- Record folders without files in the meta record of a snapshot and restore them (#27)
- Errors writing to the restore directory stop the restore, also with --salvage
- Resume: check the folder before skipping, clean temporaries in folders that are complete
- Clean only read-ahead folders of our own; refresh the lease on skipped files
- Drop tables a failed database restore created; keep --salvage from calling a restored database fresh
- Retry a pack that fails to open on the storage (SMB)
- Without cron, running backups take turns from the open page
- Bin: read in parts with a counter and progress bar, show read errors, refresh when a run ends
- The admin page and backup:status warn when background jobs do not run on a
system cron, or the cron stopped, with a link to how to set one up.
- Without a working system cron, the open admin page moves a running backup
forward through /api/tick, a short step per poll.
- The database phase shows the tables dumped ("db: 47/183 tables"); a backup
that has not moved for 15 minutes says it is waiting for background jobs.
- The trash of restore points is on a tab of its own, Bin.
- New screenshots; changelog and plan for 1.0.2.
- Admin page: an optional label (at most 100 characters) for a backup started with "Back up now";
an (i) by "removed by retention policy" in the trash that explains what it means and until when
the restore point can be brought back. backup:trash says the same below its list.
- backup:status, backup:list, backup:trash and backup:browse show times in the zone of the daily
schedule and name it, instead of the server's UTC.
- backup:restore --to-directory of a file restored nothing: the path got a "/" appended.
- A restore removes "<name>.ngb-restore-<hex>" temporaries that a stopped restore left in the
folders it writes to.
- Roadmap: the cron warning (#13), reading ahead from S3/SMB and --salvage move to 1.0.2.
On S3, index files and the tree segments read back when a snapshot is
written are fetched 16 at a time through the storage's S3 client
(IBackend::getRanges(), getMany()). Blobs that follow each other in a pack
are read as one range on every location. The snapshot is written in a step
of its own and the run shows "commit" meanwhile. On a 1 TB production
repository the check went from about 4 hours to 3.5 minutes.
backup:status and the web interface list the runs of the last 7 days,
running ones and at least the newest 5; --all / "Show older runs" list
all. Durations of a day or more show the days.
A run only showed "running (files)", which says nothing during a backup
of a terabyte. The files phase now records an expected size on its first
step: the previous snapshot's size, or for a first backup the users'
files, versions and trash from Nextcloud's file cache (approximate, shown
with a ~). The web interface and occ backup:status show the share of it
done so far, including a large file that is still being read; it stays
below 100% until the run finishes.
A changed password or host name could only be handled by adding a new
location, which starts an empty repository and, with a retention lock at
the provider, keeps the old one billed. Edit now changes a location in
place (web interface and occ backup:target:edit). The settings are only
saved when they lead to the same repository; a failed connection and a
missing repository give separate errors, and the folder is not created
while checking. Stored passwords are never sent to the browser: an empty
password field keeps the stored value.
addTarget requires a recent password confirmation, but the form never
asked for one. Within 30 minutes of logging in that went unnoticed; after
that, adding a location failed with a bare 403.
Add three screenshots (backups, restore, settings) taken on a demo
instance, plus website, repository and the HOWTO as admin documentation
in info.xml.
Fixes found while taking them:
- the "new folder" restore option lost "<date>" (l10n sanitizes it as
a tag); show the folder name pattern via a placeholder instead
- the restore-point dropdown cut off the time
- passphrase actions stacked vertically in the slot table
- HOWTO: SFTP example used "sftp::password", the auth mechanism is
"password::password"
Move backup locations onto the Settings tab next to the key setup,
since adding one is a one-time step like the key, not daily use. The
"Backup and restore" tab points there when no location exists yet.
The restore-point dropdown relied on NcSelect's get-option-label,
which it does not render for the selected value, so no date showed.
Precompute a displayLabel per snapshot and select on that instead,
the same way the location dropdown already does.

Show the date of the restore point a restore run used, both in the
backup history table and when confirming a restore. Split the admin
page into a "Backup and restore" tab (locations, backups, restore)
and a "Settings" tab (key, slots, recovery kit), so daily work no
longer sits behind the key setup at the top of the page.

- after each successful backup the stored size is recorded; at 80% of a
location's limit administrators get a notification (once a day)
- locations list shows stored size and limit; the add form has a
'maximum size' field that explains that empty means unlimited and
billed by the provider; PUT /api/targets/{id}/limit (password
confirmation)
Tested on NC34 with the OVH test bucket: a backup above the limit stops,
a successful one at 81% sends the warning.
- one locking protocol per location: backup steps and restores hold a
shared lock, prune and untrash an exclusive one and refuse while any
run (backup, restore, export) exists; starting a backup checks and
creates the run under the exclusive lock, closing the race with prune
- snapshot entries are validated when read (relative path without '.',
'..', NUL, backslash or control characters); raw restore also checks
that the resolved directory stays below the target; the restore API
and service accept canonical paths only
- recovery kit confirmation requires a recent password confirmation and
the confirmation code printed in the current kit file (new code per
kit version), proving the kit was actually downloaded
- prune decides on the authenticated index files on the location and
refreshes the local index cache from them
- restore job marks the run failed on any error; restore runs without
progress for 6 hours are failed so they cannot block cleanup forever
- tests for safe paths and a malicious snapshot path
- removed snapshots go to a trash on the location and their data is only
freed after the deletion delay, which is chosen when the key is created
(default 7 days, 1-365) and cannot be changed afterwards; any admin can
bring them back (occ backup:trash, backup:trash:restore, web UI)
- up to three passphrase slots open the same master key (like LUKS), so
one person leaving or dying does not lock the company out; slot changes
are written to every location, announced to all admins and require a
new recovery kit confirmation, while backups keep running
- occ backup:key:slots, backup:key:slot:add|replace|remove; key init takes
--label and --delete-delay-days
- web UI: deletion delay and first slot at key creation, slot management,
trash per location with restore; all behind password confirmation
- README: key, slots (safe / CTO / head of IT), and protection against
ransomware: object lock in compliance mode (e.g. 90 days), credentials
without delete rights, provider snapshots, off-site copy
- notifications to administrators for failed backup/restore runs and
locations without a successful backup for two days (once a day)
- setup check in the admin overview: error when the key/kit is not set
up, warning for missing, old or failed backups
- security events (recovery kit downloaded, location removed,
append-only turned off, retention changed, snapshots forgotten) go to
the audit log and are announced to all administrators, from the web
and from occ; the scheduled weekly cleanup is logged only
- fix: the recovery-kit download link failed the CSRF check (412); it
now requires a recent password confirmation instead, like creating the
key, removing a location and restoring
- AdminApiController (admin only, CSRF-protected): status, create key,
download recovery kit, confirm (statement accepted + exact phrase),
backends with their usable auth mechanisms, add/test/remove locations,
start backups, schedule, snapshots, browse, queue restores
- RestoreJob runs web-initiated restores in the background; backup and
restore runs are kept apart in the run table
- admin section 'NG Backup' with a Vue 3 / @nextcloud/vue 9 page: key and
recovery-kit flow (download, tick statement, 'Yes, I confirm'), location
form built from files_external's parameter definitions, schedule, run
list with polling, snapshot browser and restore with the three modes
- auth mechanisms that depend on a user session or on files_external's
own stored credentials are not offered
API tested with curl on NC34 (status, backends, schedule validation,
confirmation refusal, browse, queued restore and backup completed by
cron); non-admins get 403, anonymous 401.
