Isn’t that what the RecoveryTool’s recompress option does?

----

Duplicati.RecoveryTool.exe list <localfolder> [version] [options]



Lists contents of <localfolder> backups.

Version can be either a number, a filename or a date. 

If [version] is omitted a list of backup versions are shown, if [version] is supplied, files from that version are listed.

Use the filters, --exclude, to show a subset of files.







Recompress

----

Duplicati.RecoveryTool.exe recompress <targetcompression> <remoteurl> <localfolder> --reupload --reencrypt [options]



1) Downloads whole remote storage to <localfolder>.

2) Recompress from existing compression type to <targetcompression>

3) If --reencrypt is supplied, again reencrypts using same passphrase (needs to be decrypted for compression type change)

4) If --reupload is supplied, files with old compression are deleted and recompressed files are uploaded back to remote storage (it is recommended to take at least temporary copy of remote storage before enabling this switch)



If --reupload is supplied it is advisable to specify --reencrypt for perfect security.
