jam preserves your data. you almost certainly want restic instead.
USAGE
jam [opts] <subcommand> [opts]
SUBCOMMANDS
integrity integrity check. for full effect, disable caching and enable read
comparison
key encryption key utilities
ls ls lists files in the given snapshot
mount mounts snap as read-only filesystem
rename rename allows a regexp-based search and replace against all paths
in the system, forked from the latest snapshot. See
https://golang.org/pkg/regexp/#Regexp.ReplaceAll for semantics.
revert-to revert-to makes a new snapshot that matches an older one
rm rm deletes all paths that match the provided prefix
snaps lists snapshots
store store adds the given source directory to a new snapshot, forked
from the latest snapshot.
unsnap unsnap removes an old snap

FLAGS
-blobs.max-unflushed 1000 max number of objects to stage
before flushing (must fit file
descriptor limit)
-blobs.size 62914560 target blob size
-cache file:///home/jt/.jam/cache where to cache things that are
frequently read
-cache.enabled true if false, disable caching
-config /home/jt/.jam/jam.conf path to config file
-enc.block-size 16384 default encryption block size
-enc.block-size-small 1024 encryption block size for small objects
-enc.key ... hex-encoded 32 byte encryption key,
or locked key (see jam key new/lock)
-log.level normal default log level. can be:
debug, normal, urgent, or none
-store file:///home/jt/.jam/storage place to store data. currently
supports:
* file://<path>,
* storj://<access>/<bucket>/<pre>
* s3://<ak>:<sk>@<region>/<bkt>/<pre>
* sftp://<user>@<host>/<prefix>
and can be comma-separated to
write to many at once
-store.read-compare false if true, compare reads across
all backends. useful for integrity
checking
