Restic - Migrate
-
Man kann ein altes Repo mit Version 1 in ein Repo mit Version 2 migrieren. Ein erster Versuch von mir.
Schauen wir uns die Hilfe an.
[frank-ms7c92 ~]# restic migrate -h The "migrate" command checks which migrations can be applied for a repository and prints a list with available migration names. If one or more migration names are specified, these migrations are applied. EXIT STATUS =========== Exit status is 0 if the command was successful, and non-zero if there was any error. Usage: restic migrate [flags] [migration name] [...] Flags: -f, --force apply a migration a second time -h, --help help for migrate Global Flags: --cacert file file to load root certificates from (default: use system certificates) --cache-dir directory set the cache directory. (default: use system default cache directory) --cleanup-cache auto remove old cache directories --compression mode compression mode (only available for repository format version 2), one of (auto|off|max) (default auto) --insecure-tls skip TLS certificate verification when connecting to the repository (insecure) --json set output mode to JSON for commands that support it --key-hint key key ID of key to try decrypting first (default: $RESTIC_KEY_HINT) --limit-download int limits downloads to a maximum rate in KiB/s. (default: unlimited) --limit-upload int limits uploads to a maximum rate in KiB/s. (default: unlimited) --no-cache do not use a local cache --no-lock do not lock the repository, this allows some operations on read-only repositories -o, --option key=value set extended option (key=value, can be specified multiple times) --pack-size uint set target pack size in MiB, created pack files may be larger (default: $RESTIC_PACK_SIZE) --password-command command shell command to obtain the repository password from (default: $RESTIC_PASSWORD_COMMAND) -p, --password-file file file to read the repository password from (default: $RESTIC_PASSWORD_FILE) -q, --quiet do not output comprehensive progress report -r, --repo repository repository to backup to or restore from (default: $RESTIC_REPOSITORY) --repository-file file file to read the repository location from (default: $RESTIC_REPOSITORY_FILE) --tls-client-cert file path to a file containing PEM encoded TLS client certificate and private key -v, --verbose n be verbose (specify multiple times or a level using --verbose=n, max level/times is 3)Dort findet man alles, was man wissen muss
Als erstes macht Restic einen Test um zu klären, ob man migrieren kann.
[frank-ms7c92 ~]# restic migrate -r /mnt/Backup/Datensicherung_Home_Restic_UI/ enter password for repository: repository 50a2a753 opened (repository version 1) successfully, password is correct available migrations: upgrade_repo_v2 upgrade a repository to version 2Nun zeigt er uns die Migrationsmöglichkeit an, hier
upgrade_repo_v2Der Migrationsvorgang
[frank-ms7c92 ~]# restic migrate upgrade_repo_v2 -r /mnt/Backup/Datensicherung_Home_Restic_UI/ enter password for repository: repository 50a2a753 opened (repository version 1) successfully, password is correct checking repository integrity... using temporary cache in /tmp/restic-check-cache-3584864968 enter password for repository: repository 50a2a753 opened (repository version 1) successfully, password is correct created new cache in /tmp/restic-check-cache-3584864968 load indexes check all packs check snapshots, trees and blobs [0:05] 100.00% 13 / 13 snapshots no errors were found applying migration upgrade_repo_v2... migration upgrade_repo_v2: successDer Migrations Prozeß war erfolgreich.
migration upgrade_repo_v2: successDanach hatte ich ein Problem, weil ich das alles mal wieder als Root gemacht hatte und nun die Dateiberechtigungen falsch waren. Kurz geändert, dann kann es weiter gehen

After the migration is complete, run prune to compress the repository metadata.
Danach benutzt das Repo die Version 2. Es ist aber nocht nicht alles komprimiert.
File contents stored in the repository will not be rewritten, data from new backups will be compressed. Over time more and more of the repository will be compressed. To speed up this process and compress all not yet compressed data, you can run prune --repack-uncompressed

Uuups, jetzt ist mir der Plattenplatz ausgegangen. Ok, machen wir morgen weiter.

Kalkuliert bitte für den Vorgang den Platz der aktuell verbraucht wird obendrauf. Unter Umständen wird das schwierig.

Dafür hätte ich vorher mal eine Bestandsaufnahme machen müssen. Vergessen
Die neuen Funktionen arbeiten aber soweit korrekt, soweit ich das aktuell beurteilen kann. Werde mich mit dem Thema aber noch etwas ausführlicher beschäftigen, auch weil ich die neuen Funktionen in mein Resti UI einbauen werde.
