A fost lansat\u0103 versiunea 4.0 a instrumentului CRIU (Checkpoint and Restore In Userspace), destinat salv\u0103rii \u0219i restaur\u0103rii proceselor \u00een spa\u021biul utilizatorului. Instrumentul permite salvarea st\u0103rii unui sau mai multor procese, apoi reluarea activit\u0103\u021bii de la pozi\u021bia salvat\u0103, inclusiv dup\u0103 repornirea sistemului sau pe un alt server, f\u0103r\u0103 a \u00eentrerupe conexiunile de re\u021bea deja stabilite. Codul proiectului este scris \u00een limbajul C \u0219i este distribuit sub licen\u021ba GPLv2. CRIU este utilizat \u00een sisteme de gestionare a containerelor, cum ar fi OpenVZ, LXC\/LXD \u0219i Docker. Modific\u0103rile necesare pentru func\u021bionarea CRIU sunt incluse \u00een kernelul principal Linux. <\/p>\n
Dintre domeniile de aplicare ale tehnologiei CRIU se remarc\u0103 asigurarea repornirii sistemului de operare f\u0103r\u0103 a \u00eentrerupe continuitatea execu\u021biei proceselor care dureaz\u0103 mult timp, migrarea live a containerelor izolate, accelerarea pornirii proceselor lente (se poate \u00eencepe activitatea cu starea salvat\u0103 dup\u0103 ini\u021bializare), efectuarea de actualiz\u0103ri ale kernelului f\u0103r\u0103 a reporni serviciile, salvarea periodic\u0103 a st\u0103rii sarcinilor de calcul de lung\u0103 durat\u0103 pentru a relua activitatea \u00een caz de crash, balansarea sarcinii pe noduri \u00een clustere, duplicarea proceselor pe o alt\u0103 ma\u0219in\u0103 (fork \u00eentr-un sistem de la distan\u021b\u0103), crearea de snapshots ale aplica\u021biilor utilizator \u00een timpul execu\u021biei pentru analiz\u0103 pe un alt sistem sau \u00een caz c\u0103 este necesar\u0103 anularea ac\u021biunilor ulterioare \u00een program. <\/p>\n
