# reMarkable Backup (offizielle Cloud via rmapi)
|
|
#
|
|
# Ziel:
|
|
# - Inkrementeller Download in "current/".
|
|
# - Datierte Snapshots in "snapshots/YYYY-MM-DD_HHMMSS/".
|
|
# - Versionierung via Hardlinks (unveraenderte Dateien belegen kaum Zusatzplatz).
|
|
#
|
|
# Nutzung:
|
|
# ./backup-official-cloud.sh /www/remarkable/notizen /
|
|
