Uploading the File Recovery Manager

Trilio allows you to view or download a file from the snapshot. Any changes to the files or directories when snapshot is mounted are temporary and are discarded when the snapshot is unmounted. Mounting is a faster way to restore a single or multiple files. To mount a snapshot follow these steps.

Trilio ships with a ubuntu based file manager image. This image includes a web based file manager application that helps with browsing and download files when snapshot is mounted. Before you create a File Manager instance, File Manager (a.k.a Recovery Manager) image needs to be uploaded to the Glance. The cloud administrator can upload the image to Glance and mark the image public so that every tenant will have access to the image. File Manager image includes a qemu guest agent. Trilio data mover communicates with the qemu agent to map backup images and discover file systems in the backup images. Since the file manager image includes qemu guest agent, the image should be uploaded to glance with property hw_qemu_guest_agent=yes so Nova will create a qmp channel when creating an instance from this image. Trilio horizon plugin uses a special property tvault_recovery_manager, when set to yes it will filter out instances that don’t have this property. If a tenant has a huge number of instances, setting this property on the image will help Trilio horizon plug-in present only the instances whose image has this property. In this release we only support launching File Manager instance with virtio bus so please set hw_disk_bus to virtio. Use the following command to upload the image to Glance and mark it as public image and set the property.

--file <File Manager Image Path> \

--disk-format qcow2 \
