Installation and updates

One command installs Salvo, and the same command updates it.

Requirements

• root access;
• an x86_64 server (other architectures are refused);
• curl;
• the download credentials, sent with the beta invitation.

Install

root@server

curl -fsSL -u USER:PASSWORD https://salvobackup.com/download/install.sh | sh -s -- -u USER:PASSWORD

The script:

1. downloads the latest version and checks its sha256; if it does not match, nothing is installed;
2. puts the salvo binary in the state folder, /var/lib/salvo (use --state DIR only for another folder);
3. detects the control panel and installs the screen:

Panel	What is installed
cPanel	WHM › Plugins › Salvo Backup (root only)
DirectAdmin	the admin plugin and a local service on 127.0.0.1
none	command line only

It does not touch anything outside Salvo. The binary is not added to the PATH: call it as /var/lib/salvo/salvo.

Reinstall from scratch

--clean removes the installation that exists (the same as Remove Salvo, including the vault copy kept in /root) and then installs:

root@server

curl -fsSL -u USER:PASSWORD https://salvobackup.com/download/install.sh | sh -s -- -u USER:PASSWORD --clean

Turn on the schedules

Salvo has no permanent service: scheduled backups run when cron calls schedule-run every minute (one runner at a time; a missed time is caught up if it passed less than agenda_janela_horas ago, 12 hours by default).

/etc/cron.d/salvo-backup

* * * * * root /var/lib/salvo/salvo schedule-run --state /var/lib/salvo

Create it only when you decide to turn the schedules on (see First steps).

Update

Run the install command again, or, on the server:

root@server

# only shows if there is a new version
/var/lib/salvo/salvo self-update --check
# updates (sha256 checked, panel screen reinstalled)
/var/lib/salvo/salvo self-update
# the installed version
/var/lib/salvo/salvo version

Remove
