import iphone pictures
|
|
----------------------
|
|
|
|
Use Photos app on macOS
|
|
- select library in the left sidebar
|
|
- select the pictures
|
|
- in menu bar open File > Export Unmodified Original for X Photos
|
|
|
|
The only reliable way to get some files creation time is being lost with rsync, so
|
|
we need to embed those timestamps on macos first:
|
|
|
|
```sh
|
|
PHOTOS_PATH="/Users/mwiegand/Desktop/photos"
|
|
bin/timestamp_icloud_photos_for_nextcloud -d "$PHOTOS_PATH"
|
|
rsync -avh --progress --rsync-path="sudo rsync" "$PHOTOS_PATH/" ckn@10.0.0.2:/var/lib/nextcloud/ckn/files/SofortUpload/AutoSort/
|
|
```

preview generator
|
|
-----------------
|
|
|
|
```
|
|
sudo -u www-data php /opt/nextcloud/occ preview:generate-all -w "$(nproc)" -n -vvv
|
|
```
|
|
|
|
This index speeds up preview generator dramatically:
|
|
```sh
|
|
CREATE INDEX CONCURRENTLY oc_filecache_path_hash_idx
|
|
ON oc_filecache (path_hash);
|
|
```
|
|
|
|
delete previews:
|
|
```sh
|
|
psql nextcloud -x -c "DELETE FROM oc_previews;"
|
|
rm -rf /var/lib/nextcloud/appdata_oci6dw1woodz/preview/*
|
|
```

gen previews
|
|
```sh
|
|
php /opt/nextcloud/occ preview:generate-all --workers="$(nproc)" --no-interaction -vvv
|
|
```
|
|
|
|
