The users and system backup suite

This shell scripts running on the laptop/PC provide backup and restore capabilities by SSH via USB.

• USAGE: rfos-restore-backup.sh [ -v | -h ] [ -0|...|-4 ] [ /rootfs ]

• USAGE: rfos-rootfs-backup.sh [ -v | -h ] tarball [ /rootfs ]

• USAGE: rfos-user-backup.sh [ -h | -v ] [ /home/defaultuser ]

Thanks to this suite, it starts to become feasible to play with the root filesystem because it can be restored via a previous backup in a minute.

However, in some cases a simple rollback of a previous tarball backup cannot solve the issue (e.g.: into a service.d folder a faulty.conf, which is new and therefore will not be overwritten nor deleted). This limitation highlights the need for a recovery image that can provide an integral root filesystem restore from a full previous backup archive.

The SSH connetivity funtions

This script contains a variety of functions that aim to automatise as many cases as possible about SSH connectivity with the smartphone

• source sfos-ssh-connect.env

The suite has been recently updated to support a smoothless interaction with the new recovery image which allows to flash the partitions via SSH or do backup and restore of the rootfs filesystem and home users folders.

• tfish [ command ] - to use recovery telnet via USB on its default IPv4
• rfish [ command ] - to use recovery SSH via USB on its default IPv4
• ufish [ command ] - to use SSH via USB connection on its default IPv4
• wfish [ command ] - to use SSH via WiFi connection on its default IPv4
• afish [ command ] - to use the fast route IPv4 for SSH, updates IPv4 default
• sfish [ command ] - to use the previous route for SSH or it finds the fastest

scp support:

• s / afish [ scp ] -u $remote-dest-path $local-files - secure copy in upload
• s / afish [ scp ] -d $local-dest-path $remote-files - secure copy in download

extras:

• afish getip - set the fastest route IPv4 for establishing the SSH connection
• ufish tether - enable the tethering via USB when SFOS is in developer mode

The USB fastboot issues fixer

Well, the title is a little brave because this script does not solve all the problem that fastboot shows with the new USB hardware

• USAGE: fastboot-usb3fix.sh < 2 | 3 >

However, it contains interesting ways of doing things that will be nice to see in a little more elaborate approch: detach, fastboot, re-attach.
