Comparison

Salvo vs JetBackup

Feature by feature, with the date and source of every row. JetBackup is a mature product; we also show what it does that we don’t yet. Salvo is in development: where it says “planned”, it doesn’t exist yet.

Status of an account with a problem

JetBackupCompleted, Partially Completed or Failed; the reason is in the log. On the observed night, 16 of the 17 “partial” accounts had mailboxes without a password (143 mailboxes), a normal state.

SalvoSays which mailbox, database or file was left out and why, and tells a normal state apart from a real error. In development.

MySQL database dumps

JetBackupmysqldump with --skip-lock-tables, without --single-transaction.

Salvomysqldump with --single-transaction; a dump that doesn’t finish is treated as a failure. MyISAM tables are locked only while they’re copied.

How switching will work Imports JetBackup’s destinations, jobs, schedules, retention and filters (in development: today it reads and simulates).Runs in parallel, in its own folder on the same destination, while you compare both.At switch-over, stops and disables JetBackup’s services without uninstalling. You can turn it back on until you confirm removal.Reads and restores old JetBackup backups, starting with the SSH/local format. These last three steps are planned.
