Re: [Duplicity-talk] signature file size

[Kenneth Loafman]

The sigtar size is dependent on the total size of the backup actually done.  You have the perfect case for a change to --max-blocksize.  It is currently set to be 2048, but can be increased on the command line.  Please read the man page via 'man duplicity' for more details.

Hello,
I am using duplicity in order to backup 4 large files. Once a week I do
a complete backup on a removable device and then move the device
elsewhere.

The difftar files are 500mb each and they are about 2300 in number. The
resulting signature file is more than 700Gb in size.

Is there any way to reduce the signature file size? Does it depends on
the data backed up or on the difftar file? Would its size change if I
set a different size for difftar files? Or, If I change a different GPG
signature algorithm?

Thank you,
Giuseppe
