Dear Bareos Users,
We are happy to present some exciting updates about our upcoming Bareos
24 release, planned for November 2024. Our team has been working hard to
bring you new features and improvements that will enhance your backup
and storage management experience. Here’s what you can look forward to:
*Dedupable Storage Backend*
A new storage backend will store backup data in a format optimized for
deduplication. This allows Bareos volumes to be deduplicated by storage
solutions and filesystems that support deduplication (like ZFS, VDO,
btrfs, etc.). The new '*bdedupestimate*' command-line tool can estimate
the deduplication potential of existing volumes, helping users optimize
storage use.
*Python Plugin in Separate Process*
Bareos supports plugins written in Python. Previously, running the
Python interpreter as a “subinterpreter” in the same process space
proved error-prone. The new release will run each plugin’s Python
interpreter in a separate process, solving all these problems.
*Just-in-Time Device Reservation*
In current versions, devices are reserved quite early during backup
jobs. There can be a long period between the reservation and the first
actual write operation. The device cannot be used for other tasks during
this time, even though it is not doing anything. With the new
just-in-time reservation feature, Bareos changes it by reserving a
device only when data is ready to be written. This feature significantly
improves the utilization of expensive tape drives.
*Support for WORM Tapes*
Bareos previously used a two-phase initialization for tape labels, which
was incompatible with WORM (Write Once Read Many) tapes. Bareos 24
introduces a single-write labeling procedure, allowing users to utilize
WORM tapes effectively.
*Windows Binaries Built Natively with MSVC Compiler*
The Windows binaries for Bareos have been cross-compiled on Linux until
now. With the new build system in Bareos 24, these binaries are built
using the Microsoft Visual C++ compiler, resulting in faster binaries
and better support for Microsoft toolchains.
