backup", line 152, in main
conf = Conf()
File "/usr/lib/tklbam/conf.py", line 141, in __init__
self.overrides = Limits.fromfile(self.paths.overrides)
File "/usr/lib/tklbam/conf.py", line 45, in fromfile
raise Error(`limit` + " is not a legal limit")
conf.Error: "--s3-parallel-uploads=2" is not a legal limit
I've tried it with quotes, without quotes, without the double dash, with the double dash....
In looking at the source at /usr/bin/tklbam-backup I see that it does indeed mention this variable, so I'm pretty sure I've got the latest version.
