2) SQLite
SQLite is only really there for testing purposes and the odcumentation
makes it very clear that it's not recommended for production systems.
6) Does not track deletions between full backups.
Show me more than 3 (quite expensive) commercial packages which do this.
This is a common failing of almost all backup systems and is hardly
exclusive to Bacula.
Restoration will uncover
deleted files. Over a long period of time this could lead to restorations
that exceed the space on the partition that is being restored especially for
sites that have long retention periods and heavy tunover.
Do Full backups more often. By policy we only run long cycle times on
filesystems which are mostly append-only.
As far as restoring a snapshot of any particular instant in time goes, I
suspect the only practical way of doing this would be to generate and save
a filesystem index at each backup (this wouldn't be difficult, but would
be overkill in 90% of sites)
As always, the code is opensource and if you feel you can improve it, then
by all means, chip in.
For our site (~20TiB of astronomical and space probe data), the practical
alternatives to Bacula are commercial solutions with pricetags starting
somewhat past $10,000 and going upwards from there.
As it is, Bacula is winning many converts from lesser-specified commercial
offerings, as well as many other OSS offerings which are more difficult to
operate.
WRT the comments about the configuration files, the single biggest problem
with them is not their complexity, but the spaghetti nature of the
default/example definition files. I intend working on this shortly, as
with something like 60 backup sets to manage, it's becoming a handful.
