.SH SYNOPSIS
.nf
\fBobsync\fP [ \fIoptions\fP ] \fIsource\-url\fP \fIdestination\-url\fP
.fi
.sp
.SH DESCRIPTION
.sp
\fBobsync\fP is an object syncrhonizer tool designed to transfer objects
between different object storage systems. Similar to rsync, you
specify a source and a destination, and it will transfer objects
between them until the destination has all the objects in the
source. Obsync will never modify the source \-\- only the destination.
.sp
By default, obsync does not delete anything. However, by specifying
\fB\-\-delete\-after\fP or \fB\-\-delete\-before\fP, you can ask it to delete
objects from the destination that are not in the source.
.SH TARGET TYPES
.sp
Obsync supports S3 via \fBlibboto\fP. To use the s3 target, your URL
should look like this: \fBs3://host\-name/bucket\-name\fP
.sp
Obsync supports storing files locally via the \fBfile://\fP target. To
use the file target, your URL should look like this:
\fBfile://directory\-name\fP
.sp
Alternately, give no prefix, like this: \fB./directory\-name\fP
.sp
Obsync supports storing files in a RADOS Gateway backend via the
\fBlibrados\fP Python bindings. To use the \fBrgw\(ga target, your URL
should look like this: \(ga\(gargw:ceph\-configuration\-path:rgw\-bucket\-name\fP
