git-annex 10.20230126-3 (s390x binary) in ubuntu mantic

 git-annex allows managing large files with git, without storing the file
 contents in git. It can sync, backup, and archive your data, offline
 and online. Checksums and encryption keep your data safe and secure. Bring
 the power and distributed nature of git to bear on your large files with
 git-annex.
 .
 It can store large files in many places, from local hard drives, to a
 large number of cloud storage services, including S3, WebDAV,
 and rsync, with dozens of cloud storage providers usable via plugins.
 Files can be stored encrypted with gpg, so that the cloud storage
 provider cannot see your data. git-annex keeps track of where each file
 is stored, so it knows how many copies are available, and has many
 facilities to ensure your data is preserved.
 .
 git-annex can also be used to keep a folder in sync between computers,
 noticing when files are changed, and automatically committing them
 to git and transferring them to other computers. The git-annex webapp
 makes it easy to set up and use git-annex this way.
