New Qemu Backup Architecture and API

on YouTube ↗11m

" summary

Claims a new QEMU backup architecture and API that implements a block-driver-based, point-in-time consistent backup path with bitmap-based incremental external backup and a public block filter API. It wires into QEMU block drivers so active disks are captured without VM pause, supports starting backups from disk images, cloning and caching, and offers transaction-like semantics for backup jobs. A working prototype in Virtuozzo is demonstrated, addressing incompatibilities of old filters and improving incremental efficiency.
