Muchos usuarios tienen enormes colecciones de imágenes almacenadas en discos duros adicionales en su computadora de escritorio o en un medio de almacenamiento externo (RAID NAS, discos duros externos, etc.).
It is a common requirement to develop a number of images while travelling using a laptop and then later synchronize them back to the original storage medium. However, copying images manually from the main storage to the laptop and back is cumbersome and prone to errors. The “local copies” feature of Ansel has been designed to directly support these use cases.
Create local copies of the selected images from the global menu File 🡒 Copy distant images locally. Local copies are always used when present, giving continued access to images even if the external storage is no longer connected. Later, when your primary storage medium has been reconnected, re-synchronize the XMP sidecar files back to it (and delete the local copies) with File 🡒 Resynchronize distant images.
Por razones de seguridad, si existen copias locales y el almacenamiento externo está disponible, los sidecars XMP locales se sincronizan automáticamente al inicio.
Local copies are stored within the $HOME/.cache/ansel directory and named img-<SIGNATURE>.<EXT> (where SIGNATURE is a hash signature (MD5) of the full pathname, and EXT is the original filename extension).
Local copies can be identified in the lighttable view by a white marker on the top right of the thumbnail. In addition, all local copies carry the darktable|local-copy tag to allow them to be easily selected.
