This service will never run automatically, but it encapsulates the
necessary logic and configuration to run a restore of the latest
archive, and allows to hook more specific logic, such as loading
a database dump, via `postStart`.
A new option `explicitSymlinks` will set `-H` when creating an archive.
This option makes tarsnap follow any symlinks specified explicitly on
the commandline, but not any found inside the file tree.
A new option `followSymlinks` will set `-L` when creating an archive.
This option makes tarsnap follow any symlinks found anywhere in the file
tree instead of storing them as-is.
When the znapzend module was enabled for the first time with pure =
true; then the list of previous entries is empty, but xargs still tried
to execute a znapzendzetup delete command with no arguments, which made
it fail
This enables znapzend users to specify its full configuration through
NixOS options, without ever needing to use the stateful `znapzendzetup`
command.
This works by running znapzendzetup with the specified config in
ExecPre, just before the znapzend daemon is started.
There is also the `pure` option which will clear all previous znapzend setups,
making it as stateless as can get, as only the setup declared in
configuration.nix will be persisted.
* Grants enough privileges to the configured user so that it can run
mysqldump.
* Adds a nixos test.
* Use systemd timers instead of a cronjob (by @fadenb).
* Creates a new user for backups by default, instead of using mysql
user.
* Ensures that backup user has write permissions on backup location.
* Write backup to a temporary file before renaming so that a failed
backup won't overwrite the previous backup, and so that the backup
location will never contain a partial backup.
Breaking changes:
* Renamed period to calendar to reflect the change in how to
configure the backup time.
* A failed backup will no longer result in cron sending an e-mail --
users' monitoring systems must be updated.
Resolves #24728
* the major change is to set TARGETDIR=${vardir}, and symlink from
${vardir} back to ${out} instead of the other way around. this
gives CP more liberty to write to more directories -- in particular
it seems to want to write some configuration files outside of conf?
* run.conf does not need 'export'
* minor tweaks to CrashPlanDesktop.patch
- add missing types in module definitions
- add missing 'defaultText' in module definitions
- wrap example with 'literalExample' where necessary in module definitions
Two concurrent tarsnap backups cannot be run at the same time with the
same keys - completely separate sets of keys must be generated for each
archive in this case, if you want backups to overlap.
This extends the archives attrset to support a 'keyfile' option, which
defaults to /root/tarsnap.key like the top-level attribute.
With this change, if you generate two keys with tarsnap-keygen(1) and
use each of those separately for each archive, you can backup
concurrently.

Tarsnap locks the cachedir during backup, meaning if you specify
multiple backups with a shared cache that might overlap (for example,
one backup may take an hour), secondary backups will fail. This isn't
very nice behavior for the obvious reasons.
This splits the cache dirs for each archive appropriately. Note that
this will require a rebuild of your archive caches (although if you were
only using one archive for your whole system, you can just move the
directory).
